00:00If you ever find yourself stuck in the trunk of your car, stay calm.
00:04All cars are supposed to be equipped with an emergency latch to help open the trunk from the inside in
00:10the unlikely case it happens.
00:12These latches are so well thought out that they can be opened by people of all ages.
00:17More so, handles are designed to glow in the dark, too.
00:20You can even pull them with a mouth if there's not enough wiggle room to use your hands.
00:25Never mind how you ended up in the trunk in the first place.
00:28Moving on!
00:29If you're ever working with needle and thread, remember you don't need to stick the needle directly into the spool.
00:36You may end up losing the needle altogether, not to mention you can easily hurt your fingers.
00:41A lot of modern sewing kits these days come with a designated place for safeguarding the needles.
00:47It's located at the bottom part of the thread spool.
00:50You'll just need to pull it out.
00:51It's even made to hold multiple sewing needles at a time.
00:56Disposable ballpoint pens come with a little secret of their own.
01:00Did you ever notice that in some of them, there's a small hole in the plastic part?
01:04It's actually a rudimentary ventilation system.
01:07It's supposed to let the ink easily make it to the tip of the pen.
01:12Okay, I know it's in the name, but you really don't need to shake the seasoning shaker to get any
01:17product out.
01:18Don't believe me?
01:19Hey, you're not the only one.
01:21Go grab your favorite seasoning bottle out of your pantry.
01:24If it has one of those removable plastic caps, it's perfect for the experiment.
01:30Instead of shaking the bottle, try holding it from the plastic cap while it's upside down.
01:35Now gently twist the bottle from side to side and, before you know it, you get some gorgeously flowing seasoning
01:42without having to wiggle the shaker and make a mess all over the stove.
01:47On the same note, most salt and pepper shakers should have ridges on the bottom of the glass portion.
01:53In case you get any seasoning stuck in there, place the bottom of the salt shaker against the bottom of
01:59the pepper shaker and wiggle it around so the ridges click with each other.
02:03The seasoning should easily pour out now without you having to open the bottle.
02:08In colder weather, you often have so many clothing layers on you that you can hardly feel the purse or
02:14back straps on your shoulder anymore, not to mention how fast they can slide off.
02:19Some jackets come with a built-in solution for that, in the form of a small tab on the shoulder
02:25with either a hook or a button.
02:27It's meant to be opened and closed comfortably, so you can keep your purse in place at any time.
02:34You're most likely using it merely to peel the skin of potatoes, carrots, or cucumbers.
02:39But you can use your vegetable peeler for chopping fine strips of onion as well.
02:44Just cut the onion into quarters vertically and then start slicing.
02:48This might also help out with those embarrassing onion tears.
02:53Most people miss this one, but should you ever have a closer look at your toothpaste tube,
02:58You will surely see some sort of coloring there, either a dot or a block.
03:03Colors can vary.
03:05They can be black, green, red, or even blue.
03:08These color spots are actually meant to help the assembly machines back at the toothpaste factory.
03:13They recognize when and where these machines need to cut the toothpaste tubes and proceed to fold them for packaging.
03:20For most types of footwear, if there's anything that seems a bit out of place, always know that it's there
03:26for a reason.
03:26Most manufacturers don't put extra items on shoes just for fun.
03:31It would definitely be a waste of time and resources.
03:34For footwear, like boots, for example, there's often a small loop at the top back of the shoe.
03:40It's there to help you when you need to put the shoe on, since you can quickly pull on it.
03:44Plus, you can also hang the shoes somewhere, most likely to dry, since most boots are meant to be worn
03:50in the colder weather.
03:51Now, I've been guilty at least once of overdressing with a bunch of layers, just so I won't need to
03:58jam everything in my check-in bag.
04:00But does it become a problem when you actually have to get seated?
04:04What do you do with your coat or your jacket?
04:07Well, have a closer look next time you board a plane on the seat in front of you.
04:11The hook that keeps the tray table upright can double as a jacket hook.
