we all love a good secret and luckily it turns out the objects we use every day are absolutely full of them from Coke's biggest secret to how batteries really work join me for yet another dive into some of the most amazing Secrets hidden in everyday things Cola can do if you thought that Coca-Cola's best kept secret was its lucive recipe just wait till you see what else they're hiding right under your [Music] nose turns out there's far more to a Coke can than meets the eye a whole secret inner tube of plastic more in the
clip you just saw the inner truth of an aluminum Coke can was revealed by a remarkable chemical reaction when submerged in a highly corrosive alkaline solution containing sodium hydroxide like drain Unblocker a cocane goes through a chemical process known as hydrolysis this reaction causes the aluminum in the can to dissolve revealing a surprising secret hidden within a plastic lining which resists dissolving but what's it doing there alongside carbonated water and lots of sugar soda contains acid Coke is one of the most acidic drinks in our refrigerators namely because of its contents of phosphoric and citric
acid these acids are corrosive in nature giving Coke a pH reading of about 2.5 that's not much higher than battery acid while we all know sodas like Coke can corrode our pearly whites thanks Mom did you also know that just like the alkaline we saw earlier soda's acidity is strong enough to eat away at metal too and seeing as Coke is sold in aluminum cans that's where our little tube of plastic comes into play made from polymer or epoxy this resin layer is installed in the manufacturing process as a protective barrier between the acidic soda
and the aluminum walls of the can not only does this prevent the liquid from corroding the metal in doing so it also protects the soda's flavor from being tainted by the dissolved metal while you've probably never seen a soda a can in this form manufacturers of canned trinks have been lining the insides of their cans with this plastic coating for more than 50 years but if manufacturers have to go through the trouble of coating every can with this protective layer why not just do away with cans all together in favor of purely using glass or
plastic bottles well not only is aluminum the most abundant metal on Earth but aluminum cans also have a much higher rate of recycling compared to plastic and even glass bottles so the next time you crack One open not only are you in for some refreshing bubbles but also a true Taste of ingenious everyday design brush with the truth after a reminder of just what a can of Coke can do to our pearly whites I'd say it's time for a good old brush while we get up close and personal with our toothbrushes at least twice a
day I hope you might be surprised at how little you know about what you're putting in your mouth you've probably noticed that most toothbrush heads have an array of different colored bristles while you might have assumed these are just an extra touch for Aesthetics these bold bristles are hiding a very deliberate design secret and plain side often blue in color these colored bristles are known as toothbrush indicators and tell us when it's time to change brushes on average most Americans change their toothbrush just twice per year but according to the American Dental Association we should
be switching out brushes at least four times a year for good oral health toothbrushing indicators are designed to fade in color as you brush and once most of the color has disappeared the bristles have worn down Beyond maximum Effectiveness that's when you know it's time to change your brush you filthy animal seral Secrets we're often told breakfast is the most important meal of the day but it turns out there are also some seriously surprising breakfast Secrets served up right in front of us every single morning nearly 3/4 of American households enjoy a bowl of cereal
to start their day but what most of those households don't know is that there's a magnetic secret hiding in every mouthful check this out if you thought many cereal boxes doubling as bowls or coffee pods actually being half empty where breakfast is Best Kept Secrets learning that cereal is actually magnetic probably just blew your mind as much as it did mine many cereals are fortified with a variety of vitamins and minerals as a way to help us meet our daily nutritional requirements one of the most common extras found in your everyday cereal is iron unlike
the iron that occurs naturally in other foods like beef and spinach the iron and cereal is added as a fine powder during production that look a lot like iron filings iron is ferromagnetic which is the strongest type of magnetism in existence so even a small amount can be attracted by a magnet this is how this flake of cereal is moving around the iron inside it is following the magnet but before you swear off cereal forever out of fear of breaking your teeth on chunks of metal things aren't quite as repelling as they may appear even
if a serving of cereal contained a full dose of recommended daily iron which is 8 mg for men and 18 for women both are even less mass than a single grain of rice so there's really no danger attached to chomping down on your morning munchies at least from the iron all the sugar is another story for another time but who knew that eating breakfast could be so metal battery setion I don't know about you but for most of my childhood I assume the batteries we use every day are full of liquid energy that fuels our
devices however most batteries of the kind most household items use are actually dry cell batteries and don't contain liquid instead they're made up of electrochemical cells that convert stored chemical energy into El electrical charges these cells are usually only capable of producing around 1 and 1/2 volts of electricity each but if added together they can achieve a lot more the 12vt a23 battery for example often contains eight 1 and 1/2 volt cells hidden inside the larger battery wrapping and the battery setion doesn't stop there some even bigger batteries like this extra long life 6vt battery
