00:00So, consider this. People started making ridge patterns on coins in past centuries to fight counterfeiters.
00:07In the old days, cheaters cut off the smooth edges of coins and used that metal to mint new money.
00:13But with ridges, it became impossible to hide the cutting.
00:17These small cylinders on the charging cables are called chokes or ferrite cores.
00:22They're magnetic iron oxide that helps to prevent electromagnetic interference.
00:27In simple words, they protect your device from faults.
00:31We all know about these little pockets on jeans where people used to keep their pocket watches.
00:36But what about these small metal buttons? They help hold the fabric together.
00:41Weavers put the buttons where the jeans can tear during moving and straining.
00:45These small holes on some backpacks were designed to tie extra gear to them.
00:50So, you can pass ropes through them and tie sneakers if you don't want to keep them inside your backpack
00:55or in your hands.
00:57This tiny dot next to the camera on your iPhone is a microphone.
01:02It helps to get good quality of sound while taking a video.
01:06The Spotlight feature on your Mac can be used not only for a quick search of files and apps.
01:12It also works as a calculator.
01:14Just type in a mathematical problem you need to solve.
01:17Spotlight also uses internal dictionary data.
01:21Enter any word in the search bar and you can get information about it.
01:25You've just bought a new bottle of oil.
01:27You're taking off the lid and looking at this little cork that you can tear off by pulling the loop.
01:33Take this thing out, but don't throw it in the trash.
01:36Put it back in an upside-down position to control the pour's flow by pressing your finger against it.
01:43Tiny ridges on the F and J keys on the keyboard help your fingers navigate during touch typing.
01:50When your index fingers are on these ridges, you know exactly where other letters are.
01:55The brushes on the sides of the escalators are not for polishing your shoes, but for your safety.
02:01These nylon bristles prevent your laces and clothes from getting inside the escalator's gears.
02:07No, that wouldn't be good.
02:09Most door handles are made of brass.
02:12This type of metal is good for fighting microbes.
02:15Bacteria can't multiply that much on such surfaces.
02:19These public toilet's cubicles don't look private for a reason.
02:23Huge gaps at the bottom were created to make you want to get out of there as soon as possible.
02:28Thanks to this design, there are almost no cubes.
02:32You can use a plastic lid from soda cups as a coaster.
02:35It has the perfect shape to hold your drink and keep a table surface from getting wet.
02:41Don't turn the lid upside down.
02:43Just put it on the table the same way it was on the cup.
02:46If you're stuck in a car during an accident and can't open the doors,
02:50you can use bars from the detachable headrest to break the window and get out.
02:56Remember those small plastic discs under the bottle lids?
02:59This little thing helps preserve vacuum inside bottles, keeping soda in a fizzy state.
03:06You've probably watched food heating in a microwave at least once in your life.
03:10Exciting, I know!
03:12But why do the developers make the doors so dark?
03:15This black film is necessary to block electromagnetic fields.
03:19Tiny dots on padlocks next to the keyhole are designed to dry out the moisture if water gets inside the
03:26lock.
03:27Also, if the lock gets jammed or starts to rust, you can pour oil into it through this hole to
03:33fix the problem.
03:35A golf ball is covered with tiny craters for good aerodynamics.
03:39They're called dimples, and this design helps the ball fly further and more evenly.
03:45Some mugs have a little groove at the outside of the bottom.
03:49It helps water flow out and prevents it from accumulating when the cup is in the dishwasher.
03:55Sunglasses were first used not to protect your eyes from the sun.
03:59They used such glasses during Arctic expeditions.
04:02A huge amount of snow can blind you just like a bright flash.
04:06To save their eyes, they came up with these unique glasses.
04:10You can use any t-shirt not only for dressing, but also as a protective layer for your luggage.
04:16Just put your clothes on your suitcase as a cover, and don't waste time plastic wrapping it.
04:22A button on the back of the shirt collar is there to keep your tie under the collar.
04:26Yes, people don't use it as intended because all ties are thinner now.
04:31But this button is still there as a decorative function.
04:35And here's the initial purpose of a tie.
04:37They created it in the 17th century Europe that tightened the collar.
04:42This way, people protected their necks from a strong wind.
