were square-shaped slabs of stone unfortunately these were prone to accidents if they weren't placed properly a square cover could slip through the square hole diagonally out placing a round cover eliminated this problem a circle cover won't slip inside because there are no angles a tomato isn't technically a vegetable but a fruit banana trees aren't related to palm trees or trees at all they're herbs banana is considered an herb because it never builds a woody trunk the way a tree does instead it forms a succulent stock like lemongrass or its cousin ginger you can call them berries as well the golden gate bridge color wasn't meant to be the orangey red that it is today the bridge's original color was suggested to be many other colors such as black with yellow stripes or even candy cane to make it visible for passing ships and aircraft especially in the frequent san francisco fog but when the steel arrived covered in an orange primer to protect it from rust the architect

the mountain is the image of a bear standing on its hind legs about to eat that yodler over there no not really this is because bears are a big part of baron one of the biggest cities in switzerland where the founder created the triangle chocolate treat toblerone is also a play on the founder's family name tobler and the italian word tyrone for honey and almond 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 now even though you might have thought that the hole in the barrel of a ballpoint pen had 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 one of the most recognized logos in the cycling world has a hidden item in its famous logo inside the tour de france name a cyclist hides in the o u and r why keyboards have markings if you look at your computer keyboard you'll see two ridges on the f and j keys those help you position your hands and find the correct keys without looking the trend started decades ago when people started taking typing courses learn to use all 10 fingers while positioning their index fingers on the f and j keys why you yawn now folks used to believe that people yawn because their body needs to take in more oxygen but that theory was revised in a 2014 physiological research scientists studied 120 individuals and found that yawning happened more in the summer and less in the winter it's the brain's immediate response to regulating its temperature when it gets hot yawning also helps you wake up the movement stretches your lungs and let your body flex both the joints and muscles another study explains that contagious yawning in humans has to do with empathy why you snore when you're sleeping and not when you're awake well that happens because air can't move freely through your nose or throat that causes tissues to vibrate ensure dinosaur-like sound it doesn't happen when you're awake because the muscles in your throat hold the airway wide open to allow smooth airflow but during sleep those muscles relax and your airway shrinks why taxis are yellow at the dawn of this mode of transportation john hertz the founder of one company in new york purchased several dozen used cars for his business to make the vehicle stand out he painted them yellow after reading a study by the university of chicago which said this color was the most visible from a distance in europe yellow cabs had already toured the streets but their career was short-lived however in 2013 green painted cabs appeared in the city through gps analysis the taxi commission found that some areas in new york had limited access to taxis so green vehicles called borough taxis picked up passengers from those left out areas to fill in the gaps why do calculators have solar cells the first solar calculator hit the shelves in the late 1970s back then scientists began experimenting with cheaper solar cells than the ones used on satellites calculators were among the first products to have them to boast how little power they needed to work in the 1990s companies announced that more solar power goods would soon come out but they never did the technology moved to larger products such as lights and highway signs why do some sport coats have elbow patches originally sport coats were made to be worn outdoors for sports they had pieces of fabric in the elbows because it was easier and cheaper to replace just those parts than buy a brand new coat later university professors and teachers began wearing them the patches came in handy when the elbows rubbed against the desk and riding board traditionally they were made of leather suede or heavy wool but today the patches are for aesthetic purposes why notebooks have page margins in the olden days paper was a sweet treat for rats mice and other rodents to avoid losing valuable information from books and notebooks people began leaving empty spaces around the edges that's where most of the damage occurred later when notebooks were printed the margins stayed for notes dates and comments in books the spaces became a norm for both printing purposes and to prevent the information from being lost because of regular wear and tear why toothpaste tubes have color bars on them there's a myth that the colored rectangles have something to do with the ingredients of the toothpaste [Music] but the color bars are there in fact to indicate to the machines where the package must be cut folded and sealed different color codes are used for different packaging machines i like the other story better how play-doh was created when this putty first came out it was intended as a wallpaper cleaner that