Secrets of Everyday Things That Will Make You Rethink Your World

want to play a game can you count how many technical gadgets you use during your day don't forget to count your router lint remover and every light bulb well 5 7 maybe 15 studies claim that the average household in the USA currently owns around 25 electronic devices in 2019 this number was more than half lower the modern speed of life makes it so easy to forget that everyday essentials have history let's do some time travel to refresh our memory chances are you'll never take your toilet paper for granted again you wake up to the annoying sound of an alarm clock this is how it looked like 1,000 years ago just kidding it's a rooster these birds did a great job helping people wake up at dawn before an American named Levi Hutchin invented the first alarm clock in 1787 but this device could only ring at 4 a.m. it took mankind 60 more years to create a technology allowing us to set the alarm time manually and around 170 more years to invent an alarm that wakes you up with your favorite Aromas and now it's time to brush your teeth which toothbrush would you rather choose the first one is actually a vintage shoe brush you should probably choose this sophisticated goldplated tool in fact it's a toothbrush made for Emperor Napoleon bonapart between 1790 and 1821 but of course people realized that their teeth needed care much earlier ancient Egyptians used branches with Frayed Ends to rub against their teeth and the first bristle toothbrushes date back to 1498 Chinese Craftsmen manufactured bristles from hog hairs 360 years later in 1857 American inv ventor hn wodsworth patented the Prototype of the modern toothbrush and the first electric toothbrushes popped up in stores in 1960 you've just washed your hair time to do some styling would you risk putting your head inside this vintage haird dryer a stationary hair dryer was invented in 1890 in France although it looks pretty claustrophobic it was very popular in beauty salons before the era of portable hair dryers came over let's move on to the toilet how about using a stone instead of toilet paper in ancient times people chose various materials to clean up including leaves grass animal Furs water seashells and even Stones rumor has it that ancient Greeks preferred using Ceramics with their enemies names and in 1857 an American named Jose gaetti first marketed the modern toilet paper he called it simply medicated paper for the water closet the paper was sold in packages of 500 sheets for 50 which is worth $17 in today's money and this is what your flush toilet would look like if you lived in 1592 Sir John Harrington godson of Elizabeth the created this masterpiece in England it's basically a water closet with a raised sistern and a small downpipe through which water runs and flushes the waste time to cook some breakfast these old kitchen stoves are no more than wood burning cook stoves but as the age of invention took place stoves evolved to fit modern homes gas stoves first appeared in 1826 And in 100 years they were used in most domestic kitchens and now let's boil some water to make tea before the 19th century most kettles were made of iron people plac them directly on the flame that's why such kettles needed constant cleaning Mesopotamian tea lovers made their kettles from bronze and it took an effort to make all these sophisticated decorations but the first electric kettle appeared only in 1891 in the USA it took about 12 minutes to boil water because the water and the heating elements were placed in separate Chambers luckily the modern kettles do it in a blink of an eye well now can you guess what this devices for nope it's not a sewing machine it's an electric toaster this is what it looked like in 1893 when it was first invented in Scotland nowadays toasters look more aesthetically pleasing and take less space speaking of space the first hard disk was the size of a cupboard and its storage was only 5 mbes but today we have 32 GB discs that are used in cameras and mobile phones just imagine how much information you could fit in a Cupboard if you could fill it fully with such discs the correct answer is a lot your friend is calling pick up the phone but get straight to the point it only has about 20 minutes of battery life this massive tool is the world's first mobile phone made by Motorola in 1973 it weighs 2.5 lb and costs $44,000 which is around 27 $1,000 in today's money time to get dressed for work would you risk ironing your crispy white shirt with such a device well people used to take that risk before inventing the first electric iron in 1882 and this cute creature is an antique gas-powered iron made at the beginning of the 20th century earlier they just put coal in the iron to heat it up is it too sunny Outdoors no problem put on this stylish accessory snow goggles were invented centuries ago to protect eyes from snow blindness and this simple item has eventually evolved into sunglasses that we use today to hide from UV light why is everything so blurry did you forget to put on your contact lenses today over 150 million people worldwide use them on a daily basis but the first guy to get This brilliant idea lived in the 16th century and his name was Leonardo Da Vinci in 1508 he described a method of directly affecting the cornea by putting the head in a bowl of water or just wearing a water-filled glass hemisphere over the eyes but it took people around 400 years to bring that idea to light and meanwhile humankind used eyeglasses the ancient ones used to have lenses made out of quartz and Metal Frames of course their design was too heavy to be considered fashionable but thankfully today we enjoy a wide variety of frames in different styles and designs with glass or plastic lenses it's time to hit the road would you mind riding this bike that's right it doesn't have any pedals first bicycles didn't have a saddle a braking mechanism or pedals that's why people simply called it the running machine also manufacturers offered models with a bigger front wheel for higher speeds thankfully speed and comfort characteristics evolved over time and continue to do so today take a look at this amazing rainbow we got to take a picture immediately unfortunately 40 years ago this photo would have looked something like this no color no Clarity it was the time when digital cameras had just appeared they weighed 9 lb and they could only take black and white images but the progress is impressive today it takes just one click to make a highresolution picture or video on your phone finally you arrive at the office and see this mysterious device can you recognize its purpose it's an old school printer the first printing devices appeared in the 15th century in Europe and they were way bigger and heavier than the modern ones that we use in offices and homes your shirt got dirty after a long day at work which machine would you rather choose to wash it the right device is a wiser choice because it's electric the left washing machine can wash up to 10 shirts but it's only operated with a hand crank someone has Spilled Popcorn on the floor let's clean this up but can you guess which of these two devices is the real vacuum cleaner the left one the right device is a vintage lawn mower the first vacuum cleaners appeared in 1901 and they were petrol driven it took a while for this device to evolve into a vacuum cleaner robot free of any tubes and wires just take a look at these two pictures these devices don't even look like they're from the same planet we all spend about 30 minutes in the bathroom every day but just because we use a lot of personal care items to make sure we look and feel our best doesn't mean these things should be stored in the bathroom to start off that includes bar soap keeping your soap near the direct stream of your shower can shorten its shelf life water will break your bar soap down and the residue will build up in your bath the best way to store your soap is to keep it on a soap dish with holes that let it dry outside of the shower razors shower Steam and the buildup of humidity can rust the blades which in turn can damage your skin even if you properly clean and dry it off after using storing it in a humid bathroom environment will shorten the lifespan of your raiser towels keeping your used damp towels in the bathroom can be a recipe for grossness warmth and humidity make bathrooms the perfect breeding ground for bacteria and towels will pick up germs that will later transfer to our skin ideally you should wash your towels after three uses and allow them to dry completely before they're used again your bath robe much like bath towels damp robes can Harbor germs and bacteria and humidity can give them an unpleasant smell if you're putting on a damp bathrobe right after showering you can consider your shower pretty much pointless instead of keeping your bathrobe on a hook in your bathroom hang it in a place where it can air dry your phone no it's not the best idea to use your phone while on the toilet and taking your phone into the bathroom isn't safe either scrolling through your feed while soaking in the tub may be dangerous and if you need your tunes while you shower don't keep your phone on the counter the steam from the shower can get inside and ruin its internal parts if you just can't go without music while scrubbing down it's worth investing in a waterproof speaker face creams when your skin cream isn't tightly closed or sealed The Damp air in the bathroom can encourage bacteria to grow those bacteria can cause skin irritation and ruin your complexion plus every time you take a hot shower the heat can cause the ingredients to separate the perfect place to store your skinc care products is a dry drawer outside of the bathroom or in the fridge that's why they call it cold cream makeup brushes it's important to clean your brushes regularly and to proper L dry them afterward to avoid bacterial growth but once you're done washing your brushes it's best to store them in a dry place standing brushs Side Up in a cup warm and humid air in the bathroom encourages mold and bacteria to spread on them and just like your toothbrush they will pick up germs that you will later smear right on your skin perfume stiring your fragrances in a bathroom can break down their molecular structure and cause them to sour to keep your favorite perfume fresh for longer look for a closet or cupboard outside the bathroom to store it in jewelry the bathroom isn't the right place to keep your jewelry even if you just take it off before stepping into the shower the humid environment will make the jewelry oxidize faster causing it to lose shine and tarnish unless it is pure gold your favorite pieces that are composed of different Metals will react faster in humidity toothbrushes when you flush the toilet with the lid up germs can spread up to 15 ft and bacteria will most likely get sprayed all over your toothbrush dentists recommend keeping your toothbrush as far away as possible from the toilet in a place where it can dry completely the best place is covered like in your bathroom closet or a medicine cabinet and forget about those little plastic covers for your toothbrush yep they encourage bacterial growth in the that little cramped space in a human environment oky doie are you grossed out yet yeah me too so now you know what to do fitness trackers and fancy smart watches are fine for monitoring your heart rate and even the miles you cover on a run they're not so good at measuring the number of calories you burned though a 2017 study from the Stanford University School of Medicine showed that fitness trackers and SmartWatches have error margins of less than 5% when it comes to measuring heart rates that's pretty good so you can be confident in whatever reading you're getting the problem is with the devices measuring energy expenditure accurately or calendars burn even the best was off by an average of 27% the worst was off by a crazy 93% that means they're very unreliable and shouldn't be trusted fitness trackers don't work well for measuring calories