are hiding their inner cells within other batteries another unlikely place you'll find instances of batteries and batteries is in a Tesla car battery which contains around 375 volts provided by hundreds of individual cells well Androids May Dream of Electric Sheep turns out battery manufacturers dream of how many different batteries they can fit inside bigger batteries push for Placebo picture this you walk up to a crosswalk press the button and wait for what seems like an eternity for that little walking man to show himself you cross the Street and for a split second you wonder did
that button actually do anything at all well you're not alone and in reality the world is full of buttons that have been completely lying to you out of the 1,000 crosswalk buttons in New York City for example it's estimated that only about 100 of them actually serve any real function to actively stop traffic the remaining 900 are examples of what's known as a placebo button a button that can be pushed but has no effect whatsoever but what's the point of all this invented in 1964 crosswalk buttons were first introduced in a time when City traffic
was a lot lighter than the gridlocks we see today at that time traffic lights would remain green until a pedestrian pushed the button as the city became more reliant on cars for transport and foot traffic increased the crosswalk button began causing more problems than it was solving and was constantly stopping traffic in its tracks to solve this problem city planners have been gradually disconnecting buttons all over the city and replacing them with time traffic signals and this has since been happening in other cities all over the world as well so why have the buttons there
at all if they don't do anything well there's no official answer to this question some theorize that placebo buttons are placed among us as psychological tricks that give us an illusion of control it's pretty frustrating regardless especially considering less busy Junctions especially those in smaller towns do still function as expected making it pretty hard to tell when you're being duped by a dud button and like those founded crosswalks push to close elevator buttons are also suspected of employing the placebo button tactic turns out that the push to close door buttons in most elevators have been
obsolete for decades though the reason behind it is pretty uplifting when the us Americans with Disabilities Act was passed in 1990 it meant that elevator manufacturers had to remove the function of many push to close door buttons this was to prevent people from getting in and closing the door before a disabled person person has time to get inside however While most of these elevator buttons won't work by default for the public many buildings have keys or codes that can render the buttons operational in an emergency while placebo buttons are designed to be useless I can
think of three buttons that are the complete opposite that you should push right now if you're enjoying my latest batch of everyday Secrets why not head on down and push those likes subscribe and Bell buttons to activate your liftoff into a world of incredible facts and stories that is sure to Tru truly Amaze you all done great now on with the video rated red even with the rise of streaming and at home entertainment nothing quite matches up to a trip to Ye Old movie theater the soda fountains butter drenched popcorn and who can forget the
iconic movie theater seat now you might have noticed that more or less every classic movie theater Ops for red seats this tradition partially stems back to a trend set by 18th century Italian opera houses which were decked out with regall looking red seats to attract wealthy clientele however the color choice in movie theaters today is also a very deliberate design decision that's specially selected to trick your eyes our eyes have two different types of cells that work together to help us detect the presence of light and color the rods are most sensitive to changes in
light shape and movement but are not good for color vision the cones meanwhile are most sensitive to color but they work in Bright Light which is why color is harder to see in the dark different colors have different wavelengths which affect our ability to see them in low light the shorter a color's wavelength the easier it is for our cones to detect them in Darker conditions red light has a longer wavelength than any other color in the Spectrum so it's the first color we lose the ability to identify in the dark even when other colors
are still visible this is known as the pingi effect which is in full effect when the lights go down at the start of a movie as the red seats walls and curtains quickly Fade Into the Darkness our eyes can focus their full attention on the screen and we're not done seeing red just yet there's no doubt the image of a Red Barn in a quaint field is as American as the 4th of July an apple pie but have you ever stopped to wonder why this iconic shade is a farmer's First Choice some believe that farmers
painted barns in a rusty Hue so they would appear to be made of of bricks a more expensive material that made Farmers appear wealthier another popular belief is that farmers paint barns red to help their cows find their way home which seems smart until you find out that cows are colorblind in all colors except yellow and blue now we could talk about all these theories till the cows do or don't come home but the reality is a much clearer picture the early farmers that settled in New England didn't have the extra money for paint but
still needed a way to protect their unpainted barns from from the elements the result was a rusty colored mixture of skimmed milk lime Lin seed oil and red iron oxide from the New England soil which has been found to limit the weathering of wooden surfaces talk about a humble beginning Farmers to this day still paint their barns red and homage to their forefathers Ingenuity though utilizing the entirely modern stroke of Genius that is Home Depot bread tags without a doubt the most iconic lunch menu item of all time the humble sandwich would be nothing without
two slices of good old bread Americans eat more than 300 million sandwiches every single day that's a human to sandwich ratio of around 1 to one that number of sandwiches requires a colossal amount of bread so it's no surprise that a loaf of bread is a staple for almost everyone's grocery list you've likely noticed the colorful tags that seal bread bags but did you realize that these tags hold the secret to the sandwich your dreams while the different colors are mostly there to help employees know when to refresh the bread on the shelves being in