removed soot from the open fireplace but soon vinyl wallpapers came out and the demand for the product dropped someone in the inventor's family read a newspaper article about making crafts using the cleaning putty they tested it with some kids in the kindergarten they loved it and then the product was rebranded as the beloved play-doh why post-it notes are yellow now their inventor was trying to create a very strong long-lasting adhesive but ended up with a low-tack glue instead while trying to promote his invention without success his colleagues suggested using it to temporarily stick bookmarks in his books and bingo post-it notes appeared the yellow color occurred coincidentally because the lab next to them only had yellow scrap paper now here's a trick instead of putting the box grater vertically on top of a plate put it horizontally with no plate underneath of course this way you won't risk scraping your knuckles because only your fingertips will eventually touch the grater when you reach the end of the process also it gives the grater more stability when otherwise you'd have to balance the grater or even hold it in the air with the other hand when you're done or when there's just too much grated stuff on the bottom wall of the grater simply turn it on its side to pour the contents into the bowl or plate flowers in a vase would stay fresher for longer if not for the bacteria that breed in the water since copper has some antibacterial properties dropping a penny into the water will help keep the microbes at bay and let you enjoy your flowers for that little bit longer an easy way to check if your bed linen has dried completely is to put a small mirror in between the layers for about five minutes if the mirror has steamed up when you pick it up it means the sheets are still a bit damp let them dry until the mirror stops getting cloudy a damp bed is a lovely breeding ground for fungi and bacteria okay i'm in if you have a not very healthy habit of eating in front of your computer you'll be surprised at how much crumbs and grime there is inside your keyboard now you can just turn it over and shake it vigorously of course but that's not very good for any piece of tech you know so instead take a post-it note and run its sticky part over the keyboard it will collect the little pieces of trash like magic even a better way to do it though is to take a slime and stick it to the keyboard then take it away squeeze it and stick again in another part the slime will fill the entire space between the keys and its sticky properties will let it gather every little bit of garbage separating egg yolks from whites is easier using a plastic bottle break the necessary number of eggs into a bowl and then take an empty plastic bottle and squeeze it hold the bottle over the yolk and release it'll pull in air and the yolk together leaving the white in the bowl repeat with the rest of the yolks and you're done and that's no yolk if you're tired of spitting out the stones when eating cherries or want to make a cherry pie push the stones out with a straw also many garlic presses have a special tool on their handle that can be used exactly for that cleaning a blender can be a nuisance if you do it manually instead fill it with hot water and add some liquid soap or detergent then run it for about 10 seconds rinse it afterwards and it's clean plaster walls can crumble flake and spread dust all over the floor when you hammer nails into it cut a strip of masking tape and stick it to the place you want to hammer a nail in the tape won't let the plaster crack and crumble leaving the hole neat and clean small scratches and dents on wooden furniture can be removed with some toothpaste or old walnut for toothpaste rub a pea-sized amount of it into the scratch until it's gone then wipe the leftovers with a damp cloth for a walnut take a half of that brain-shaped nut and rub it into the dent then rub the area with your fingers and buff it with a soft cloth this will help the wood absorb the oil from the nut making the scratch sealed and gone the sticky residue on jars left after you remove the stickers won't be easily removed by water and detergent so take some vegetable oil instead soak a cotton pad in it and wipe the sticky surface let it sit for a while and then wash the oil away together with the residue if you can't comfortably reach the wick of a candle with a lighter hey take a stick of spaghetti light up its end and you'll get a burning stick that's easy to use for hard to reach places now next time your razor blades getting dull try rubbing it backwards on a pair of jeans for regular upkeep not while you're wearing them of course make sure you keep the blades dry too or even kept in mineral oil that'll stop them from rusting keep all those jelly ketchup peanut butter and mayo fresher for longer in your fridge by turning the contents upside down this creates a partial vacuum inside the container helping prevent mold growth storing ice cream upside down will prevent freezer burn too to bring your permanent marker back to life simply put a few drops of rubbing alcohol into the felt material inside and shake once the felt absorbs the rubbing alcohol for a couple of minutes the marker will be almost as good as new now don't keep throwing away lettuce that goes black too quickly covering it with a dry paper towel and then placing it in an airtight container will help it keep fresher for much longer this goes for any leafy greens you've got leftovers of that sharpish bit sticking out of