04:45Then, they got used to this part of the outfit and made it a must-have accessory for royal gatherings.
04:52Soft pom-poms on hats were first invented several centuries ago.
04:57Sailors use them to avoid hitting their heads against low ship ceilings and ledges.
05:01They make most clothes hangers from cedar wood, since it contains many natural oils repelling moths that love to eat
05:09your clothes.
05:11A light bulb is spherical because such a shape allows the light to distribute evenly.
05:16Also, such light bulbs are cheaper and easier to produce.
05:20Ever found these pieces of fabric and new clothes?
05:23They're not just patches, but also testing subjects to use before washing.
05:28You can put this piece in the washing machine and see what happens to it.
05:32If everything is fine, then you can safely put your clothes in.
05:36Your ceiling fan has two modes of work, winter and summer.
05:41You need to find the switch on it.
05:43Push it up to activate the winter mode and down for the summer one.
05:47In summer mode, the fan pushes the air down.
05:50It pulls the air up in winter.
05:53Most people have this ground plunger in the bathroom.
05:57In movies, they use those to eliminate a blockage in the toilet.
06:01In fact, the plunger is to get rid of a blockage in the sink.
06:04For the toilet, you need another special device.
06:08The extra space under your oven is not for keeping pans and pots.
06:13You can put some dishes there.
06:15The heat of the stove will keep your meals warm.
06:17It's useful if you're waiting for friends late for dinner.
06:22You're taking a pack of popcorn out of a microwave after heating.
06:26See the little hole at the top of the popcorn bag?
06:29You can use it to get rid of small unpopped grains.
06:32Shake the pack over the plate, and all the grains will fall out through the hole.
06:38Almost all people use a travel pillow incorrectly.
06:41Usually, they put two ends forward and lay their heads back.
06:45Try to turn the pillow on the other side.
06:48The arc should be under your chin, and the two ends should be directed back.
06:52Lay your head forward, and your neck will feel way more comfortable in this position.
06:57And you'll get a good nap.
06:59They create magnets in a horseshoe shape to increase their magnetic power.
07:04The blue part indicates the south pole, the red part, the north one.
07:09The two poles work simultaneously and increase the attraction.
07:13Thanks to the perfect aviation design, most planes can fly a long distance even without an engine.
07:20In 1268, Roger Bacon made the first written mention on using telescope lenses for optical purposes.
07:28Magnifying lenses inserted in frames were popular for reading, both in Europe and China at this time.
07:34So it's still a question if the West took it from the East or vice versa.
07:39If you find yourself in the middle of the sea without food, sorry, you can try fishing.
07:46You can use anything for bait.
07:47Your phone, watch, keys, and you can use laces as a fishing line.
07:52Tie the bait and throw it into the water.
07:54And good luck catching the fish that swallowed your phone.
07:58It's going to be a whopper.
08:00You can turn over the tab on a lid of soda cans and use it to hold a cocktail straw
08:05in place.
08:06The blue half of the eraser wasn't originally created to delete the ink.
08:11Initially, the blue part erased inscriptions and drawings on thick paper.
08:15The red part couldn't do it without leaving streets, but the blue one handled this task perfectly.
08:22Most of us tear sticking notes off incorrectly.
08:25Try not to do it from below, but from the side along the licking log.
08:30The paper will stick to the wall for longer this way.
08:34Ever wondered what these two holes in the lollipop stick are for?
08:37All the time, you say?
08:39Well, when they put the bar in hot syrup, the liquid flows inside.
08:44It creates a solid attachment for the plastic.
08:48And so it goes.
08:52It's your birthday party!
08:54You made a wish and blew out the candles.
08:56It's time to cut this delicious round cake.
08:59Your guests can't wait to taste it.
09:02Wait a minute.
09:03Are you sure you actually know how to cut it?
09:06Normally, people prefer making V-shaped slices by default.
09:11Although this method is very popular, it's far from perfect.
09:15Some guests won't get enough frosting, while others will get too much.
09:19And besides, cakes are pretty fragile, so crumbs can fall all over the place.
09:24This alternative method went viral because of its incredible practicality.
09:29All you need to do is press a large cutting board against the cake very gently.
09:35Then slice the cake across horizontally and move the long piece onto the cutting board.