because we all have different heights weights diets and many other things that means we all burn calories at completely different rates The Trackers are often programmed with a preset average height and weight so if you're going to use one take it with a grain of salt unless you're trying to reduce your sodium intake sunscreens have only one job to do and that's protecting us from the harmful ultraviolet rays in 2017 though a study found that many popular brands fail to protect at all with only one in four working most sunscreens didn't protect users from ultraviolet A and B Rays at all some manufacturers also claim that these products had an SPF of over 50 which sounds very high quality but the actual SPF was much lower than that the misleading labeling means we aren't as protected as we think when we're at the beach so when you're out shopping for sunscreen make sure you look at the ingredients and apply more than you think you should ooh sports drinks an essential item for anyone working out these bright colored drinks are filled with Electro lights that will increase your performance and rehydrate you fast the problem is we're not all athletes so most people would be better if they just drink water instead sports drinks are made up of water with some minerals and lots of sugar coloring and flavor those minerals are electrolytes which can help our bodies go longer your exercise habits the duration and the intensity of your training all come into whether you really need that extra boost while sports drinks can benefit athletes engaged in long or intense training they're not really necessary for most gym goers sports drinks are probably pointless if you're only doing like to moderate exercise like walking or jogging over a short period of time after using a toaster for most of your life most people still haven't figured out how to get a perfect heat setting it turns out that burnt toast is probably just down to a simple misconception those numbers on your toaster aren't heat levels at all they're actually minutes the dial is basically just a timer that means all you need to do is look up how long it takes to toast certain things and you'll never ruin your breakfast again hey I like burn toast I'm used to it most of us rely on wireless technology to carry out normal everyday tasks it can be very frustrating when technology stops working and interrupts your day in fact the only thing more frustrating might be not knowing why it isn't working the worst culprit here is your cell phone it'll often show really great reception but somehow can't make a phone call the bars on a cell phone actually don't mean anything the way they receive the signal differs a lot between different makes and models of a phone there's even a big difference between what the bars mean from one phone to another meanwhile watching a progress bar showing the percentage of time left to complete a download on our phones or PC can be tedious sometimes they just seem to be stuck doing nothing bad news they don't really work at least not in the way we think the system updates the progress bar when certain Milestones are reached a progress bar at 50% doesn't mean half the file has been downloaded almost all the f files could have been downloaded the point of them is to give you something visual to look at progress bars aren't accurate because downloads and transfers have too many variables beyond the system's control internet speeds and network availability are the coordinators of how quickly a download will complete while your computer's hard drive determines how fast things process and information gets put in the right files it's probably best to make a coffee or set things up to download while you're in bed instead of constantly checking up on an incorrect progress bar elsewhere stopping at a crosswalk and pressing the button hoping the walk signal will come up might just be a waste of your time it turns out that all that button pushing could be for nothing some crosswalk buttons need to be pressed but others don't do anything at all the crossing symbol will just light up whenever it wants to some crosswalks even switch between kneading and not needing a button press depending on the time of day that said it can be difficult for all of us pedestrians to determine whether a crosswalk button works or not when in doubt just push the button anyway you don't want to stand around waiting for no reason with more people going into the water and sharks well living in the water the fear of bumping into a not so friendly shark is ever increasing this shared water space has pushed many companies to try to create shark repellents this sounds like a good idea that should help keep both people and sharks more safe companies have tried everything sprays wet suits magnets wax and even electronic devices to repel the scary fish the bad news is none of these products are confirmed to actually work one in particular makes the sound of an orca sharks aren't too fond of being in the same area as them but does pretending you're an orca stop a shark from biting you if you feel safer using them then go right ahead but if you're looking for a shark deterrent that's 100% effective it's just not available here's it actually works stay out of the water rushing into an elevator and repeatedly pushing the closed door button in the US is basically a huge waste of time unless you've got the special trick in 1990 the US passed a Disabilities Act for elevators which meant that elevators had to ensure that someone with a disability had time to get inside one if you're on crutches use a cane or travel in a wheelchair you don't have to worry about someone accidentally closing the elevator doors before you've had a chance to pass through them there's one important loophole to this if you're an emergency or maintenance worker you'll have access to Keys and codes that make that button operational this is just another example of a placebo button you're invited to push just to make you feel like you've done something that impatient finger poking isn't doing anything getting a bit warm or cold in the office better adjust that thermostat unfortunately in the vast majority of Office Buildings the system controls are kept inside air ducts not on the wall technicians installed dummy thermostats to give workers the illusion that they're dramatically changing the air conditioning or heat some are set to change 1 or 2° but they're often not connected to anything at all dummy thermostats came about around the 1960s as heating Prices rose building leases often required employers to stay within specific temperatures face with this problem fake thermostats became a new rage for businesses they offer people some feeling of control while keeping the temperature in the right range now ever come across some premium PC cleaning software that promises to clean your PC and make it go as fast as when you purchased it yeah these thirdparty PC cleaners are often made to seem like they really work but they usually don't do much of anything at all they'll detect non problems and list them as problems the worst example of this is when they list browser cookies and temporary files as having an effect on the computer's speed when they don't it's it's better to stick to the operating systems built-in cleaner it'll work fine if you ever need to clean your computer and save you having to Splash out on one that does pretty much the same thing well that's all I got time to burn some toast after a bad day at work you decide to hide yourself from the rest of the world you turn off your phone and your laptop and lock yourself inside the bathroom you jump out of your meditation when you hear a beeping sound it's your toothbrush saying data transfer completed your robot vacuum knocks at the door looks like it must be after you robot vacuums make a map of your home to get around and plan cleaning better they can share this map with other gadgets via Wi-Fi and store them in the cloud when advertisers get access to those Maps they can get an idea of your home size your income level and lifestyle to send the right ads your way H vacuums don't have microphones but their navigation systems can be repurposed to listen to your conversation they map the room with a laser beam directed at objects soundwaves affect that light if you collect that data you can convert it back into soundwaves and identify what someone said headphones and microphones are based on the same idea headphones turn electrical signals into sound and microphones turn sound into electrical signals if you plug your headphones into the microphone Jack they'll work as a microphone bad guys learn to do it remotely without your consent there's malware that retask your computer output channel into input Channel it can record sounds from across the room even when the headphones are in their Jack and the microphone is turned off and disconnected from the computer then it compresses the audio and sends it over the Internet there are computer mics that look like regular ones but have microphones and a built-in SIM card in them the mics are so powerful they can even record whisper and broadcast that audio in real time to activate it you have to call the SIM card number and it goes on silently to deactivate it you can send an SMS to the same number some employers confirmed ease dropping on their staff using that technology a smart toothbrush remembers every move you made with it and shares it with you when you're done brushing it also connects to your iPhone or Android using an app and sends data on your brushing habits to your dentist they can watch over your brushing process and give you tips tips on how to take better care of your teeth smart watches fitness trackers and other smart wearables monitor your health and can determine if you're walking running or driving with their built-in sensors if third parties get control over that data they can also monitor your hand movements as you unlock your phone and your PIN code at the ATM or your password at the computer the gadgets are smart enough to accurately guess all that secret data most of the time they can also find out the email address you use when you registered with the app to identify who you are pacemakers and other health devices send patient data over the internet in theory criminals could obtain it during transfer and change it to look like the patient needs hospital treatment that would make them leave their home and bad guys could take advantage of the situation smart toys that have cameras and microphones in them can record videos and sounds and send them to the toy maker to keep prices on Smart toys lower they don't add expensive security mechanisms to protect that data if cyber criminals get a hold of it they can steal pictures videos or audio and even identify GPS coordinates of the house LED lights equipped with sensors and connected to video cameras can watch over and listen to conversations over a large distance this technology was used at one large airport for security and comfort reasons cyber criminals went further and learned to use ordinary light bulbs for ease dropping on conversations to do it they need a clean line of sight between a powerful telescope and the bulb of the right thickness it won't work if you have drapes on your window when you're talking or listening to music there are changes in air pressure on the surface of the bulb and it's shaking a bit a special converter can turn data on the sounds from electrical to Digital internet connected thermostats can be operated remotely and that made them desirable for cyber Crim criminals they once got access to millions of debit and credit cards data through a large retailer heating and cooling system other bad guys found a way to remotely lock smart thermostats controls and demanded Ransom to unlock them smart fridges can tell you when it's time to buy milk as they track your food preferences and have great connectivity smart dishwashers coffee machines washers and dryers are also collecting and transmitting your data even at moments you don't think they're doing it