the cap of your favorite cream is there for a reason these tubes are usually sealed with foil so unless you love breaking your nails trying to open them just flip the cap over and push your bobby pins might not stay in place if the grooves aren't facing the right way they should always be on the bottom close to your head still coming loose well put a squeeze of hairspray right onto the bobby pin before you put it in your hair now your cotton rounds pack has those strings on it so you can hang it on a handy hook in the bathroom but there's no need to loosen and tighten it back up every time check out the bottom of the pack it has a perforated line tear it open carefully and you're good to go soda bottles are always filled in such a way that there's some space between the liquid level and the cap that's because these drinks contain carbon dioxide this gas can expand if the bottle gets heated if there's no air gap in the bottle it'll break because of the pressure building inside also when you open your drink the gases go out in the form of bubbles and the drink is likely to overflow the gap helps with this problem too except if you shake it up first then open it now i've never done that there are sounds most people can't stand like the sound of a fingernail on a blackboard or someone scratching a window such noise irritates the amygdala that's a small part of your brain controlling your emotions including fear and survival instincts some cheeses have holes in them they're called eyes these eyes are made by bacteria used in the process of production when cheese is almost ready these bacteria release carbon dioxide and this gas forms bubbles that later become the cheese's eyes see cats knock different things over because of their hunting instincts your cat is simply checking whether the thing is alive or not or it might want your attention cats are smart and know that humans come very fast when something is broken when the pizza dough is ready it gets manually spun in the air this process removes lumps and creates its circular shape it's more convenient to bake a round pizza this way it gets heated evenly plus it's easier to cut around pizza into equal parts there have been reports of raining frogs fish and other unusual stuff dating back to ancient civilizations strong winds such as those in a tornado or hurricane sometimes get so powerful that they can lift up a school of fish or frogs and rain them somewhere miles away lighting is never a triangle straight line or circle it always has a zigzag shape lighting is an electric current and it always takes the path of least resistance air is uneven and irregular containing dust particles gases and other substances so lightning just seeks the best way through flowers have different colors because of the color pigments they contain but there are other factors for example the amount of light they receive while growing or the temperature of the environment around them even the ph level of the soil can have an impact on flowers coloration by tilting their head dogs try to understand all you're saying correctly it's the way to adjust their ears to the sounds they hear it may also be the way to show their empathy to the owner or they got something stuck in there tickling is bound to cause a laughter reflex but nothing will happen if you tickle yourself that's because there will be no element of surprise your brain knows what you're going to do barcodes speed up the purchasing process if a barcode consists of 12 digits the one on the very left is a system identifier for example two means it's a randomly weighed item three is used for products related to health the next five digits identify the manufacturer and the following five are the products number the last one is the check digit scanners needed to make sure they've read the code correctly the song is bound to get stuck in your head if its music is simple the text is repetitive and short and the rhythm makes you move another reason you might have an ear worm is that you hear some songs too often and your brain can easily detect them 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 very pale and don't print them with age your hair loses its natural color it happens because keratin receives less pigment as people grow older the pigment cells in their hair follicles gradually vanish and hair becomes gray some time passes and no pigment is produced at all that's when hair turns white trees stop growing at a certain age it might be because when a tree reaches a particular height it gets difficult for it to pull water from the soil because after that it needs to pump it all the way to the top and that's when gravity comes into play some trees like the baobab start growing out instead of up once they reach their full height your own body makes mosquito bites swell and itch a mosquito breaks your skin your immune system perceives the insect saliva as a foreign substance so it starts a special reaction to flush the intruder out of your body a compound produced by the immune system called histamine makes the blood flow faster around the bitten area and it causes the swelling the histamine also sends a signal to the nearest nerves which makes the bite itch geese usually fly in a v-shaped formation to conserve energy and make sure none of their team members get lost you can't hum while holding your nose trust me during humming you exhale air but when both your mouth and your nose are closed the air can't escape the longer you can hum like this is two seconds then you'll