09:41Now, you can cut one big slice into several smaller slices for the guests.
09:46This will give them a chance to order exactly as much or as little dessert as they really want.
09:52Wait, who wants just a little dessert?
09:55You will also prevent the leftover cake from drying out too soon.
09:59And if someone asks for more, just keep repeating the cutting board trick as many times as you need to.
10:06If the number of guests at your party doesn't match the small size of your cake, there's an easy tip
10:11to make sure everyone's served.
10:13Cut the cake into small cubes.
10:15Put them into paper baking cups.
10:17And pierce the slices with a toothpick to make sure the layers don't fall apart.
10:22You can serve this cake canapé on a tray.
10:26When you don't have a knife at hand to cut a cake, dental floss will help you out.
10:31If you manage to do the work gently, the floss will glide through your cake with ease and keep the
10:37icing decoration in perfect order.
10:39This method is also very handy when you want to cut pie or cake layers horizontally.
10:45Of course, it's better to use dental floss with a neutral flavor if you don't want to feel the minty
10:50frost in your dessert.
10:53You're hanging some pictures or framed diplomas on a wall.
10:56I have several.
10:57But they refuse to hang straight.
10:59If you're using a wire and only one nail, it's very likely that the picture will get crooked.
11:05So, the better solution is to use two nails.
11:08They will help the artwork stay there straight.
11:11Also, make sure that the wire is only as long as it needs to be.
11:15Otherwise, the excess slack will make the picture stagger on the wall.
11:19And finally, you can use these small, clear sticky tabs.
11:23Stick them on the bottom corner of either side of your framed pictures and prevent them from slipping.
11:30Now, even the highest quality markers stop working sooner or later.
11:34But that's not a reason to say goodbye to them.
11:37Glue the markers around the outer edge of a regular flower pot.
11:41Then spray this construction with gold paint.
11:44You'll get a glamorous vase that will spice up your interior.
11:47To complete this project, you can use not only a pot, but any other cylindrical vase or tin cans that
11:55match the size of your markers.
11:57Have you ever spilled your hot drink down on your clothes as you were walking from the cafeteria to your
12:03desk?
12:03Probably yes.
12:04Most people wrap their hands around the mug or use a handle.
12:08But none of these methods is perfect because they leave room for burns.
12:13Recent studies have revealed the best way to hold a coffee mug to prevent any spillage.
12:18And I bet you don't use it on a daily basis.
12:21Put your hands in a claw-like shape and grip your mug from above with your fingers.
12:27This will protect you from burning your palm and keeping your outfit tidy.
12:31And besides, it looks kind of elegant.
12:34Now, in case you didn't know, there are little tabs on the sides of your foil container.
12:40You're supposed to push those in.
12:42Now, when you pull the foil out, it's going to glide effortlessly.
12:46And the foil tube will be fixed in the container.
12:50Shoe stores usually sell their items with small plastic hangers.
12:54Don't rush to throw away this accessory.
12:57It's not so worthless.
12:58If your shoes ever get wet, you can use it to hang them on a radiator so they dry quickly
13:04and evenly.
13:06This trick is especially handy when you get your feet wet on the way to work.
13:11If you like to wash and dry your shoes in a washing machine to keep them fresh and tidy,
13:16you know that it can get really noisy.
13:18To avoid the sound of rocks rolling around the drum, put your shoes and your laces inside a mesh laundry
13:25bag.
13:26If you don't have a laundry bag, try using an empty pillowcase.
13:30You can also put a large old towel in the washing machine together with your shoes.
13:35It'll rub against the shoes and provide additional cleaning.
13:39Just make sure you don't wipe your face with this towel afterward.
13:43Glass cleaning spray is a great emergency tool to restore your patent leather shoes.
13:49Just spray it on your shoes and wipe them using a soft dry cloth.
13:53Voila!
13:54Shining bright like a diamond.
13:57Got some creases on your shoes?
13:59No panic.
14:00Stuff your shoes tightly with some fabric to bring them back to their original shape.
14:05Then put a damp towel over the crease.
14:07Gently steam the crease with an iron.
14:10It'll get softer or disappear completely.
14:14Here's a genius tip for storing and serving fresh herbs.
14:18Cut and mix different herbs.