04:16As long as you don't need to have any meals while in the air, you're good to go.
04:21Now, most mascaras expire within 3-6 months, I'm told, depending on the manufacturer.
04:27But you can help speed up that process if you're not careful enough.
04:31Continuously pumping the mascara wand, trying to mix in the product, actually pushes more air into the tube.
04:37This can make it dry much faster, and you evidently won't get the desired results with it anymore.
04:44There's an easy way to check if your mascara is still good enough to use.
04:48If you don't hear a popping noise when you take the brush out, you may very well need to go
04:53get yourself a new mascara tube.
04:56Now, I know we're living in the era of Bluetooth-connected devices.
05:00But for better quality sound, they still recommend using headphones that connect via audio jacks.
05:07Remember seeing black ridges on those jacks?
05:10They aren't there just to make them fit when you plug them into your phone or laptop.
05:14Made out of a special insulating material, these bands are meant to guard the wires when sound is being transmitted.
05:21Based on the number of bands, you can figure out which end goes where.
05:25Some empty space under noodles in a cup doesn't mean the company producing them wants to cheat you out of
05:31a full portion.
05:32No, no.
05:33It's a manner of keeping the noodles intact during their transportation.
05:37It also helps with the circulation of hot water that is poured over the products before you can enjoy them.
05:43The V-shaped neckline was initially designed to serve a bunch of objectives.
05:48First, as a way of prolonging the life of the garment that would maintain its shape over the years.
05:53It's also there to fit your head through the shirt in case it needs some stretching.
05:57This way, it ensures a snugger grip around the neck.
06:01Lastly, it helps absorb sweat in case you're wearing the shirt while exercising.
06:06Now, it's not necessarily a custom anymore, but you may have stumbled upon a dinner jacket with an additional mysterious
06:14pocket on the right side.
06:15Turns out, this pocket was used by men to easily reach their train tickets, since most of them had to
06:22travel to work every day.
06:23It helped them keep their jacket buttoned up, but also benefited from the use of a pocket.
06:29Now, it's only added as a decoration, and it doesn't serve an actual purpose anymore.
06:34Speaking of things we don't use these days, or at least for their initial purpose, did you know Play-Doh
06:40was originally a cleaning product?
06:43In the 1920s, the market was in need of a product that could help them wipe the wallpapered areas around
06:49coal-burning furnaces.
06:50The recipe for what we now know as Play-Doh was thus invented.
06:55It was manufactured in white only, and was supposed to clean wallpaper by being rolled back and forth over the
07:01dirt.
07:02It was only later, in the 1940s, that new products for cleaning wallpaper were brought up, and Play-Doh was
07:09redirected toward another area of the market.
07:12Now, while I enjoy a nice piece of toast for breakfast, isn't it pesky to have to clean out the
07:18toaster?
07:19Well, not anymore, since I recently found out that toasters have a slide or a panel at the bottom that
07:26helps get rid of all those annoying breadcrumbs easily.
07:32Now, there used to be a time when you could only have access to video games by inserting cartridges in
07:38your console of choice.
07:39These tiny objects gave many doctors a lot of headaches.
07:43People soon started popping up in hospitals after swallowing small game cartridges, especially the younger generation.
07:51Nintendo, the company that manufactures the majority of these devices, had to come up with a creative solution to prevent
07:58these accidents.
07:58So, these days, Nintendo Switch cartridges are purposely coated with specific chemicals that can leave a really bad bitter taste
08:07in the mouth.
08:08Not that I'd, you know, recommend you ever try and taste for yourself.
08:12Hmm.
08:13Think you're ready to see the world in a whole new way?
08:16I hope so, because I'm about to blow your mind.
08:19Have you ever noticed those plastic lines along the side of your phone?
08:23They're the oddly space stripes that seem to have no purpose.
08:27In reality, though, they're probably your phone's most important feature.
08:31Because without them, your device would be little more than a smart paperweight.