on this color code can also help you shop smarter each color tag corresponds to a different day of the week with each loaf tagged with a color corresponding to the day the bread was baked while there's no universal code for what each color symbolizes generally the schedule most grocery stores use is something like this loaves baked and packaged on Monday or tagged blue Tuesday loaves with green Thursday bread has a red tag Friday with white and Saturday Don's a yellow tag if you're wondering why there are no color tags for Wednesdays and Sundays that's because
these are days that most bread bakeries take a day off from production now you know this tag secret you can use your powers for the good of all sandwiches by picking out the freshest loaf every time you shop happy sandwiching speed Chumps while many drivers consider them quite the nuisance they're there's no denying that speed bumps are an essential part of road safety designed to slow drivers down in areas where there's a lot of pedestrians speed bumps generally slow drivers down to between 2 and 10 mph while driver and pedestrian safety is the priority some
experts believe that speed bumps may not be so safe for our planet according to the UK's National Health Institute because speed bumps cause drivers to frequently accelerate and decelerate which increases car emissions they may be inadvertently contributing to traffic noise and air pollution as a solution city planners in London England have given fake speed bumps a test drive how can a speed bump be fake you may ask well if you take a look at these bumps side on you'll see that they're actually completely flat and are merely an optical illusion from the driver's seat point
of view the faux bumps are painted in such a way that they appear raised like regular speed bumps when in reality they're not experts claim the optical illusion could reduce emissions by up to 20% thanks to the smoother Driving Experience the faux bumps facilitate as the drivers don't have to accelerate as hard afterwards to counteract the decelerating slope of a real speed bump I mean it's a pretty clever way to get people to drive safely in an eco-friendly way but does anyone else feel like it's a little deceptive even the roads can't be trusted these
days let me know what you think in the comments below powerful symbols while we all know we need food and water to power our B bodies there's one other power source that has become just as essential in our daily lives the coveted USB fully powered electronic devices have grown to rule our daily lives and you probably pop your phone and other devices on to charge multiple times a day without a second thought while we all know that this symbol refers to USBS you might not know that this small But Mighty emblem of power has quite
the mysterious history short for Universal serial bus many intriguing theor I have been put forward over the years for what the USB symbol means the most popular theory was that the symbol is a representation of Neptune's Trident known as the dyac while the dyac symbolizes the power of the sea those who propose this theory suggest the USB's three-prong Trident could symbolize the power of technology and adaptability well it's fun to theorize The Mystery of the USB symbol may have a more official solution in 2020 quora user Jim D claimed that he was was the designer
behind the elusive USB symbol and that the real meaning behind it was a far cry from the suggested theories Jim claims that he came up with the symbol while working as a technical illustrator at the digital Equipment Corporation in the 1980s and it was later assigned to the USB which was invented in the 9s as opposed to any Fantastical links to mythology Jim claims that the Trident likee design is actually meant to represent connectivity the larger circle at the base of the symbol represents a computer while the smaller Circle and triangle and square connected to
it represent the multiple different outputs a device like USB could potentially be used for so when the USB technology emerged the generic symbol Jim had been tasked with designing proved perfect for it of course these are merely the claims of one man online so could be fabricated but they certainly seem believable and it's not just the USB there are a massive technological symbols whose true meaning escapes our notice every single day take the power symbol for instance the simple Circle broken by a small line is believed to have been derived from the binary system with
the number one standing for power and zero indicating power off but hey don't hit that power button just yet we've got even more amazing Secrets coming right up Hines and seek one of the most recognizable Brands out there there's no doubt that Hines is the Undisputed king of condiments when you go to a restaurant that's serving hind you know that means they care about quality or does it as an established household brand hindes cost more than many catch-ups used in the catering industry but some restaurants have been using this fact to fool their customers shockingly
20% of restaurants surveyed by Hines admit to refilling Hines katchup bottles with cheaper alternatives to save money and Hines isn't happy in response to this epidemic of counterfeit catchup Hines has devised a solution and it all lies in the label on some of the bottles distributed to restaurants Hines has transformed form their iconic label into a control tool to help consumers check whether the catchup they being served is truly hind the new label includes a red outline that has been perfectly color matched to Hines ketchup on an authentic bottle of Hines ketchup this border is
almost invisible but if there's impostor sauce inside it stands out as a blaring warning that you're the victim of ketchup fraud that'll teach those Saucy Devils Cas is cracked well while it's a no-brainer that a suitcase needs a zipper you might have noticed that most suitcases have not just one but two little pull tabs on their zippers those Nifty little sliders are known in the industry as cars by the way so there's a free hot steaming fact right out of the gates now we're all familiar with the anxiety that comes along with traveling with an