14:20Then put them in a plastic bottle.
14:22Screw the cap and keep it in your fridge.
14:25Now you don't have to chop your herbs every time you're cooking something.
14:29You can also make an exclusive salad dressing.
14:32Just add some oil, spices, and sauce into this bottle and shake it to mix all the ingredients.
14:39When you're reheating your food in a microwave, some part of the meal gets too hot while the rest of
14:45it stays frosty.
14:47So, in case you've been looking for different tips to deal with this issue, here's the classic one.
14:52Put your food on a plate and make a hole in the center so that your meal is donut-shaped.
14:58This way, the microwave will heat it more evenly.
15:01But don't put the dish in the center of the turntable.
15:04To heat it evenly, it's best to keep it on the outer edge.
15:08If you need to heat up two meals at the same time, put a clean upside-down cup inside the
15:14microwave.
15:15Then put your second plate on top of that cup.
15:18There you go! It's easy and time-saving.
15:22You can squeeze lemon juice out using ordinary kitchen tongs.
15:27Cut the lemon in half and put one half into the tongs.
15:30Now, press them under a bowl to collect the juice.
15:33Add some water, sugar, and ice, and enjoy your lemonade!
15:39You're cooking popcorn in a microwave and can't wait to start watching the new episode of your favorite show.
15:45After one or two minutes of microwaving, little hard kernels still stay on the bottom of the popcorn bag.
15:51People tend to grab them by mistake.
15:54Biting these little betrayers can be fatal for your teeth.
15:57But luckily, there's a little slit in the bottom of the bag.
16:01Here's what you're supposed to do.
16:02When your popcorn is ready, don't rush to open the bag.
16:06Turn the bag upside down and shake it vigorously under a bowl.
16:11All the unpopped kernels will come out.
16:13Now you can enjoy your snack safely.
16:17If you have accidentally burnt the food on your stove and want to avoid dealing with fire detectors, here's a
16:24simple trick.
16:25One of the best ways to remove smoke quickly is to use a half-wet towel.
16:30Hold on to the dry side of the towel and keep flinging it around over your head.
16:34The damp part of the towel will absorb the solid particles in the smoke very quickly.
16:40And there's no need to use a knife to peel kiwi.
16:43Just cut off the top and the bottom of the kiwi.
16:46Then gently insert a tablespoon inside of the kiwi and twist it to separate the skin from the fruit.
16:53Wow! Your kiwi is now peeled!
16:56However, some people prefer eating kiwi with skin.
17:00It's perfectly edible and provides lots of fiber, folate, and antioxidants.
17:05So, if you don't mind this fluffy texture, go ahead.
17:09But don't forget to wash it first.
17:13You know, there are all sorts of amazing things you can do with products already lying around the house that
17:20were meant for other things.
17:22We'll explore some of those, plus everyday items that have other purposes you may not be aware of.
17:28I'm also in a silly mood, so hey, let's have some fun!
17:33Many pairs of kitchen scissors today have a serrated opening where the handles and blades meet.
17:38You can use this as an herb stripper to de-stem difficult herbs like thyme, rosemary, and chives.
17:45Saves you a lot of time trying to pick the leaves off by hand.
17:49And if you're short of a vase, you could present roses to your significant other this way.
17:54Just be careful when you're pointing the sharp end.
17:58The metal tab on soda cans can be flipped around.
18:02You can slip a straw in place so you don't have to hold it up to your mouth.
18:06This stay-on tab replaced the pull ring tab created in the early 60s.
18:11You remember those, don't you?
18:12Those could be quite sharp and easily discarded where they could be a menace for others.
18:18Now, you can pop your straw straight into one.
18:21Also means you can produce some bubbles and make a mess.
18:26Sometimes, when you purchase an article of clothing, you receive a plastic baggie with an extra button and a swash
18:32of fabric.
18:33While the fabric is clearly used to patch holes, it can also be used to test the effects of various
18:40cleaners on certain surfaces.
18:41It's handy, too, to test wash cycles before using them to wash the whole garment.
18:47And if you want to clean your nose with it, that suggestion never came from me.
18:53You can use a screwdriver for leverage if you're having trouble lifting or moving something.