08:36They are antenna lines, allowing your phone to remain wireless.
08:41Electromagnetic waves carrying phone, Bluetooth, and Wi-Fi signals cannot pass through metal, which makes up most of the phone's
08:48outer case.
08:49And the glass panel up front also slows those waves down.
08:53It's like there's a bouncer at the door, refusing to let most signals in or out of the phone.
08:58Hey, I've been to that nightclub!
09:00Anyway, that means no phone calls, no texts, and no late-night delivery when you have nothing in the fridge
09:06except one egg and something that might have once been lasagna.
09:09Those little strips of plastic allow the same electromagnetic waves to come and go as they please.
09:15This is why you can call a friend, order a ride, or play an online matching game until 3 in
09:20the morning.
09:21Hey, don't you have to get up early for work?
09:24When you do finally stumble out of bed, make sure you're using this next item correctly to avoid a potentially
09:30upsetting situation.
09:31The zipper, originally patented as the clasp locker in 1851, didn't become widely used until the 1930s.
09:40Now, they're on everything, from bags to jackets to jeans.
09:44And they're not perfect.
09:45They get stuck.
09:47They pinch the skin.
09:48And we all know what happens if the zipper on our pants refuses to stay up.
09:52Well, luckily, this can be avoided.
09:55Most zippers have a locking mechanism built right in.
09:58When the zip is facing down and flat against the teeth, the lock is engaged and the zipper remains closed.
10:04If only I had known that back in school.
10:07What about those metal rivets most jeans have?
10:10They're more than a design choice.
10:12They were added to protect areas that experience the most strain, such as pocket corners and the base of the
10:18fly.
10:19The rivets hold the fabric together, even when it's being stretched and pulled during work.
10:23And since we're talking about clothing, have you ever wondered about that tiny fifth pocket at the front of your
10:29jeans?
10:30Well, first of all, it isn't really a fifth pocket.
10:33Originally, jeans were made with four pockets, including that little one in front.
10:38The fifth pocket is actually the one on the back left, which was only added to jeans in 1901.
10:44The little pocket, though, was important a long time ago.
10:48Cowboys needed to keep their pocket watches safe while riding out on the range.
10:52Yeehaw!
10:53That pocket kept the watches protected, but also handy.
10:57And then, people became so used to it that jeans just look weird without one.
11:01Another strange holdout from a bygone day is that stitched V on the front of some sweatshirts.
11:07What if I told you that those exact stitches hold the whole shirt together?
11:11Well, then I would be lying, and I never do that.
11:15But, back in the 1940s, this V was very useful.
11:19First, the V-stitch was initially used to add a patch of stretchy ribbed fabric to the shirt
11:25so that it could fit over our big heads more easily.
11:28Secondly, these shirts were specifically designed for sports.
11:32So, the V included an additional piece of fabric to absorb the sweat that would build up during a game
11:38or a workout.
11:38As stretchy fabric became readily available and better at handling perspiration, the V lost its traditional value.
11:46But, like the tiny jean pocket, it has continued as a decorative feature.
11:50A reminder of our big-headed ancestors who apparently only sweated just below the chin.
11:56But, moving on.
11:58One place you won't find many people sweating is the golf course.
12:02You will see quite a few fashion disasters, sure.
12:05But sweat?
12:06Not so much.
12:07Golf was invented around the 16th century in Scotland.
12:10Back then, the ball was perfectly round and smooth.
12:14Over time, the ball would become dented from use.
12:17And at some point, golfers discovered that these imperfections actually helped the ball fly farther.
12:23Dimples were added on purpose in the 1900s,
12:26when it was found out that they reduced the aerodynamic drag that slowed down a smoother ball.
12:31And the dimples made the balls easier to control.
12:34And no, not all golf balls are created equal.
12:37The number of dimples can range from 300 to 500, with one company producing a ball with over a thousand
12:44little dents.
12:45Wow, a little overboard, eh?
12:48Need a quick, refreshing drink after a round of golf?