criminals can make use of that data to find out a lot about your schedule and guess when you aren't at home your voice assistant makes your life easier but it must listen to you 24/7 to make that possible they never record anything you say before you activate them with your voice everything that follows is stored in the cloud and can be of use for different companies they can learn what music you like to listen to what news stories interest you the most and where you make your reservations some some companies hire human reviewers to listen to commands to see if voice recognition works well and improve its accuracy Xbox admitted they also hired people to listen to users audio to improve voice command features the problem is that it made some recordings by mistake and strangers were listening to personal chats home security cameras can take videos pictures and audio recording and upload them to the cloud without you even knowing manufacturers say it's done to improve object recognition you can get access to that camera footage remotely using an app there are programs that can guess a CCTV password and forward the video stream to a third-party computer they can also get control over the camera and disable any signs of monitoring like red light so it seems inactive almost every car has an event data recorder that tracks information on its location average speed road condition and even your preferred route out your computer on Wheels constantly streams that data to its manufacturer they use it to try to prevent accidents and make other improvements it's not clear who owns all that car related information so in theory it could end up at a third party Smart TVs run an operating system just like computers and also have a file system cameras for video face recognition and a microphone they are always connected to the internet and if cyber criminals get access to a T TV that can change certain settings and record audio even when the TV is off they could also watch you through the camera and use the smart Gadget to move to other devices on the same network like your laptop well I'm totally creeped out so what can we do about it you can disable automatic content recognition to stop your TV from giving you viewing recommendations and limit voice activation function for a safer experience you'll find that option in general or advanced settings under viewing information or viewing data you can also disconnect it from the cloud all together always change default passwords and usernames on new devices to secure your network make up a new password for every Gadget every now and then you can also split your modem and use one Wi-Fi signal for laptops iPads and the like and the other for security cameras don't forget to turn off the Wi-Fi router when you leave the house to minimize the risk of a digital intrusion whenever possible enable two-step authentication that demands physical access to the device to log in always install software updates as soon as the gadget manufacturer offers you to do it updates have patches for detected vulnerability issues cover your laptop camera with a dark colored tape when you aren't using it delete your conversations with a voice assistant you can do it at the manufacturer's website or app another option is to activate the delete by voice function in settings then you'll be able to tell the assistant to delete what you just said or your last conversations you can also mute the device when you aren't using it and choose not to send data to manufacturer to help them improve Services if you have a thermostat that connects to your voice assistant tap the microphone icon on its screen and set voice control to off you won't be able to activate it remotely and it won't be able to listen to wake words and send your audio anywhere okay have a nice day okay so right after being processed plastic water bottles aren't the size you buy at the store even a gallon water bottle starts its life as a small tube later it gets heated inflated and shaped into the bottle you know boy I can relate to the heated and inflated part now not all potato chips are actually fried potato slices some companies use a mix of potato flakes corn starch and and water to produce chips this mix is then pressed into a dough and chips are cut out from it with the help of shaped molds then the chips are fried which takes about 11 seconds after that all excess oil gets drained and the chips are seasoned and packed there's a legend that only two people in the world know the original recipe that gives Coca-Cola its signature taste these people aren't allowed to travel together so that the recipe never gets lost even though it's just just a popular Legend not many people are aware of all the ingredients of the world famous drink one of them used to be the cola nut hey I used to be a cola nut you can find these nuts inside the fruit of the cola tree each fruit is about the size of a Chestnut and has between two and five Cola nuts inside the cola fruit and nuts are packed with caffeine nowadays Coca-Cola is said to no longer contain the cola nut extract it's rumored to have been replaced with artificial flavoring but since the drinks recipe is such a closely guarded secret no one knows for sure hey maybe we can ask Pepsi these days it's quite simple to make a mirror producers take a regular sheet of glass as a base then they apply a reflective coating this usually means spraying a thin layer of either silver or aluminum onto the back of the sheet of glass this process is called silvering some kinds of car wax contain caruba wax also called Brazil wax that's a vegetable wax people get from the fronds of the caruba tree growing in Brazil to get the wax the leaves of this tree first get dried and then beaten o oo ow ow this is how you can remove the powdery wax now pencils first their leads are made by mixing clay and graphite powder this mixture is then baked after that pencil bodies are made if if they're wooden the material should be chosen carefully it should be soft enough to sharpen but tough enough not to break when the pre-cut sections are delivered to the factory they have grooves cut in them these grooves will later accommodate the leads then special glue is added this way the leads will stay in place next every second section is sent to a special conveyor and the leads are placed in the grooves then another section is glued to the one filled with leads we get a large multi pencil sandwich M sandwich I'm getting hungry the two parts of this sandwich get compressed and cut lengthwise then they're shaped and form separate pencils lava lamps were invented in the middle of the 20th century the magic happening inside is due to the right amount and type of ingredients two of them are oil and paraffin wax the oil helps the wax heat up and once it's heated it starts rising up slowly once the blob reaches the the surface it cools down and sinks back to the Bottom now nutmeg is a strongly flavored spice used in many Cuisines all over the globe despite its name nutmeg isn't a nut it's technically a seed native to the Spice Islands and East Indies Tropical Islands nutmeg grows on trees and the seed itself is sealed in a shell once it's ripe the outer shell cracks open chocolate comes from the cacao tree which is native to the Amazon these trees also grow in Central and South America and some other tropical climates in Africa and Asia the seeds of the cacao tree are very bitter they have to be fermented to develop the flavor you're used to after this process the beans get dried cleaned and roasted the shell is removed and crumbled bits of dried cocoa beans are ground a cocoa Mass this mass is then used in the production of all kinds of chocolatey things m [Music] in the past people used to chew different types of aromatic substances including beeswax tree resin or even aromatic Twigs but modern-day chewing gum is made of a natural latex like ingredient called chickle it gets extracted from trees modern marbles are made from glass the first step is to melt recycled glass and previously rejected marbles that turned out to be too small or too big about 15 hours later the mult glass is ready for processing a special cutter bar moves through the stream of liquid glass every half a second it separates small pieces of glass there are future marbles called slugs the faster the cutter bar moves the smaller the marbles are after that the still hot slugs are sent through several constantly rotating metal rollers they keep the Slugs apart and also cool them these riged rollers also give the marbles their spherical shape as for the Marble's final coloring it's determined already at The Melting stage that's when the air passes the coloring through the glass you can find Springs everywhere from tools electronics and toys to pens and mattresses they come in different forms for example torsion wire extension or compression springs when a spring is made a steel cord is passed to a dealer how thick this cord is depends on what kind of spring we need the derer unwinds the roll and sends the cord to a computer controlled forming machine that's where the cord gets coiled to the needed length and cut into pieces now to produce tomato ketchup one of my favorites you need tomato paste or puree sugar or some other natural sweetener salt spices vinegar and onion powder first the needed volume of the tomato paste is heated while being constantly stirred then other ing ingredients are added as well before the ketchup is bottled it has to go through several cooling stages meanwhile bottles are already aligned and waiting to be filled with the ketchup this usually happens automatically at the end of this process caps and labels are added to the bottles cashew nuts are rich in plant protein healthy fats and fiber and low in sugar but there's some of the most expensive nuts out there and no wonder the cashew tree native to Tropical regions of Brazil produces a long stock called a cashew apple it resembles a small pair well then why don't they just call it a cashew pear anyway at the end of this stock there's a kidney-shaped nut it's protected by a double shell that contains a poisonous oily substance it's the main reason cashews aren't sold in their shells like peanuts or pistachios cashews need to be dried and roasted first this removes the toxins and makes the shell brittle and much easier to remove nail polish as we know it today is a rather modern invention it became popular at the beginning of the 20th century different companies use different kinds of chemicals and ingredients to produce nail polish but one of these ingredients is always the same nitrocellulose this substance is actually liquid but it gets mixed with plasticizers they make nail polish more flexible and allow you to wear it longer the process of creating ice cream sandwiches is pretty simple first ice cream gets whipped it's done to add some air the resulting substance is then sent to the next part of the assembly their two lines of Wafers are already sandwiched together and ice cream is simultaneously injected between them it happens so quickly that more than 100 ice cream sandwiches can be made in a minute M how many can I eat in a minute there are all kinds of plastic brooms out there but there's one type that's made from recycled plastic bottles with people buying 1 million plastic bottles all over the world it's a cool way to reuse plastic tires production is a multi-step process tires are made from more than 15 Main Ingredients among them there's synthetic and natural rubber carbon black pigment and chemical additives giant mixers stir these ingredients under high pressure and temperature the final result is almost always thin rubber gum it gets rolled into sheets after that tires get assembled on a special machine different kinds of cloth rubber and metal are used for the production of a tire finally the tire gets cured in a special press under more than 300° of heat and high pressure this process lasts for 12 to 15 minutes when they make darts the flight shafts are produced first 10t long aluminum rods are put into a special machine