have to open your mouth and catch your breath road and construction workers are usually dressed in orange because the bright orange hue is visible even in bad weather it's the most effective color to attract attention and alert people no wonder lots of safety jackets and traffic cones are orange as well modern day perfectly round coins used to be shaped randomly or have no shape whatsoever in the past but dishonest people stole valuable metals the coins were made up by chipping their corners off of course it was illegal to prevent this kind of fraud they invented round coins after that it instantly became obvious when the coins had been fiddled with what about those metal rivets most jeans have they're more than a design choice they were added to protect areas that experience the most strain such as pocket corners and the base of the fly the rivets hold the fabric together even when it's being stretched and pulled during work and since we're talking about clothing have you ever wondered about that tiny fifth pocket at the front of your jeans well first of all it isn't really a fifth pocket originally jeans were made with four pockets including that little one in front the fifth pocket is actually the one on the back left which was only added to jeans in 1901 the little pocket though was important a long time ago cowboys needed to keep their pocket watches safe while riding out on the range that pocket kept the watches protected but also handy and then people became so used to it that jeans just look weird without one another strange holdout from a bygone day is that stitched v on the front of some sweatshirts what if i told you that those exact stitches hold the whole shirt together well then i would be lying and i never do that but back in the 1940s this v was very useful first the v-stitch was initially used to add a patch of stretchy ribbed fabric to the shirt so that it could fit over our big heads more easily secondly these shirts were specifically designed for sports so the v included an additional piece of fabric to absorb the sweat that would build up during a game or a workout as stretchy fabric became readily available and better at handling perspiration the v lost its traditional value but like the tiny jean pocket it has continued as a decorative feature a reminder of our big headed ancestors who apparently only sweated just below the chin but moving on one place you won't find many people sweating is the golf course you will see quite a few fashion disasters sure but sweat not so much golf was invented around the 16th century in scotland but then the ball was perfectly round and smooth over time the ball would become dented from use and at some point golfers discovered that these imperfections actually helped the ball fly farther dimples were added on purpose in the 1900s when it was found out that they reduced the aerodynamic drag that slowed down a smoother ball and the dimples made the balls easier to control and no not all golf balls are created equal the number of dimples can range from 300 to 500 with one company producing a ball with over a thousand little dents wow a little overboard eh need a quick refreshing drink after a round of golf juice boxes created back in 1963 are very convenient but why do they have these large triangular flaps on top their lifted flaps act as hand grips this stops you from accidentally squeezing a full box and spilling juice all over the place like on your favorite t-shirt or the new couch now when you're done golfing grab your backpack with that leather diamond patch with two vertical openings it's commonly referred to as a lash tab but i much prefer its other name pig snout i mean it certainly looks like one you typically find these pig snouts on patch used by hikers and climbers the diamond is a place to tie any extra gear that they need to carry like boots cooking equipment or sleeping bags but these lash tabs are also becoming more common on smaller backpacks they're a nod to the past but just as useful attach your running shoes to one next time you head to the gym keeping those stinky things away from the rest of your clothes now i'm sure you're a great driver but for years you've probably been neglecting an important safety feature right in front of your eyes that rear view mirror has a small tab located at the bottom center it's high time you started using it when this is flipped forward the mirror is in day mode providing a strong reflection of everything behind the car flipping the tab backward changes the whole situation to night mode this reduces the brightness of the headlights behind you resulting in a safer drive another cool car tip if you're borrowing from a friend using a rental or have the memory of a house plant cars feature a handy indicator to let you know which side the gas tank is on it's a tiny arrow next to the pump icon that points either left or right where the arrow points that's where the gas tank can be found and that's one less thing you have to remember okay off to the grocery store a regular shopping cart has a useful feature you might have been overlooking carts usually include loops in the metal frame often behind the child seat as you bag your groceries hang the ones with fragile or squishable items like eggs or bread on these loops now they're out of harm's way when you toss that giant watermelon into the cart later when you're unloading your groceries do yourself a favor and grab that box of plastic wrap you know the one that is impossible to unroll without the whole