12:51Juice boxes, created back in 1963, are very convenient.
12:55But why do they have these large triangular flaps on top?
12:59Their lifted flaps act as hand grips.
13:02This stops you from accidentally squeezing a full box and spilling juice all over the place,
13:07like onto your favorite t-shirt or the new couch.
13:10Now, when you're done golfing, grab your backpack with that leather diamond patch with two vertical openings.
13:16It's commonly referred to as a lash tab, but I much prefer its other name, pig snout.
13:22I mean, it certainly looks like one.
13:24You typically find these pig snouts on packs used by hikers and climbers.
13:29The diamond is a place to tie any extra gear that they need to carry,
13:33like boots, cooking equipment, or sleeping bags.
13:35But these lash tabs are also becoming more common on smaller backpacks.
13:39They're a nod to the past, but just as useful.
13:42Attach your running shoes to one next time you head to the gym,
13:46keeping those stinky things away from the rest of your clothes.
13:49Now, I'm sure you're a great driver.
13:52But for years, you've probably been neglecting an important safety feature right in front of your eyes.
13:58That rear-view mirror has a small tab located at the bottom center.
14:02It's high time you started using it.
14:04When this is flipped forward, the mirror is in day mode,
14:07providing a strong reflection of everything behind the car.
14:11Flipping the tab backward changes the whole situation to night mode.
14:15This reduces the brightness of the headlights behind you, resulting in a safer drive.
14:21Another cool car tip?
14:22If you're borrowing from a friend, using a rental, or have the memory of a houseplant,
14:27cars feature a handy indicator to let you know which side the gas tank is on.
14:32It's a tiny arrow next to the pump icon that points either left or right.
14:37Where the arrow points, that's where the gas tank can be found.
14:40And that's one less thing you have to remember.
14:43Okay, off to the grocery store.
14:45A regular shopping cart has a useful feature you might have been overlooking.
14:50Carts usually include loops in the metal frame, often behind the child seat.
14:54As you bag your groceries, hang the ones with fragile or squishable items, like eggs or bread, on these loops.
15:01Now, they're out of harm's way when you toss that giant watermelon into the cart.
15:07Later, when you're unloading your groceries, do yourself a favor and grab that box of plastic wrap.
15:13You know, the one that is impossible to unroll without the whole tube coming out while the plastic wrap sticks
15:19to itself.
15:21Check out either end of the box, and you'll see small tabs that you are supposed to push in.
15:26This helps to hold the roll in place so you can easily pull the plastic wrap out without all the
15:32fuss.
15:33Aluminum foil boxes also have these tabs.
15:35Now that you can finally use that plastic wrap, try this appealing hack.
15:41Separate that bunch of bananas and cover each stem in some plastic wrap.
15:45The stem releases a gas called ethylene.
15:48When it reaches the rest of the banana, it encourages the fruit to ripen and turn black.
15:53If you wrap the stems, your bananas will last longer.
15:58And since you're in your kitchen, you might as well warm up that coffee from this morning.
16:03Just remove the gross skin that has formed on top.
16:06Don't eat it!
16:07Of course, as you open the microwave, you'll notice that the glass in the door has a strange black mesh
16:12inside.
16:13This mesh is designed to stop any radiation from passing through the glass.
16:18Like the electromagnetic waves we discussed earlier, radiation can't pass through metal.
16:23That mesh keeps it all safely inside to help you heat up your food.
16:27Thank you, science!
16:29Oh, and about that cup of coffee.
16:31Did you know that the handle size can help you determine how much the mug actually holds?
16:36Let your fingers guide you.
16:38If you can fit two fingers into the handle, then the mug holds 8 ounces or one measuring cup of
16:44liquid.
16:44Three fingers, 10 ounces or one and a quarter cups.
16:48Four fingers, 12 ounces or one and a half cups.
16:51Pretty cool, huh?
16:54You just spent the entire morning running errands up and down the street.
16:58And you finally stop to treat yourself to a cup of coffee.