it has a few cutting tools that work from several angles at the same time the rod turns into shafts there are threads cut into each flight shaft so that it can be later attached to the dart Barrel that's the part you hold and fling on the other end a cross saww makes slots for the arrow flights at the same time brass rods turn into the barrels on another machine grooves are cut into the barrel surface this makes them easier to hold and finally they produce a dart point it's done with the help of a hydraulic press it forces pointed steel into the hollow part of the barrel and darts all there is about how they make darts well it's a nice Sunday afternoon and you're shopping at your regular grocery store when you stumble upon a bloated package in the fresh produce aisle you check the product information it seems well within its expiration date then why the unusual shape you may wonder the answer is not always straightforward for some types of fresh products such as meat fish or seafood sometimes even salads and cheese scientists came up with something called map or modified atmosphere packaging to ensure that these types of products with a relatively short shelf life stay fresh for as long as possible a combination of gases is introduced in the packaging it happens even before the product reaches your local grocery store a French professor at the monilia school of Pharmacy stumbled upon this method after we noticed that fruits tend to stay fresh for longer periods of time in low oxygen storage conditions the types of gases in mapped packaging can vary from product to product but the main idea is to replace or reduce the content of oxygen it's generally replaced with either nitrogen or carbon dioxide keep in mind that just because a bloated bag of salad is within its expiration date it doesn't mean it's always safe to eat the gases inside the bag may very well be there for their own purpose but they can also be a sign that the product is spoiled that's why the best course of action When shopping would be to check if the product is not expired if it's still within the date check for any unusual odors or damage to the packaging if something seems off it's best not to risk it you can reach out to any of the store staff if you have any questions or concerns most supermarkets these days have a layout which allows for a logical shopping order like buying non- perishable items first then adding refrigerated or frozen products fruits and vegetables should come last since you won't want them at the bottom of your shopping cart nobody likes a squished tomato while I'm on the subject of fruits and veggies try to get them earlier in the morning if possible veggies that have been sitting out all day may lose some of their shape and texture while others may be a bit wilted away quick tip on Waste Management never buy more produce than you intend to use in a week most fruits and vegetables don't even last that long so it's best not to give into Cravings shopping on a full stomach might help with that as well just as much as going shopping with a pre-made list of things you need to buy thoroughly inspecting the package of every product might save you some hustle later as well refrigerated products need to feel cold to the touch whilst Frozen ones need to be solid and with no sign of leakage when you get home make sure you refrigerate all the necessary items as soon as possible generally they shouldn't be out of the refrigerator for more than 2 hours otherwise their quality won't stay the same buying potted herbs from the grocery store may not be the first thing on your list but it's surely something to consider not only are they available for a fraction of the cost but they're also easy to grow and take care of just picture a nice herb garden right there on your balcony or even in the kitchen wouldn't that be nice you'll always have fresh basil to top a mouthwatering pasta dish since you're still at the grocery store pick up some coffee filters while you're at it you may not have a machine at home that actually uses filters but there are a lot more things you can use them for around the house they can be used for straining liquids safely stacking Delicate China in your cupboards or even polishing windows or shoes for that matter if your favorite fruits and vegetables are on sale but buying large quantities would mean they go to waste consider freezing them you can stock up on items for smoothies especially for the colder season when there are limited options for fresh fruits and don't just grab the first thing on the Shelf especially if it's likely to go bad quickly stores restock their produce following a first in first out layout so the items at the back of the Shelf will always be a tad bit fresher the same goes for tea if you prefer it to Coffee switch to to buying loose leaf tea and you'll not only reduce the cost you'll also be able to make your own homemade tea Blends loose leaf tea also has a stronger flavor than tea sold in tea bags as for the other household stuff stock up on items such as light bulbs paper towels or batteries chances are you'll always be needing at least one of these items so it's best to buy them in larger quantities when on sale they never go to waste and let's face it it's always annoying when you run out of battery at home and your TV remote stops working hey tell me about it try to reduce the number of times you go to the grocery store to buy just one item it's inefficient and most likely you'll end up buying things that you don't actually need uh that shopping list starts to make a lot more sense now doesn't it another list worth making the one containing whatever you have in the fridge try to create such a list at least twice a week meal planning for at least a week in advance will also help you with reduce impulse buying if you already know what you'll want for dinner on Wednesday why add anything else to the card if it's unnecessary at the same time start getting creative with your leftovers there's no need for them to go to waste when you can mix and match or add some additional herbs and flavors to spice them up store leftovers in transparent containers for added visibility and don't be afraid to set out a leftover day during the week it's also nice to look at them as ingredient ingredients rather than leftovers use extra leftover pasta or steamed vegetables for a frittata or an omelet blend together cooked vegetables with some tomatoes to create a pasta sauce put together some wraps for the next day's lunch with anything from leftover cooked rice to meat and vegetables or if you're really looking for the easiest method to save leftovers you can always turn them into soup last night's vegetable side dish can turn into a wholesome lunch if you simply L add a can of broth and blend it all together even a 2-day old loaf of bread can be salvaged if you cut it diagonally sprinkle the slices with some herbs and olive oil and pop them in the oven for a couple of minutes you'll then have yourself some nice homemade croutons for that previously mentioned soup a little label knowhow never hurt anyone either be on the lookout for ingredients you've never heard of or those you can't pronounce an item that usually has more than five ingredients listed on the packaging should be avoided even the way you carry your groceries in the supermarket can affect how and what you buy if you prefer baskets to shopping carts you're more prone to impulse searches that's with a study published by the Journal of marketing research claims it happens due to the effort you put in actually

there's anyone else waiting in line behind you good luck sliding out the food Arrangement on the shelves can also pose a threat to both your budget and your habits since people are more inclined to

will try to cram into it next time you pack your stuff try to stick to a 54321 rule this rule says that for a one we vacation we can easily limit to five pairs of socks and underwear Four Tops three bottoms two pairs of shoes selected by how active you're planning to be on your vacation and one hat but I suggest we add one more item to this rule a lightwear rain jacket like this one it takes no more space than two pairs of socks but it can be a lifesaver for unpredictable weather conditions if you're afraid your clothes will get dirty fast and you'll have to hide those ketchup stains on your vacay photos there's a solution on how not to do it have you heard of on the-go detergent these are small packets you can throw in your suitcase and hand wash your clothes in the sink binder clips may

grab one and cut it in two halves next you're going to need an elastic band then roll the sweatshirt you need in a very tight roll and put it in between the two bottle Habs secure this weird

with your portable charger if you're a frequent traveler here's a piece of advice for you never ever unpack your toiletries this way you won't forget anything next time you fly the best solution is to keep a separate kit with all the products you need like a contact lens case or a toothbrush but if you still don't have one it's high time you made up your goodie bag with your Essentials you probably already have small bottles at home make sure it has an inscription on them claiming the bottles are not over 3.4 Oz if you plan to take them on board however if you have no bottles there are plenty of them online like this one the kit you want to buy should have funnels to pour any shampoo or gel easily some of the kids even have Scoops which is great you can do ice cream no sorry they help portion out a small amount of moisturizer so you won't spoil the entire jar with your finger grease however there are a couple of things you better keep in your pockets and not in the toiletry kit like hand sanitizer and lip balm while everything's pretty clear with hand sanitizer lip balm has way more uses than you can imagine if you have dry cuticles lip balm will make them soft and pliable again if you want to clean up your makeup lip balm and a Q-tip will work wonders unless it's minty you can even use it instead of eyebrow gel if you left yours at home and it can also help tame flya away hairs

you're traveling to the UK you can stick to this adapter a small spray bottle can significantly upgrade your look yes it can for example if your favorite t-shirt tends to wrinkle a lot you can sort of iron it with a spray bottle hang it up and spray it with water the wrinkles will disappear and your T-shirt will look fresh and presentable hopefully now let's talk duct tape duct tape in your luggage may be pretty stress relieving now picture it you're going back home with a whole bunch of gifts you bought for your family and friends whoops the zipper on your suitcase just didn't resist the pressure and it busted duct tape is coming to the rescue yeah a suitcase wrapped in duct tape might look somewhat funny but it's still better than shelling out a pretty penny on a brand new suitcase you weren't planning to buy yeah that does make laundry bags may come in handy when you separate your dirty clothes from your clean ones I know you can do that with plastic bags but laundry bags are sort of more eco-friendly plus once you come home they'll spare you some time you won't need to dig through your suitcase trying to find all the clothes you want to wash you'll just need to throw the laundry bag into the washing machine if you're traveling to the seaside you might want to consider grabbing a quick dry towel like this one they're usually made of microfiber that dries much quicker than regular cotton plus these guys are pretty low maintenance as they can be machine washed at up to 130° F next on dryer sheets you know we all sweat and our feet sweat too especially if we walk Miles and Miles exploring a new location so when you return to the hotel and take your sneakers off woo just put a Dyer sheet in each sneaker it'll absorb the odor and your sneakers will be ready for

