This Is the Reason Why the Doors in Public Toilets Don't Reach the Floor

hi everyone have you ever figured out the true purpose of a thing after you've used it for different purposes for years or considered it's utterly useless turns out that many ingenious inventions don't get the credit they deserve and sometimes people don't appreciate them at all today we will tell you about things that you've probably used incorrectly before watching this video or simply didn't know about their true purpose let's get it on doors in public toilets you've probably noticed that the doors of the cubicles into public toilets almost never reach the floor maybe it's even irritated too that's a private space after all but believe us this was done for a reason in fact this marvel of engineering has several purposes firstly it helps visitors to understand whether the toilet is occupied or not and it saves time when janitors are washing the floors and secondly and more importantly this gap can be used if the toilet doors get jammed or locked from the inside this is not to mention that the short doors are simply cheaper than the ordinary ones another interesting fact is that most toilet doors open inward which can be very inconvenient if there's not enough space and you have a bulky backpack with you but this was not designed in order to annoy you the doors open inward in order to not block the corridor and avoid injuring of the people after all they can't predict when the door near them will open arrow on the gas gauge we bet that even the most avid car enthusiasts don't know what we're about to tell you you may have thought that this barely noticeable arrow is a completely useless thing but like any car parts it has a purpose the arrow indicates which side of the car the gas tank cap is on of course if you are the owner of a car this information will most likely seem useless to you but seeing our fast car sharing is running across the world at the time of refueling this can be very useful since he rents a new car each time extra scrap of cloth let's admit it that nobody uses these bags with an extra piece of cloth and a button who will actually sew up the torn patches nowadays although hold on a second is this their real purpose turns out it's not in fact they let you know the nature of the textile material used so that you don't wash it in a way that can potentially ruin your entire clothing just imagine how many white t-shirts will be saved thanks to this life hack pins on PVC windows have you ever noticed a strange pin on the side of windows few people know it's designed to switch between winter and summer modes of your windows these modes differ primarily in the magnitude of pressure exerted on the frame by the way because of improper control of the regime's more precisely due to its absence people often experience drafts in the apartments in winter the mechanism that helps to adjust the seasonal mode can be moved up and down with the help of improvised tools for example a simple allen tool using this tool you can modify the force with which the pin holds the frame small pockets in jeans we are so used to having a small pocket on our jeans that we don't even think why we need it in the first place there are many theories about it though some believe that a lighter or a pack of chewing gum fix perfectly into this pocket while others keep coins or builds in there but in reality this pocket was invented by the legendary Levi's company for pocket watches it's not surprising though at the end of the 19th century when the first model of these jeans was designed people still didn't wear a watch on their hands using small chronometer on a chain instead rivets in jeans another interesting fact about jeans is the purpose of the rivets yes they also have their own function and it's not just purely aesthetic the fact is that jeans used to be popular among workers and miners due to constant physical labor the fabric was subjected to daily stress and stress tension in order to protect work clothes retiring the manufacturers decided to use rivets the blue end of the eraser since our school years we know that the blue end of the eraser is used to erase mistakes made with our pens although to be honest it barely works and no wonder the blue end is actually meant for erasing pencil marks on heavy grades of paper or dark marks the soft end is useful for light grades of paper which the hard gritted side would tear apart no one understood the intent of the manufacturers and at some point they just gave up and began to mark the hard end of the eraser with a small image of the pen a cylinder on a charging Court many cords for charging laptops or cameras have a small cylinder that looks like a plastic barrel but what does it do after all this is hardly just a decorative elements in fact it has a very important function in fact this is a high-frequency filter that eliminates interference from the power cable such interference may occur for example when the mobile phone is close to computer speakers the device itself is called a ferrite bead that is it is made of ferrite a chemical compound made of iron oxide and oxides of other metals this compound absorbs high frequency electromagnetic noise a hole near the rear camera on the iPhone maybe you didn't even notice it but there is a small hole on the back of the iPhone near the flash and the camera lens turns out it has a very important function this is one of three microphones built into an Apple smartphone one of them is hidden at the bottom of the smartphone and as designed for conversations the second is located above the screen and is used during video and voice recording but the third one mounted at the back analyzes background noises and cuts them off during the operation of the two other microphones this is necessary for clear and crisp conversations and to keep high sound quality during video calls ok take a selfie open our cars on Eclipse discs in a plastic bottle cap if you thought that this strange disc under the cap is needed only for promotional purposes then you are wrong turns out it protects the carbonated drink and acts as a gas proof barrier keeping your soda fresh and bubbly sometimes is made of transparent plastic and sometimes even if rubber it helps retain the carbon dioxide in your favorite soda drink punt at the bottom of the bottle have you noticed that some bottles of wine and champagne have a strange indentation at the bottom some even believe that its presence indicates the high quality of the drink but this is not entirely true for the first time a punt that's what the experts call a mysterious dimple on the bottom of a bottle appeared in France when the bottles were made manually by glass blowers back then it wasn't possible to make the bottom flat simply because the technologies were not advanced enough now its parts of wine tradition but don't think that the punx is just an obsolete remnant of the past in fact this part of the bottle has important functions first the Punks prevents the wine sediments in the bottom from mixing with the rest of the contents secondly bottles with pumps are easier to transport and finally when it comes to a sparkling drink the punt helps to evenly distribute the pressure inside the bottle the bottom drawer under the oven a good housewife or househusband can use any free space for storing kitchen utensils and usually they believe that the drawer under the oven is designed as a storage space they're not wrong in thinking that but originally the designers of household appliances intended this drawer for completely different purposes according to their intent the draw was supposed to preserve the heat of the dishes and to heat place before serving food on the table find some time to look at the manual of your oven and you'll find the proof for that ridges on coins people who collect coins from around the world now almost all of them have ribbed edges but have you ever wondered why turns out of this tradition dates back to the 17th century when the value of a coin was estimated by the amount of gold or silver contained in it in other words for example a 5 pound coin contained an amounts of gold worth 5 pounds this has led to widespread fraud though the crooks began to cut the coins around the edges to make more coins later it was very difficult to notice the fraud not everyone carried the scales with them at all times there had to be some way out and then a physicist Isaac Newton came to the rescue he suggested making riched coins in order to eliminate fraud today this technology is no longer needed but it has been preserved in the vast majority of countries as a tribute to tradition metal loops on shopping carts it would seem that there's nothing special about a regular supermarket cart it's only good for keeping it groceries right however there are some interesting details about it take a look at the metal loops next to the handle of the carts few people actually use them but in fact you can hang your bags on them this is especially convenient if you have a lot of fragile stuff or soft stuff in your grocery basket it can therefore be separated from other products balloons and now a bonus see how useful balloons can be a South Korean company suggested using balloons to mark empty spaces in parking lots the cost of the system is minimal the ball is tied to the asphalt and it rises in descends when the car arrives or leaves just imagine how much time gasoline in trouble this simple innovation can save in all corners of the world dude are you looking for new technologies and great gadgets are your thoughts focused on the future do you love huge vehicles and can't imagine your life without robots around here and visit tech zone and you'll find all this and more the link is in the description you interested great [Music] [Music]