17:01You enter the nearest coffee shop, place your order, and notice that actually you really need to use the bathroom.
17:08It's a regular-looking public one with multiple stalls.
17:12As you pick yours, the one in the middle, you get inside and your mind starts to wander.
17:17Why on earth do bathroom doors have a half-inch gap between the door and the lock?
17:22And why on earth do they have a huge gap between the door and the floor?
17:26Can we have a drumroll for this moment, please?
17:29Well, my friend, there is not only one specific reason why public bathroom doors have so many gaps in them,
17:36but rather several.
17:37Public toilets are designed to make people spend as little time there as possible.
17:42You aren't supposed to feel comfortable or at home.
17:45So the design would have to reflect this notion.
17:48Here come the gaps.
17:49In some bathrooms, gaps are so big that users may even feel self-conscious about doing their business out of
17:56preoccupation that the rest of the people standing in line will see them.
18:01Then there's the matter of pricing.
18:03Making custom doors can be a heavy burden for the people building public toilets.
18:07This would mean understanding exact measurements so that doors would always fit the mold of the stalls it's supposed to
18:14be installed into.
18:15Now, not all the gaps in public bathrooms are necessarily the same size.
18:20They may vary, even if this variation is small and often unnoticeable.
18:25So these gaps actually help to reduce the margins of errors and to turn production more cost-effective for the
18:32people financing them.
18:33In case a door comes wider or more narrow than it should, the gap regulates the differences and allows for
18:39their installation anyway.
18:41There is also the case of air circulation.
18:44The last thing you want to do in a public bathroom is to trap odors.
18:48So you need a little space under and between the doors to allow the air to flow.
18:54Finally, the gaps are a big safety measure.
18:56It can always allow for people on the outside to see if someone inside a stall isn't feeling too okay
19:02and maybe need some help.
19:04And what about that extra hole in the upper part of the sink?
19:08It has a name in everything, the overflow hole, and it's designed to keep the sink from flooding.
19:14So in case someone forgets and keeps the faucet going for too long, or the sink gets clogged and water
19:20can't drain down from the main drain hole,
19:22the overflow hole comes in to save the day.
19:26Let's say it buys you a little time before you have the entire bathroom floor flooded.
19:30Have you ever noticed how satisfying closing the door of a car can be?
19:34Car manufacturers devote a great deal of time to designing these sounds.
19:39Studies have shown that they create a perceived sense of quality in the buyer.
19:43It all begins with the primary material.
19:46While older cars used to be made with heavier materials, car doors nowadays are produced with lighter tin,
19:52which can make a rather unpleasant metallic sound once you shut them closed.
19:57So car companies employ sound engineers to ensure that there is the exact amount of foam, mats, and tin in
20:04a car's composition to make the most comforting sound possible.
20:08And what about those tiny dots on the top of your car's front window?
20:12The pattern of these little black dots minimizes distractions for your eyes.
20:16This black part, also known as frit, normally gets warmer than the clear parts, which prevents the windshield from deforming.
20:24And no, the tab under your rearview mirror is not made only for the purpose of hanging fluffy dice or
20:30aromatic-pleasing air fresheners.
20:32It's actually a switch that allows you to adjust the position of the mirror, depending on the time of day.
20:38Flip it one way, and it's the daytime driving mode.
20:41Flip the other, and you're ready to drive safely during nighttime as it tones down the glare coming from headlights
20:47of the cars behind you.
20:49Next time you head out to the supermarket, make sure to keep this in mind.
20:53In case you don't have a coin to unlock these shopping carts, there is a well-kept secret that can
20:58help you out.
20:59If you have your house keys on you, check for a rounded key head.
21:03If you happen to find one, try using it to unlock the cart.
21:06It should fit perfectly in there, replacing the need to carry coins around.
21:11Because, if we're being honest, who still has them?
21:15Elevators.
21:15If you want to ride them on your terms, and your terms only, make sure to try something out.