want to say to play it safe create a set of flashcards with essential vocabulary to help you out in basic situations a favor snack may be one of the most commonly forgotten by traveler items yeah they do give you food on the plane but sometimes you may want to have an alternative plus your snack can even save your budget in case you have a long connection the prices in the airport lounge are crazy even if you travel in summer it doesn't mean you don't need any warm clothes make sure you have a zip hoodie or something of that kind especially on board thing is you never know if it's going to be cold or hot on the plane sometimes it gets pretty stuffy in there there but it can also be freezing cold airplane blankets as well as tray tables are swarming with germs so it's better to have your own clothes to keep warm as for tray tables I doubt you can bring your own on board so just don't forget to clean them with an antibacterial wet wire and have a safe fly you're trying on a pair of jeans a dress or a jacket and are about to dig your hand into the pocket when you realize there's no depth to it the pocket is simply not there but why would anyone create Pockets you can't put anything in and uh now would be a good time to pick your iPhone up from off the floor well the reason for fake pockets is simple if a clothing item has a specific cut or shape Pockets May spoil it they can alter the item shape either in the warehouse or already on the retail rat the solution getting rid of pockets in key areas Plus fake pockets are obvious obviously cheaper and they don't get stretched out interestingly this practice goes back to the 17th century that's when Pockets were actually removable they resembled small bags and women for example could move them from one outfit to another unfortunately it was also very convenient for pickpockets they could grab such a pocket and run off with it then clothes became more streamlined and slim Pockets started to be sewn right into them instead of attachable bags this was believed to make the shape of a person's silhouette more alluring but soon Slimmer skirts came into fashion and Pockets went out of it and people started using handbags instead these days most pockets are real but some of them are still fake so how can we make sure that we don't actually turn a fake pocket into a hole thinking it's a real one well first of all take a look at the stitching along the edge of the pocket where it's supposed to open up if you see a single loose thread just snip a piece of it and start pulling gently if the pocket is real the thread will easily come out but if you feel that the stitching won't budge most likely you have a faux pocket on your hands if this is the case just leave it be now let's move on to some other everyday objects that may be hiding some secrets for example those lines on some kinds of chips for one thing they help with the distribution of spices and Seasonings in other words all those substances that make your chips taste like cheese are mostly stored inside the lines plus the lines make chips crunchier highlighters are filled with a special semi-transparent fluorescent ink that can glow in dim light yellow and light green Hues are the most popular because they don't prevent you from seeing the text after black and white photocopying photocopiers perceive yellow and light green marks as almost non-existent and don't print them now back in the day the first genes had one problem workers and miners who were the original jees wearers put too much pressure on the poor piece of clothing as a result the seams couldn't withstand the stress and tore so tiny metal studs were invented to prevent this from happening most metallic zippers have a hidden lock inside them that's why you shouldn't leave the zipper handle in an upward position when you pull it downwards it automatically lines it's all thanks to several tiny grooves hidden underneath the handle now about those horizontal lines on plastic bottles they help hold bottles up some bottles are produced from soft plastic without the lines they wouldn't keep their shape instead they would twist easily or even break bath foam isn't only for fun or a nice smell it helps regulate the temperature too the bubbles keep the water hot and you can enjoy your bath a bit longer with or without your robber ducky ever notice that layer of clear liquid and gel pens it's called the ink follower or stopper fluid the gel in such pens contains pigment particles dissolved in a polymer solution the gel should be thick enough to keep the pigment particles suspended but also thin enough to flow first onto the ball and then the paper the main task of the stopper fluid is to be a barrier to prevent the gel from evaporating or leaking out without this transparent fluid your gel pen wouldn't function the fluid always stays in one position and doesn't get dissolved with the gel neither does it move backward or flow out of the pen the holes in the bottoms of your earphones allow air to circulate up and through the speakers it allows to increase low frequencies making the base sound duper the quality of the sound also becomes much better some plastic milk containers have dents on their sides try as they might they just cannot park without some damage nah I made that up these dents serve several purposes for one thing when milk spoils this process usually causes swelling and high pressure buildup inside the container oh boy that's when the dent comes in handy it pops out and doesn't let the jug blow up plus if you ever decide to freeze the milk it will expand like any other liquid and then again the indentation will pop out and prevent the container from breaking inside your freezer that's a good thing airplane Windows have rounded edges and that's a crucial safety measure it prevents aircraft accidents weak spots are usually situated in the corners if airplane windows were square or rectangular each of them would have four potential weak spots under pressure they would collapse if you look closely at a tram's overhead lines you'll see that its contact wires zigzag back and forth instead of going in straight line the thing is that all trams have pantographs attached to the roofs the upper part of the Pantagraph is gradually worn down by the overhead wire and eventually needs to be replaced to wear it down evenly the wire is not installed strictly along the tram's path but in zigzag patterns as the tram moves The Pantagraph slides along the wire and it wears down evenly you might have wondered why some gas cans have two holes with caps one bigger and one smaller before I thought that the little hole was used when you poured something into a smaller container but I was wrong a very infrequent occasion in reality you're supposed to uncap it before you pour the gas inside the bigger hole to prevent it from glugging and spilling on your clothes and on the ground most of the button holes on a shirt are vertical but the top and sometimes bottom ones are horizontal the reason is simple these two buttons slip out more more often than others luckily producers have found the solution that can prevent these buttons from slipping out horizontal button holes what engineering buttons tend to slip out less from such button holes stick sachets of sugar or salt are easier to open than many people think there's no need to tear off one of the ends the right way is actually to tear them down the middle some boots have loops sticking out on the back their main purpose is to help you pull your shoes on easy you just tug on the loop while you're pushing your heel into the boot you can also use these Loops to hang your boots on a hook when they're dirty or when you want to dry them after washing or you can run your laces through the loop if you want to tie them around your ankle when you're on board the plane you might spot a little triangle over your seat such triangles show the flight crew the best spots to check the plane's flaps through the window just in case they're flapping if your shoes are really slippery just take take a bit of sandpaper and rub it on the soes for better traction they'll become more grippy and you'll be able to wear them out in the rain now if they get too wet they might turn gripy but that's only if you have talking shoes if you drill several holes at the bottom of your garbage can putting in and taking out trash bags will become much easier you won't have any problems with suction you can usually find some silica gel in bags shoes and many other things you buy this shell absorbs excess moisture don't throw it away each time your shoes get wet put a few packets of silica gel inside the thermos wasn't actually invented to keep your coffee warm it was made by a Scottish scientist who just wanted a safe place to put his chemicals at a stable temperature so he took two bottles put the smaller one inside the bigger one and vacuumed out the air between them well anyway thanks for the hot coffee imagine you're an artart detective and your task is to explore the Mysteries behind the world's most famous paintings I'm talking about works from Da Vinci Michelangelo Picasso so grab your magnifying glass as this journey is about to begin first off on your list is Rome after enjoying delicious pasta you head to the cine chapel home to the world's most famous ceiling oh and you know how they say Michelangelo painted the fresh goes lying down this is just a myth actually the painter created a complex system of platforms that allowed him to paint standing you're checking out the creation of Adam that Fresco in the middle the Italian artist Michelangelo the author of this masterpiece was widely known for his study of human anatomy art experts argue that the right part of the painting is an anatomically correct depiction of an enlarged brain to proof check this you try overlapping a a picture of the organ and the artwork it seems to be a match the cerebellum the optic nerve and the pituitary gland are all there even the floating green scarf thingy appears to match the vertebral artery some researchers think it was Michelangelo's way of depicting knowledge and wisdom but you have to sleep on it to decide what you think moving on you catch a train and arrive in Florence time for a quick gelato break then straight to the Academia Gallery one of Art's most celebrated sculptures is waiting for you inside Michelangelo's David David is a 17t tall marble wonder it was carved for about 3 years the mystery surrounding it is to figure out the statue's true expression looking at him from below you'll think his face is Serene and peaceful but art historians argue that this work was largely misunderstood apparently his body hides a very different story story take a closer look and you'll notice his brows are frowning and the veins in his arms are popping out that doesn't look too relaxed does it Michelangelo's idea was to depict David right before an important confrontation so maybe he wasn't all that Serene after all Italy is so rich in art you can't leave just yet you're still in Florence you pay a visit to the famous uii Gallery many famous paintings are hosted by this Museum but you're checking out belli's Prima Vera or spring this artwork is mysterious from the get-go experts can't say the exact year it was commissioned it remained Untitled for years until the painter Giorgio vasari finally came up with a name for it usually when critics and viewers admire this painting they focus on the figures in the foreground but in this case the actual work lies in that belli painted over 46 different plant species with almost identical precision and oh in the painting overall these plant figures are repeated over 200 times unbelievable I'd say the last visits were full of Impressions weren't they ready to keep going a plane ride later you arrive in Paris the City of Lights Beret and the famous Mona Lisa you go through the museum de and come to Leonardo da Vinci's masterpiece laio there are many theories regarding this work of art and you dive into some of them a strong case has been made that the Mona Lisa could be a self-portrait of Da Vinci himself historians have thoroughly compared Da Vinci's face and that of the Mona Lisa and guess what they appear to be strikingly similar oh