tube coming out while the plastic wrap sticks to itself check out either end of the box and you'll see small tabs that you are supposed to push in this helps to hold the roll in place so you can easily pull the plastic wrap out without all the fuss aluminum foil boxes also have these tabs now that you can finally use that plastic wrap try this appealing hack separate that bunch of bananas and cover each stem in some plastic wrap the stem releases a gas called ethylene when it reaches the rest of the banana it encourages the fruit to ripen and turn black if you wrap the stems your bananas will last longer so anyone who's ever licked a nintendo switch cartridge will confirm they taste bad and the bitterness stays in your mouth for a while you can thank denatonium benzoid for that it's one of the most unpleasant tastes out there and carts are coated with it so people and pets won't accidentally swallow them before we had better storage for books and records they'd be kept in places where mice and rats could easily munch on them but they'd only chew around the edges margin lines were put there to keep the writing away from the edge so you don't lose any important information to the rodents take a closer look at your red solo party cup the lines around it are from measuring liquids the bottom line equals one ounce the second is five ounces and the top line means you have 12 ounces in your cup you've probably been storing your peanut butter wrong your whole life the trick is to keep the jar upside down so the oils don't come up on the surface sometimes screwdrivers are meant to work together with wrenches it helps especially if you're working at an awkward angle just slide the wrench onto the screwdriver's handle it fits snugly and next time you need to put in a hook screw put the screw eye into your drill the round end will hold the hook in place and the project will go a lot quicker if you don't have a screw eye on hand use a key the black grating on your microwave door is called a faraday shield it prevents the rays from escaping the oven but get this it can also block phone signals so if you're tired of endless calls and texts put your phone in the microwave just don't turn it on if you get a box of chocolates with a little dent in between the holes for the candy push it the chocolate surrounding it will pop right out of their snug little compartments you shouldn't have to push the sweep from the bottom though this weighs much quicker you try to pull out some aluminum foil but the roll keeps coming out of the box it's not supposed to push in the tabs on the sides of the box they'll hold the roll in place don't throw away those little silica gel packets you get in new shoes and bags you can use them to absorb moisture in any place it collects foam get wet put it in a plastic baggie with a silica gel packet it'll get the water out throw one in your shoes to keep them smelling fresh tape one to the lid of your pet's food container to keep mold out you can even put a packet in your tool box to prevent rust women's shirts oddly have buttons on the left even though most people are right-handed it comes from the times when upper class ladies would have hand maidens dress them the wearer's left became the dresser's right so it was easy for them pants creases have their story too to squeeze in as many goods as possible to transport them folded pants got heavily pressed it was next to impossible to get rid of the resulting creases so why not make them fashionable there's a loop on the back of your button-up shirt so you can hang it without it getting wrinkled and fun fact back in the day it showed your availability young guys used to cut those loops off once they started dating someone doorknobs are usually made of brass bronze or some other copper alloys for a reason they have an anti-microbial effect they get rid of germs pretty fast within a couple of hours but you still have to wash your hands after touching doorknobs rough edges on the sides of coins come from an ancient practice the weight of coins made from precious metals used to show the real value of the coin people would shave off the edges melt them together and make new coins from what they collected to avoid that ridges were added so you could see if a coin had been tampered with toothpaste stripes are no more than a marketing trick in the 70s a leading toothpaste brand introduced a blue stripe to show that their product had double the action solid white toothpaste have the same functions though those blue bristles on your brush are a lot more helpful than toothpaste stripes when they fade it's time to change your toothbrush take the lid off your to-go cup and turn it upside down you'll get an instant coaster it has a rim on the inside that your cup bottom fits into perfectly if you prefer your soda in a bottle check out the little plastic disk in the cap it's there to keep the gases in your carbonated drink without it you just have syrupy brown water detachable headrests in a car can be used to break the windows in case you get stuck in just don't go swinging at the window though you could hurt yourself slide one of the prongs in between the pane and the door pull the headrest back towards yourself and the window will shatter don't forget about the tab on the bottom of your rear view mirror pull it back during nighttime driving if someone's behind you their headlights won't be blinding pull the tab forward again for daytime driving the spoon to your mcflurry looks so weird with all those tabs because