21:20Most elevators have a secret button combination you can use to skip all the other selected floors and go directly
21:27to the one of your choosing.
21:29This might work out, especially on those days when you've pressed 13.
21:32But you wanted to press 33.
21:34On most elevators, this works once you simultaneously press the closed door button together with your floor number.
21:41This should help you get to your floor without stopping.
21:44Some elevators require you to double-press the selected floor numbers, as double-pressing will often cancel the previously made
21:52request.
21:52While other elevators require you to hold the open door button and then double-press the buttons of the floors
21:59you'd like to cancel.
21:59Now, to stay out of trouble, it's best not to cancel the floors of the other people in the elevator.
22:05They won't take it kindly.
22:07Also, keep in mind that there are elevators that might not have this function.
22:11Now, for honey lovers out there, go ahead and raise your hand.
22:15If your pot of golden honey is crystallized, know that it is actually a good sign.
22:21Crystallized honey means that it hasn't been pasteurized, which means better product quality.
22:26With a decrease in temperature, the natural ingredient of honey, also known as glucose, will make it crystallize.
22:33Now, try making the best of it.
22:35To add some texture to your oatmeal or toast, add a layer of crystallized honey and enjoy nature's sugar.
22:41And if you don't like crystallized honey, plop it in the microwave for a minute or two.
22:46Ah, winter and fall.
22:48You know what this means, right?
22:50Sweater weather.
22:51But there's nothing more annoying than wearing your beautiful wool sweater and itching yourself all the way through it.
22:58Actually, I can be more annoying than that, but let's talk about itchy sweaters.
23:02To keep this from happening again, here's the secret.
23:05Turn your sweater inside out and soak it in cold water.
23:08Add two or three tablespoons of vinegar and let it sit for a while.
23:12Then, drain the water.
23:14Now, while the sweater is still wet, massage a generous amount of hair conditioner into the fibers of the wool.
23:21After letting it soak in the hair conditioner for about 30 minutes,
23:24gently press the excess water out of the wool and leave it to dry flat on a towel.
23:30There you go!
23:31No more itchy sweater.
23:33Any fast food restaurant you go to will hand out small paper cups for customers to fill with their ketchup,
23:39mustard, or barbecue sauce.
23:41But if you're eating some chicken nuggets or trying to dip your burger into the cup,
23:45there's always that bit of sauce that seems impossible to reach.
23:49Next time, try unfolding the cup.
23:52It'll turn into a small paper plate, and this way, you'll get all the ketchup you poured in the first
23:57place.
23:59Padlocks used in outdoor environments should be clean and lubricated every three months.
24:04Regular lubrication will help prevent padlocks from freezing in cold weather conditions.
24:09Look for the tiny hole on the bottom of the lock.
24:12Then, pour oil into it, and there you go!
24:15It opens again!
24:17One thing we often neglect is a point in an ointment cap.
24:21These pointy surfaces were designed to help us break the tinfoil protection of the ointment tube.
24:27You just turn the cap over and break the ointment seal with its own cap, and there you go!
24:33After a long day of work, all you really need to do is a bubble bath.
24:37You turn on the hot water and let it run for a few minutes.
24:40You might even light a candle and pour some essential oils into the water.
24:44Then, in comes the liquid soap.
24:47You stir the water until the entire surface of the tub water is crammed with bubbles and make your way
24:53in.
24:54The bubbles in a bubble bath have a fundamental primary function.
24:57Their job is to preserve the water's temperature, just so you can have warm water for longer.
25:03Do you have sweaty feet?
25:05Weird question, I know.
25:06But if you're one of these people, here's some good news.
25:10All is not lost.
25:11Try putting a dry teabag inside your shoes and storing it in a dry place for a while.
25:17The teabags will absorb the humidity and the smell off the soles of your shoes.
25:22So, here I am thinking, shouldn't we have learned these things in school?
25:26Well, either way, if you learned something new today, make sure to tell us about it in the comments below.