and then there's the smirk Theory dentist and Art Expert Joseph Bartowski claims to have discovered the secret behind Mona Lisa smirk he says her tight facial expression is a typical indication of someone who lost their front teeth could it be so also in 2010 the Italian committee for cultural heritage found a collection of symbols hidden in the painting these are only visible through highly technological magnifying lenses but they showed that Leonardo inscribed an LV inside Mona Lisa's right eye experts guess that this is Da Vinci's signature but the other symbols a c in the left eye and a 72 in the arch of the background Bridge are still very mysterious phew you covered a lot of ground on this one ah of course at the end of your visit remember to test if her eyes really follow you around now you're headed to Amsterdam to check out the reiches museum you came to see a specific rembrand painting that hides a mysterious story the night watch is one of Rembrandt's most famous paintings but experts argue that the name of the painting and its content are mismatched let's take a closer look the painting depicts a large group ready to embark on a mission REM Brand's technique is called Chia roscuro highlighting the contrast between light and shade until 1947 art critics believed the painter was depicting a nighttime scene but when the painting was cleared of a thick dust layer it became clear that the scene was happening in broad daylight with the sun streaming down from the top left now it's too late to change its name to the day watch while in Amsterdam you find a museum dedicated to Van goart did you know that he painted over 900 paintings during an impressive period of only 10 years anyway the van go Museum hosts the biggest collection of yellow sunflower paintings you'll probably see in your life actually almost all of vano paintings feature dominant yellow Shades this particularity of his art may be a result of how he saw the world some art experts have speculated that one of Van Go's remedies changed his color perception making him see more yellow around him okay so this trip just keeps getting better the next stop on your list is the United Kingdom then on to the National Gallery you may spend hours looking at Yan Von ik's painting arnoldi port pit and not see anything out of the ordinary in the foreground a couple holds hands and stares at the viewer but if you zoom in on the mirror on the wall you'll see two more people in the room art experts say the male figure in the painting has his hands raised to greet these two people seen in the mirror and that one of the figures is Von Ike himself oh and that's not the only Watermark the painter left above the mirror you'll see his flamboyant signature Yan Von Ike was here 1434 and speaking of people trying to sneak into their art Caravaggio the renowned Italian Renaissance painter left a little Easter egg in one of his famous paintings bakus this one is a bit difficult to spot in the half-filled jar in the bottom left corner of the painting there is a tiny self-portrait of the painter himself hidden amongst the liquid to see the image clearly one needs the help of sophisticated technology or at least a very efficient magnifying lens but it's there a male figure AKA Caravaggio with a brush in his hand fun fact the tiny self-portrait was first noticed in 1922 over 300 years after the painting was completed it was forgotten due to poor conservation to finish the trip you fly overseas across the Atlantic all the way to Chicago the enormous collection of the Art Institute hosts a well-known painting by Pablo Picasso the old guitarist this painting secret is so well hidden that it also needs the help of X-ray machines and super fancy technology but the results are worth it the readings show that Picasso painted the old guitarist on top of another unfinished painting we can clearly see the outlines and shapes of a half-drawn female figure that Picasso gave up on midw work the emerging artists of the time used that way of saving money quite often as canvas were expensive this was quite a tiring World trip wasn't it get some rest Sherlock of art if you look at it on the street you'll think a fire hydrant is about 3 ft in height but the actual size of the device used to provide water supply to Firefighters all over the world is twice as large that is if you count the rest of the hydrant which is hiding underground they're mostly red and it's not just a matter of Urban Design first of all they need to be of bright easily noticeable colors so fire firefighters can spot them fast when they need to the choice of color depends on how much water the hydrant can hold it can sometimes vary deing on the location but here's the breakdown a red fire hydrant can Splash 500 gallons of water per minute while an orange one at least 1,000 gallons green ones mostly process 1,500 gallons of water per minute and the most plentiful ones colored blue can generally contain over 1,500 gallons hey bowling fan isn't it super annoying when your bowling ball gets cracked turns out that most of them get damaged because of incorrect storage or spikes in temperature now come on and face it since it's already cracked a bit are you curious what's actually inside the bowling ball cuz I sure am let's have a look they mostly make the inner core of the ball of powdered metal oxides like calcium or iron oxide they mix them with some resin and Catalyst to harden the whole mixture so that light bulb shape you now see inside of the the ball is actually its heaviest part it also influences how your bowling ball rotates when going down the lane the same goes with spray paint cans when you shake it it makes a weird noise but what is that thing in there it's called a pee and it's meant to hold the paint mixture in place and maintain its shape they generally make it out of plastic metal or ceramic it basically acts as a whisk to make sure your paint is well mixed together before you apply it to your surface of choice ever wondered how soda bottles keep that refreshing Fizz for that long well they have a little plastic ring fastened to the lid they place it there to keep the gas from escaping and making the soda go flat even if you shake it around in your bag the whole day speaking of things we use on a hot summer's day wait wait don't put your baseball cap on just yet take a look at it for a minute and you'll notice there's a small button on the very top is it functional or is it just there for the sake of design way back when people started using Fabrics to cover their heads some say the button was actually functional since it's on top of the cap where the fabric panels come together the top button helps keep the cap Crown in one single piece now with recent advances in Fabric and pattern design the button is more of an aesthetic feature it's used to cover up the joint point of the fabric panels your cap might not have a button at all but don't you think a cap actually looks better with one cotton pads have two sides and if you take the time to look at them carefully they're actually different in texture just in case you've ever wondered why the textured side is for applying makeup and the even side is for removing it bookworms this one is for you dust jackets that come with a lot of hardcover books are not just meant to make your book look pretty they also double as a bookmark just fold the pages you've already read underneath the inside of the jacket and voila next time you reach out for your favorite shirt take a look at the top button hole it should be stitched hor horizontally and all the other ones are vertical turns out that the dress shirt was designed this way since the first and the last buttons were the first ones to unbutton throughout the day they then Chang the direction of the button hole to ensure the shirt would stay nice and fitted before you're ready to take it off these days we have so many variations of this awesome dessert that it's hard to imagine we've ever lived without it you can find different types of cookie dough ice cream or even chocolate chip cookie cake basically everywhere but the famous cookie wasn't actually invented until 1930 The Story Goes that a woman named Ruth Graves Wakefield Was preparing some chocolate cookies as she was waiting for some guests to arrive she soon figured out she was out of baker's chocolate a crucial ingredient for the classic cookies to fix things up she chopped up a block of semi chocolate thinking it would eventually spread out evenly throughout the batter given the heat of the oven things didn't necessarily go as planned but hey it's great they didn't because this is how she invented this modern dessert we now can't get enough of and speaking of popular snacks the potato chip is even younger than the chocolate chip cookie well at least historically there are many stories trying to explain how it was invented one of them goes like this a chef named George crumb based in New York put the chips together in 1953 he decided to try a different cooking solution when one of his customers didn't have nice things to say about his french fries he said there were too thick and kind of mushy then crumb came up with potatoes that were thinly sliced and fried until brown people absolutely loved the dish and they welcomed the first ever batch of chips with open arms ice cream anyone if the story is true back in 1904 at the St Louis World's Fair one ice cream shop owner ran out of cups to serve his dish so he fashioned a waffle into the shape of a cone and the rest was history okay IID admit it chewing gum like Treats have been around since the ancient Greeks so this one isn't particularly a revolutionary Discovery but the actual gum we buy today wasn't there until the late 1800s an American inventor named Thomas Adams wanted to mix together different chemicals to create rubber he tried and failed for that matter to play with chickle for his experiment but ended up fashioning this neat treat they still use chickle to this day to produce most chewing gums back in the 1800s their a man named John Baptist joli who worked in the fabric industry as a textile maker how he came up with this next invention that we use a lot these days has less to do with him and more to do with his maid The Story Goes that the woman accidentally knocked a kerosene lamp over onto a tablecloth instead of getting upset over the damaged fabric Jolly noticed that the substance actually made the material cleaner figured it out yet yep that's how the idea for the very first dry cleaner popped up a very neat accident if I do say so myself now this one I loved did you know match sticks were initially called friction lights or at least that's how their inventor a chemist named John Walker called them back in 1826 he scraped a stick coated in chemicals across his Hearth totally by accident one day and realized that they ignited and created a spark initially made out of cardboard they were then made using wooden splints and sandpaper back in the 1940s a man named Harry couver stumbled upon a chemical formulation that seemed to stick to everything it touched the scientific community at the time didn't look much into it as the formula didn't seem to have many applications back then it wasn't until 1951 that he looked a bit more into the formula and decided to repurpose it along with a fellow Eastman Kodak researcher named Fred Joiner they gave it a proper full name but you must know it by the shorter version super glue it also has many uses in security these days that it's hard to believe that we didn't come up with this one on purpose back in 1903 a scientist named Edward Benedictus knocked over a flask by accident he looked down and was amazed to see that the glassware had just slightly cracked but maintained its shape he was expecting it to break into a million tiny pieces curious about this hidden feature he looked into it and figured out what was keeping the glass together was a substance coating the inside of the glass TDA that's how Humanity came up with safety glass there's nothing better than a nice piece of butter toast for