it's actually fitted to the ice cream machine to stir your tree bath foam isn't only for fun or a nice smell the bubbles keep your bath water warm for longer the air inside them acts as insulation but it only works for acrylic bathtubs ones made from metal lose heat really fast either way small holes on your headphones let the air circulate which is a must for good sound quality wooden hangers may be bulky but you should still opt for them over plastic or metal hangers made from cedar keeps moths away the oils in the wood are a natural insect repellent you can also add some dry orange peels to your closet to keep the bugs away now who hasn't gone through the confusing task of having to measure how much pasta to cook for one serving well here's the solution the holes in the center of pasta spoons they were actually made for measuring the exact amount of dry pasta you need for one serving if you try stuffing wet cooked pasta through it well good luck with that on a similar topic have you ever wondered why pen caps have holes in them maybe you thought it was a design feature to regulate air pressure but in reality these holes have a much simpler and more important function to reduce the risk of choking now lots of people love to bite on their caps and this tiny hole prevents them from choking in case they accidentally swallow a cap and it gets stuck in their throat for kitchen lovers there's a hidden secret right in front of your eyes that can change your life think pants now think handles right they have holes in them as it turns out these holes were designed to hold the spoon you're using for cooking and instead of dripping sauce all over the stove or your kitchen floor you can place the spoon in the hole and let it drip the sauce directly back into the pan speaking of everyday items and i was most door knobs are made of brass because this material makes them naturally germ free unlike plastic ones brass door knobs are kind of magical they can disinfect themselves without you having to clean them neat right have you ever noticed that at the bottom of a measuring tape there is a little dip you can find it in that metallic part you need to pull on to measure something well that dip is actually the exact size of a regular nail it was designed for people to place the tape on top of a nail and use it as a support while they stretch the tape well i can't wait to try it out for myself as for the margins in your notebook they were invented to protect people's notes from mice now the mice weren't copying your answers for the math quiz actually there were times when people had to cohabitate with rats and mice that often chewed on paper so to prevent information from getting completely lost people created margins this way texts were moved closer to the middle of pages and remained unharmed by rodents perhaps this is where to digest information came from and what about those tiny holes at the bottom of airplane windows they have an extremely important function of regulating the air pressure inside the cabin in other words they help planes fly high up in the sky big responsibility right by the way tray tables on an airplane are the germiest places inside the entire cabin studies showed that the trays had eight times the amount of germs on the toilet flush button now how about we cut a commercial airplane in half and see what's inside well it would look more or less like this rows of seats on top and everything else that needs to be stored at the bottom i'm talking about passengers luggage emergency supplies parts of the wing system and so on moving on to bowling balls yes i know it's a clumsy transition anyway have you ever wondered what the insides of a bowling ball look like if you have cut a professional ball in two you'll see a familiar shape look closely do you see it doesn't that look like the logo of bright side anyway professional bowling balls are different from the ones in your local bowling alley that's because they're designed to make fancy moves they actually have some really complex engineering inside their shape to help skilled professionals get more strikes the weight of professional bowling balls is designed to be projected inward as they travel down the bowling leg this makes it harder for them to get into the gutters on the sides of the lane speaking of balls let's take a look inside a baseball to make it light and aerodynamic producers use several different layers starting from the core we have a cork center enveloped by black rubber then there's a layer of red rubber followed by two or three alternating layers of wool yarn after that there's a visible white leather cover and that beautiful red seam on the side stitching it all together and what if you had x-ray vision and managed to look inside a human bone ooh spooky i'd say what caused most attention is this spiderweb like situation at the center of the bone in reality it's a highly condensed and complex structure of nerves that you have inside your bones aren't you lucky now i've got a riddle for you what is round can be found near the ocean and looks like an aerial view of the guggenheim museum in new york city the one that's made almost entirely of ramps if you said a nautilus shell hey then you guessed right a nautilus is a shellfish whose house you can find in countless souvenir stores near the beach it's made up of two layers a matte white outer layer and an iridescent white inner layer and if you were to cut it in half it would look very similar to the insides of the guggenheim museum