25:39Okay, I know it's kind of cold to the touch, especially on a freezing winter's day.
25:43But did you know that brass doorknobs actually serve a purpose apart from looking classy and shiny?
25:48Since it's a copper alloy, brass has antimicrobial properties.
25:52That means it can help get rid of harmful germs and bacteria, sometimes in up to two hours.
25:58In high-traffic areas, that's all the more useful.
26:01But since brass is much costier than other metals like nickel and steel, you barely see these types of doorknobs
26:07anymore nowadays.
26:08Speaking of lovely multi-purpose items, most screwdrivers have a tiny little secret of their own.
26:13They can sometimes be slid through a wrench so that they can be used to create more torque when twisting.
26:19Not to mention the uses when it comes to bolts in hard-to-reach places.
26:24There's a reason why buttons on women's shirts are for the left-handed, and it has nothing to do with
26:29fashion.
26:30This practice dates back to the times when chambermaids were helping ladies dress themselves,
26:34and it was easier for them to perform their job with this orientation.
26:39Having the buttons placed as such indicated a sign of wealth,
26:43so it's easy to imagine why the practice carried on, even though most people dress themselves nowadays.
26:49Next time you receive a package in your mail, take a look at your box cutter.
26:53If it features some diagonal lines on the blade, you're in for a little design perk.
26:58Turns out that these are blades that snap off.
27:01Continuously cutting cardboard can dull the sharp edge of the blade.
27:04To help prevent the need to buy a brand new box cutter,
27:07the top segment along the next line can be broken off to reach a new sharp edge.
27:11To do this, check out the small hole at the base of the tool, sometimes called the blade snapper.
27:18The people that first came up with this brilliant invention were engineers,
27:22inspired by the way chocolate bars are segmented.
27:25Hold on a minute, don't throw away the cardboard package just yet.
27:28Most likely, you'll have some silica gel packets somewhere at the bottom of the box.
27:32Since this gel is basically a drawing tool, it gathers up the moisture out of its environment,
27:37so you can store these packets for further occasions.
27:40Whether you'll need to dry out your phone or some other electrical object,
27:44you can place them in a container next to the silica gel to reduce the damage.
27:49You don't have to be a mechanic to know when a standard car tire needs replacing,
27:53since they come equipped with a neat indicator.
27:56Take a closer look, and you'll see that treads within the tire are a bunch of rubber notches.
28:01When the treads are evened out with the perpendicular bars,
28:04it's a sign you need to book an appointment with your local car service.
28:08Since most likely, the tires have lost most of their traction and may not be safe for driving any longer.
28:14The upper corners of a car windshield feature textured black dots melted into the glass edges.
28:20This neat add-on isn't there for design purposes.
28:23It's called Frit Glazing, which means that a special type of ceramic paint is added to the window for protecting
28:31its sealant from UV rays.
28:32It also conceals and creates a coarser surface for the adhesive used to set the window in place.
28:40Whenever you're up for a drive, check out if there's a small tab under your car's rearview mirror.
28:46Bet you didn't know it's there to help switch the mirror from daytime to nighttime views.
28:51It uses a prismatic glass technology to blur the reflection and reduce the glare of headlights behind you in traffic.
28:59People came up with these manually tilted mirrors in the 1930s, but they became standard somewhere in the 1970s.
29:06While you're in the car, check out the headrests, as you most likely don't know that they carry a little
29:12disguised purpose.
29:13Of course, they're adjustable to accommodate passengers of any height so that they get the proper support for their heads
29:19and necks.
29:20The hidden feature is that they are detachable and come with two very solid metal bars.
29:26Should you ever find yourself stuck in a car and need to make a fast getaway?
29:30These bars come in handy to crack out the car windows.
29:34So you're out for a drive and you're suddenly out of gas.
29:37What I'm about to describe sounds more like a meme than an actual situation bound to happen.
29:41But what if you're in such a hurry that you accidentally drive off with the gas nozzle still in the
29:47tank?