breakfast if we're not counting hot fudge Sundays but if you find it harder to spread out cold butter over your toast here's an idea use a cheese grater figure out the amount you need and Grate the product the process will also soften the butter making it easier to spread and you won't have to melt a too large amount of it in the process but still that hot fudge dried pasta comes in all sorts of different shapes and sizes for a reason that's because each type of pasta goes best with a particular sauce pasta shells for example are perfect with denser and chunkier sauces why because the sauce gets inside the shells making it easier to serve and eat the dish the ribbed outer surface also helps with covering the shells and the sauce if you ever end up burning your cookies ow you can save them with your trusty grater too just grate off the blacken Parts after carefully taking the cookies from the baking tray but be careful and wait until the cookies have cooled down also if you ruin their shape a bit you can always dip them in some melted chocolate ooh after the chocolate cools down you'll have perfectly shaped cookies although after it gets past your lips and Beyond does the shape of the cookie actually matter just saying if you like adding a lot of ingredients to your sandwiches but don't really appreciate it when the bread gets soggy there is a way to reduce the amount of moisture pick your sliced tomatoes or cucumbers and place them between two paper towels for up to 5 minutes after that you can use them also make sure to spread butter cheese or sauces like mayo or ketchup onto the bread first this will help you seal the bread and keep moisture at Bay some people think that the little white string that you find near an egg yolk needs to be removed before you cook the egg well I'm here to tell you that these strands are called Caza and you don't actually need to get rid of them they help keep the yolk in place at the egg Center a Kaza is not going to mess up the consistency or the taste of your food so removing it is completely up to you ever notice that most juice boxes come with two flaps one on each side those are actually handles manufacturers design the boxes this way to make it easier for us to hold them this way we don't end up squeezing the Box making the juice spill out now you don't need to be a baking Pro to know that you can use both white and brown sugar in your recipes but have you ever wondered what the difference between these two is it turns out that the only thing that sets them apart is that during production a small amount of molass is added to the brown sugar molasses is basically a sort of syrup you get when processing sugar cane it's usually removed during the refining process that's how white sugar is produced but if some amount of molasses remains in the final product we end up with brown sugar with its specific taste and darker Hue it's a good thing there are a lot of things you can put in your dishwasher apart from your dishes for example you can clean such things as as your Silicone oven mix or the knobs of some kitchen appliances like your oven or stove some kitchen sponges and reusable towels may be safe to clean in the dishwasher as well speaking of kitchen cleaning products there are a lot of things you can do with dish soap like deg grimming your patio furniture just add a bit of dish detergent to some warm water and use the solution to wipe down your outdoor furniture with a piece of cloth finally rinse it clean using your garden hose you can also use dish soap to get rid of greasy stains on your clothes be it pasta sauce or salad dressings hey sometimes we miss our mouths so just apply a little dish detergent to the stain and then rinse with water use non-colored soap for lighter clothes for more difficult stains let the dish soap sink in for a bit then throw the piece of clothing in the washer as usual and think about maybe getting a bib if none of the methods have helped you organize your closet and you're still overwhelmed with large piles of clothes there's a simple way that might be effective it's called the onein one out rule that means for every new piece of clothing you buy you need to get rid of one you already have that means you'll always be decluttering your space to make it easier to find something in your closet good luck keep your most used items at eye level this way they'll be easier to find and pull out when you're in a hurry those items that you tend to use less often like your evening clothes for example can stay on the shelves above or below your eye level you can make good use of Old Spice tins if you glue some powerful magnets to the inside of the tins they can double as magnetic shelves you can use them for all sorts of everyday items like kitchen pliers ice cream Scoops M or even Cutlery you can also place them on any metallic surface like your refrigerator door they'll blend in nicely with your kitchen magnets hidden in your laundry room there's a great tool for picking up head hair it sometimes works better than lint rollers take a dryer sheet and using some elbow grease you'll get rid of that dog or cat hair in no time it works on all sorts of surfaces but it's especially effective for upholstered furniture now if you don't like it when a door starts squeaking whenever you enter a room get a bar of soap and rub it straight on the hinges this will only help for a while though but it'll do the trick until you manage to get to a hardware store and you know buy some oil have you ever noticed that in some elevators there's a star next to the number of a specific floor no it's not to indicate where my office is it's there to point out where the nearest exit is and it's not always on the first floor it's most likely located on the floor closest to the street have you ever wondered why stop signs are red well back in the day they didn't actually have any particular color at all before the 1920s they didn't even have a standard ey shade in 1922 though someone came up with the Octagon but initially it was painted yellow all because the red coloring tended to fade out too quickly because of sun exposure so yellow turned out to be the best option it took another 30 years for a fade resistant enamel paint to be invented we ended up changing the color of the the stop sign back to Red after all it's still the best color if you want something to be easily noticeable do you know there's a type of rose that can grow taller than people according to the Guinness Book of World Records the tallest rose bush ever found grew in Vienna Austria it was a staggering 28 1/2 ft tall yes it arose to a great height in the same way we all have unique patterns on our fingerprints no two tigers had the the same set of Stripes it makes it easier for people working with this feline species to distinguish one tiger from another I'll bet you didn't know the White House has its own flower shop hidden in the basement of the building it's supposed to provide flower arrangements for all sorts of events that take place there it's probably no surprise that pizza has become an American staple dish despite its Italian origin people in the US love it so much that they buy $300 50 slices of pizza every second in the states man I'm not getting my fair share to manage the huge demand for this delicious dish around 177% of all restaurants in the US are pizzer Ras finally there's a way to make lemon juice without the seeds getting into your beverage try cutting the fruit in two and squeezing it with a pair of kitchen tongs the pointed end of the leemon should be facing down the juice will flow down but the seeds will remain inside the lemon ooh lemonade it goes well with pizza various types of cheese have holes for a reason for example swiss cheese is made with special bacteria that produce carbon dioxide as the CO2 is emitted it blows like bubble gum leaving tiny craters also known as cheese eyes then the cheese is cool down but the holes stay in [Music] place over 40 billion Oreos are made every single year it's the world's most popular manufactured cookie the geometric design stamped onto these cookies has the Nabisco logo the symbol of European quality surrounding the word Oreo William Turner created the chocolate cookie design we see today back in 1952 if you use reusable bottles you probably know that sometimes they smell even if you only use it for regular water water it still smells but it's not the water that smells it's the microorganisms in it if you drink water from a bottle the particles of your saliva and sweat stay in there those bacteria start to build up in the bottle causing the smell so if you choose reusable bottles make sure to wash them every day to prevent those bacteria from building up after washing let it dry completely before using it [Music] again not only are the jeans blue but the police officer uniforms as well the first official police officers appeared in the 19th century in London they were given a blue uniform to contrast with the red and white uniform that military workers had already been wearing two decades afterward the police force was adopted in the USA and they followed the patterns the uniform is still blue nowadays because it proved to be a good color it's not that visible in dark hours and police officers can observe things and people staying unnoticed also stains aren't that visible on dark material and well everyone knows that police officers wear blue and they recognized it so why change that baby carrots are tiny and unlike regular carrots wet not unlike baby humans baby carrots aren't some special sort of carrot they're actually made of regular carrots by cutting off the skin and outer layers and then polishing them to look that pretty the problem is they can't retain moisture a regular carrot retains some water inside because of the layers that lock it in once they're chopped out baby carrots can dry out easily so they usually sell them in bags with some water inside jeans have metal rivets and they're there from the very beginning Jacob Davis the man who made the first pair of jeans added copper rivets to spots where pants are more likely to rip flies and pockets to make them stronger today they have more of a decorative purpose since they are distinctive and traditional for jeans another special thing about jeans is those tiny pockets they have that seemingly serve no purpose well maybe it's true now but years ago when many Cowboys were wearing jeans the pocket was made specifically to keep a pocket watch there also back then a pair of jeans had just four Pockets that tiny pocket the watch pocket two big pockets in front and just one pocket in the back car headrests are all about comfort and detachable headrests are all about safety if you pull the headrest out you'll see two sturdy metal bars if you ever get locked or trapped in a car you can use the bars to smash the window and get out those little red spots you sometimes see after you crack an egg are nothing to be worried about tiny blood spots can be caused by a small run rupture in a blood vessel of a hen as it was laying the egg eggs with these blood spots are safe to eat but that spot can be removed if you want it won't affect the taste of the egg oh that's comforting hidden within the Toblerone logo of the mountain is the image of a bear standing on its hind legs about to eat that yodel over there no not really this is because bears are a big part of burn one of the biggest cities in Switzerland where the founder created the Triangular chocolate treat Toblerone is also a play on the Founder's family name tobler and the Italian word terrone for honey and almond [Music] nougat the space below a cup of noodles is there to protect the noodles during transport this technique is called a middle suspension not only are they protected better in their Styrofoam cup but it also helps those noodles soften more evenly and quickly even though you might have noticed that the hole on the barrel of ballpoint pens has no purpose it does it's called a venting system which helps the ink flow more smoothly this way an even amount of