overloaded suitcase and while it might seem like the bulging Cas is working against you it's two zippers are secretly rooting for you to succeed while an overloaded case could pull a single zipper car apart a second zipper pull acts as a fail safe if the first were to fail allowing you to still close your case not only that but having two zipper pulls allows you to reach into just a small corner of your case without having to open the entire thing two Zips also allow you to padlock your suitcase for extra security even without a
built-in lock system yet another lesser known protective design feature on some suitcases are these plastic tabs that help to protect the case from the bumpy Journey that had s behind the scenes at airports offering a little shock absorption in case your case meets with a disgruntled baggage handler because Lord knows careless baggage handlers certainly exist dang It Bobby my prize glassan porcelain doll collection was in there Match Point whether you're a tennis player or not everyone is familiar with the iconic tennis racket but I'll bet you didn't realize just how much thought is put into
its Design This open space just beneath the wet's frame is called the throat and while you've probably seen players use this area to hold spare balls that's not really why it's there also known simply as the triangle the throat is an integral part of a tennis racket's aerodynamic ability the open space allows air to pass directly through the racket creating a lot less drag when swinging it's something absent from vintage tennis equipment and makes the old wooden rackets feel pretty cumbersome by comparison for a second serve of tennis factoids now while everyone knows that the
markings on the court play an integral role in every tennis match you might not realize that the position of the court itself can be even more important while you'd never notice it from the ground if you take a look from the sky you'll find that most tennis courts like these ones at Wimbleton mysteriously face the exact same direction but what's the reason for this aligned orientation seeing his tennis is mostly played Outdoors the position of the sun can play a significant role in the fairness of a game if the sun rises or sets right behind
a player it could really impact their opponent's vision and performance seeing as the sun moves from east to west during the day many tennis courts are specifically built to have a north south orientation to avoid the Sun as much as possible this way the sun will always be located to the side of the court with any glare affecting both players equally unfortunately many clubs are built on plots of land that don't offer enough space for a real choice of orientation so if you ever find yourself losing a match double check which way your courts facing
it might be that you're at an unfair disadvantage or at least you can choose to blame it on that conical cleverness the office water cooler is the best place to get in on all the office gossip but what you may not realize is that there's an even juicier everyday secret right there in your hand while easy to hold the cone-shaped cups commonly found by water coolers are specifically designed to encourage quick drinking as the Cubs can't be placed on flat surfaces this also prevents employees from taking water filled cups back to set down on desks
where it could be knocked over and spilled over computers and other electrical equipment but the true reason behind the cone cup shape May really lie with sustainability and money saving as water cooler cups are designed to be single use cone shaped cups are actually less wasteful as they require less paper to construct compared to the regular shaved cups and hence cost less too plus most importantly of all they make for one hell of a stylish hat shave new world for many guys out there shaving is an essential daily ritual but the next time you lather
up you'll know there's a hidden everyday secret that's been smoothly passing you by check it out while you might be wondering why there's a blank Capri Sun inside your can of Shaving gel I wouldn't recommend trying a swag while shaving foam is packaged in a traditional aerosol can containing both product and gas mixed together shaving gel uses what's known as bag on valve filling en cans with these latter types of fillings the product is filled into an aluminum pouch which is attached to the valve the extra space in the can is filled with compressed air
which squeezes the pouch every time you press the trigger at the top of the can bet you never thought that there could be so many mechanics behind a smooth Chan it's a shave New World indeed balling in secrets with hundreds of domestic leagues Cup competitions and international tournaments taking place each year countless games of professional soccer or football for most of the world are being played every single day if you're one of the three and a half billion footy fans worldwide you've probably lost count of the number of games you've watched but you'll never watch
one the same way again after hearing this thanks to the power of Technology the role of the referee has become more precise than ever before with the introduction of video assistant referee systems back in 2012 but now a new footy invention has booted its way onto the field and it could change the face of soccer as we know it in 2022 the World Cup introduced these rechargeable footballs that are specially designed to help referees make decisions during games the balls are fitted with special electronic sensors suspended inside the sensors are able to send data 50
times per second to the V system to help the the ball's precise position and kick point which helps detect offside disputes more accurately for a fairer game overall is it a little ridiculous that professional soccer players now need to charge their balls before playing maybe but honestly with the way the world's headed it's probably not long before we all have to plug ourselves into the wall to charge overnight so perhaps we should just get used to it what do you make of our latest match of everyday Secrets do you know of any we've missed so
far in the series let me know in the comments below and we'll be sure to use the best ones in our next part thanks for watching