29:48Well, the nozzles have been designed to prevent any hazards from happening, rest assured.
29:53They feature a breakaway device that will allow the hose to separate when taken out with enough force.
29:59Initially designed in the early 20th century to be worn exclusively by basketball players,
30:05sneakers soon became one of those fashion fundamentals, similar to jeans and leather jackets.
30:10If you take a closer look at them, you'll see they have two extra holes on the side, similar to
30:15the shoelace holes.
30:16They're manufactured as such, not only to provide extra ventilation,
30:20but to allow people to get extra creative with their laces when wearing the shoes.
30:25Admit it, you've always thought that chopsticks are merged at the end for the sole purpose of keeping them together
30:30until you're ready to dig into your meal.
30:32That may or may not be the whole truth.
30:35Under a more detailed inspection, the wooden tools feature a square-shaped end.
30:40Chopsticks manufactured like this date back to an old Japanese traditional design,
30:45which can help with breaking the ends easily.
30:48The separated end can then be used as a resting block for the chopsticks
30:52to keep it more sanitized in hopes it can be used again,
30:55since they won't be touching the table or any other surface.
30:59Women's bikes have a special design, which, surprisingly, has a historical and fashionable purpose.
31:05The lower frame is for the most part meant to make up for the generally shorter height of ladies,
31:10compared to that of the average gentleman.
31:12While that is the case for handlebars and saddles,
31:15the overall frame is lower for an additional purpose.
31:19Way back when women wore long skirts and dresses all day,
31:22every day they needed to make sure their outfits wouldn't get caught in the frame.
31:26That's how we came up with a lower-framed bicycle,
31:29perfectly made for women and their needs at the time.
31:33The fact that toothpastes are multicolored is not just a nice perk to make dental hygiene more fun.
31:39There's a secret meaning related to each of the colors, which dates back to the 1970s.
31:44In those days, people grew more and more interested in their oral health care,
31:49and as such, they were looking for products which could do more than merely clean their teeth.
31:55One company was the pioneer in that regard, adding mouthwash to its toothpaste, meaning the blue strip.
32:01They later added on the red strip, meant to feature ingredients which helped with gum care.
32:07Speaking of toothpaste, check the cap next time you open a new tube.
32:10You may be in for a little surprise.
32:13There's a pointed cone shape inside the cap,
32:15so you can puncture the seal of the toothpaste without cutting yourself or ruining your manicure.
32:20Not to mention, it's more hygienic since you won't be able to transfer germs or other bacteria into the product
32:26itself.
32:28On the subject of bathroom countertop items,
32:31toothbrushes come with a neat add-on hidden in the bristle patterns.
32:34Apart from making the toothbrush look cooler, they also do come with a practical purpose.
32:40Most toothbrushes come with a pattern of blue bristles intertwined with white ones.
32:44The blue dye is meant to fade out, signaling the time when you need to replace your toothbrush.
32:50Dentists say that toothbrushes should be replaced every three to four months,
32:54but it does serve as a great reminder in case you forget.
32:58Still love playing with Lego?
32:59Don't judge.
33:01Hey, it's a great hobby for all ages.
33:03Notice there's a hole on top of the Lego heads?
33:05Behold, you're looking at a safety feature that the people at Lego designed to prevent choking hazards.
33:11The most dangerous issue should a person swallow any of these pieces is the blocking of the airways.
33:18Designing a hole inside the Lego head helps the air to flow freely through the piece until it can be
33:23removed safely.
33:25We're now used to all sorts of modern light bulbs,
33:28some tubular, some shaped like diamonds, and some even twisted all together.
33:33Historically, light bulbs were round and the initial shape served a purpose in itself.
33:39It was mainly connected to the fact that glass bulbs were hand-blown,
33:42which gave them the round shape to begin with.
33:45The hidden practical reason was that the light bulb filament needed to be at the same distance from every surface
33:50of the glass sphere.
33:52The easiest way to achieve this was to make the glass in the shape of a globe.