air pressure is created inside and outside the pen allowing the ink to flow into the point easily it's not an accident that soy sauce bottles have two spouts the sauce is liquid and it flows out of the bottle pretty quickly Once you turn it over most Asian food lovers will admit they've spilled it at least once in a lifetime that's why nowadays restaurants prefer serving soy sauce in special bottles that have two spouts this design allows you to control when and how much sauce will come out just put your finger on one spout while you pour the sauce through another if you press your finger tightly to the spout the sauce will stop flowing and if you remove your finger it will flow again and please do not remove your finger in a restaurant it will freak everybody out you've probably noticed that train and bus seat are covered in Fabrics with weird patterns any idea why they use these patterns to cover any germs and stains on the seat oh boy the brighter the color and the more patterned it is the harder it will be for a passenger to notice any stains and get grossed out also the patterns are usually so ugly that no one even wants to look at them for long enough to spot any stains so yeah the pattern is there to make you look away and if you look to make it less noticeable no bus will ever have plain white seats that's a guarantee the midle tab on soda cans can be flipped around you can slip a straw in place so you don't have to hold it up your mouth this stay on Tab replaced the pull ring tab created in the early' 60s you remember those don't you those could be quite sharp and easily discarded where they could be a menace for others now you can pop your straw straight into one also means you can produce some Bubbles and make a mess like a 3-year-old sometimes when you purchase an article of clothing you receive a plastic baggie with an extra button and a Swatch of fabric while the fabric is clearly used to patch holes it can also be used to test the effects of various cleaners on certain surfaces it's handy too to test wash Cycles before using them to wash the whole garment escalators have those fluffy black brushes for a similar reason that some have yellow lines on their steps to try and deter people from getting too close to dangerous places people don't always take notice and sometimes clothing can drape close to the point where the step meets The Edge or skirt the brush is a little barrier to help prevent this from happening they can also catch bits of fluff and prevent other small things from falling down into the gaps those takeaway containers most associated with Chinese restaurants are designed to not only carry your food home but to store it in the fridge they double as a plate as you can eat straight out of them and don't have to worry about dirty dishes yay they were actually patented way back in 1894 to transport freshly Shu oysters and were known as oyster pales they were later adapted to use as leak proof containers for [Music] food ever wondered why coins have those little ridges along the edge it's a leftover from earlier times when they were worth more counterfitters could easily file the edges off to sell as gold or silver coins to make some profit The Ridges were created so it was much easier to tell which of the coins had been altered it's not needed today but the coins still have that altered style all crackers and some cookies have holes to make sure the final product has the right texture these teeny tiny holes allow steam to escape so your crackers and cookies won't snap if it weren't for these holes also known as Dockers steam would build up inside the tree and the final result might have been scrumptious but it would have been rather oddly shaped dogs like to walk in circles before snoozing because they inherited this Behavior pattern from their ancestors there were no special doggy beds back then so most pooches would have to push down Tall Grass to make a sort of snoozing spot plus as a bonus those movements scared off all the critters lurking in the vegetation Donuts are ring shaped for a similar reason if they hadn't had holes right in the center the dough there would have always been undercooked by the way they're often associated with the police because back in the 1950s dut shops were among the only places open L they were a perfect place for police officers to grab something to eat and even deal with some paperwork during the night shift your jeans are blue on the outside and white on the inside because of a smart way to weave the fabric the warp thread is dyed while the weft thread has no color it's just white this way manufacturers reduce the amount of dye needed for each piece of clothing and they're still dying to make the [Music] jeans you just spent the entire morning running errands up and down the street and you finally stopped to treat yourself to a cup of coffee you enter the nearest coffee shop place your order and notice that actually you really need to use the bathroom it's a regularl looking public one with multiple stalls as you pick yours the one in the middle you get inside and your mind starts to wander why on Earth do bathroom doors have a/ in gap between the door and the lock and why on Earth do they have a huge gap between the door and the floor can we have a drum roll for this moment please well my friend there is not only one specific reason why public bathroom doors have so many gaps in them but rather several public toilets are designed to make people spend as little time there as possible you aren't supposed to feel comfortable or at home so the design would have to reflect this notion here come the gaps in some bathrooms gaps are so big that users may even feel self-conscious about doing their business out of preoccupation that the rest of the people standing in line will see them then there's the matter of pricing making custom doors can be a heavy burden for the people building public toilets this would mean understanding exact measurements so that doors would always fit the mold of the Stalls it's supposed to be installed into now not all the gaps in public bathrooms are necessarily the same size they may vary even if this variation is small and often unnoticeable so these gaps actually help to reduce the margins of errors and to turn production more coste effective for the people financing them in case a door comes wider or more narrow than it should the Gap regulates the difference es and allows for their installation anyway there is also the case of air circulation the last thing you want to do in a public bathroom is to trap odors so you need a little space under and between the doors to allow the air to flow finally the gaps are a big safety measure it can always allow for people on the outside to see if someone inside a stall isn't feeling too okay and maybe need some help and what about that extra hole in the upper part of the sink it has has a name in everything the Overflow hole and it's designed to keep the sink from flooding so in case someone forgets and keeps the faucet going for too long or the sink gets clogged and water can't drain down from the main drain hole the Overflow hole comes in to save the day let's say it buys you a little time before you have the entire bathroom floor flooded have you ever noticed how satisfying closing the door of a car can be car manufacturers devote a great deal of time to designing these sounds Studies have shown that they create a perceived sense of quality in the buyer it all begins with the primary material while older cars used to be made with heavier materials car doors nowadays are produced with lighter tin which can make a rather unpleasant metallic sound once you shut them closed so car companies employ sound Engineers to ensure that there is the exact amount of foam mats and tin in a car's composition to make the most comforting sound possible and what about those tiny dots on the top of your car's front window the pattern of these little black dots minimizes distractions for your eyes this black part also known as frit normally gets warmer than the clear Parts which prevents the windshield from deforming and no the tab under your rear view mirror is not made only for the purpose of hanging fluffy dice or aromatic pleasing air fresheners it's actually a switch that allows you to adjust the position of the mirror depending on the time of day flip it one way and it's the daytime driving mode flip the other and you're ready to drive safely during nighttime as it tones down the glare coming from headlights of the cars behind you next time you head out to the supermarket make sure to keep this in mind in case you don't have a coin to unlock these shopping carts there is a well-kept secret that can help you out if you have your house keys on you check for a rounded key head if you happen to find one try using it to unlock the card it should fit perfect in there we're placing the need to carry coins around because if we're being honest who still has them elevators if you want to ride them on your terms and your terms only make sure to try something out most elevators have a secret button combination you can use to skip all the other selected floors and go directly to the one of you are choosing this might work out especially on those days when you press 13 but you wanted to press 33 on most elevators this works once you simultaneously ly press the Clos door button together with your floor number this should help you get to your floor without stopping some elevators require you to double press the selected floor numbers as double pressing will often cancel the previously made request while other elevators require you to hold the open door button and then double press the buttons of the floors you'd like to cancel now to stay out of trouble it's best not to cancel the fls of the other people in the elevator they won't take it kindly also keep in mind that there are elevators that might not have this function now for honey lovers out there go ahead and raise your hand if your pot of Golden Honey is crystallized know that it is actually a good sign crystallized honey means that it hasn't been pasteurized which means better product quality with a decrease in temperature the natural ingredient of Honey also known as glucose will make it crystallize now try making the best of it to add some texture to your oatmeal or toast add a layer of crystallized honey and enjoy Nature's sugar and if you don't like crystallized honey plop it in the microwave for a minute or two ah winter and fall you know what this means right Sweater Weather but there's nothing more annoying than wearing your beautiful wool sweater and itching yourself all the way through it actually I can be more annoying than that but let's talk about itchy sweaters to keep this from happening again here's the secret turn your sweater inside out and soak it in cold water water add 2 or 3 tablespoons of vinegar and let it sit for a while then drain the water now while the sweater is still wet massage a generous amount of hair conditioner into the fibers of the wool after letting it soak in the hair conditioner for about 30 minutes gently press the excess water out of the wool and leave it to dry flat on the towel there you go no more itchy sweater any fast food restaurant you go to will hand out small paper cups for customers to to fill with their ketchup mustard or barbecue sauce but if you're eating some chicken nuggets or trying to dip your burger into the cup there's always that bit of sauce that seems impossible to reach next time try unfolding the cup it'll turn into a small paper plate and this way you'll get all the ketchup you poured in the first place padlocks used in outdoor environments should be clean and lubricated every 3 months regular lubrication will help prevent padlocks from freezing in cold weather conditions look for the tiny hole on the bottom of the lock then pour oil into it and there you go it opens again one thing we often neglect is a point in an ointment cap these pointy surfaces were designed to help us break the tin foil protection of the ointment