18:58Some also have a hexagonal-shaped handle that fits inside a wrench or spanner.
19:04You can use it to improve torque and, again, for leverage.
19:07A little easier on your hands.
19:09Some of us aren't that strong.
19:11Or maybe that's just me.
19:14Rubber bands are great for many things.
19:16But if you have a bottle that's hard to open, you can wrap the band around it for a better
19:21grip.
19:23Escalators have those fluffy black brushes for a similar reason that some have yellow lines on their steps.
19:30To try and deter people from getting too close to dangerous places.
19:34People don't always take notice.
19:36And sometimes, clothing can drape close to a point where the step meets the edge or skirt.
19:41The brush is a little barrier to help prevent this from happening.
19:45They can also catch bits of fluff and prevent other small things from falling down into the gaps.
19:52Your average pair of jeans has several features that are both functional and somewhat sentimental.
19:59The metal rivets around the pockets help secure the stress points.
20:02This ensures they last a bit longer than average, though not all jeans have them.
20:08Many still have a tiny pocket, directly above the main pocket.
20:13This was originally meant to hold a pocket watch.
20:16Even though pocket watches are mostly a thing of the past, many people still use this space to store coins,
20:23rings, or even a portable USB.
20:27This may seem a little obvious, but if you've ever wondered what all the notches are in a car tire,
20:33it's for traction on the road.
20:35However, there are also a good indicator if your tire is getting too worn down.
20:40If those notches aren't so deep anymore and are almost flush with the road, it's time to replace them.
20:47If you don't, the next time you try to stop suddenly at a stop sign, you might be surprised to
20:53find your car has turned into a giant roller skate.
20:57Those takeaway containers most associated with Chinese restaurants are designed to not only carry your food home, but to store
21:05them in the fridge.
21:07They double as a plate, as you can eat straight out of them and don't have to worry about dirty
21:12dishes.
21:13Yay!
21:13They were actually patented way back in 1894 to transport freshly shucked oysters and were known as oyster pails.
21:22They were later adapted to use as leak-proof containers for food.
21:27While you're sitting on an airplane and looking out the window, you may have noticed those little holes, or in
21:34some instances, a small singular opening near the bottom.
21:37This is called a breather hole, and no, it's not for you.
21:41It's designed to equalize the difference in air pressure which builds up between the pressurized cabin and the atmosphere outside,
21:49especially during high altitudes.
21:51It also releases moisture from between the panes to avoid frost from forming on the windows and obstructing that all
21:59-important view.
22:00Sorry, but it looks like you won't be drawing a smiley face on it anytime soon.
22:06This was first introduced way back in 1956 by a company in Japan.
22:11Pretty cool, huh?
22:12They got their inspiration from snap-off rows on chocolate bars.
22:16Just don't get the two mixed up.
22:19One doesn't taste good.
22:21When it comes to measuring tape, almost every reel has an empty slot in the metallic end.
22:27This is called a nail grab, so you can attach it to a nail or screw.
22:32A handy trick to do measurements without requiring someone else to hold it in place.
22:37Ooh, very nifty.
22:40Bobby pins have grooves on one side to hold your hair in place better.
22:45Crazy notion, huh?
22:46The straight side goes face up while the grooves go down against your head.
22:51They're called bobby pins because of the bobbed hairstyle, which was popular in the 1920s, though the pins were invented
22:59in the 19th century.
23:00The look is gone, but the pins remain.
23:03Please take them out before you wash your hair, as they don't look great stuck to your fingers.
23:09If you've been in a car or a bus and noticed the textured black dots baked into the black edges,
23:16you've probably worked out that it's not there for its pretty looks.
23:19It's called FRIT, a ceramic paint.
23:23Its main purpose is to protect the window from ultraviolet rays.
23:27It also creates a rough surface for the adhesive to cling to.
23:31Now, if you see a pink lump of adhesive in the corner, please do not touch it.
23:37It's actually someone's old bubble gum.
23:41If you take a look at the bottom of the lock, chances are you'll see one or two little holes.
23:46This is to let water out from the inside that may have been trapped due to rain.
23:51This mini-draining capability prevents the inner working from rusting over or freezing in place if the weather is very
23:59cold.
24:00If, in another situation, the lock becomes stuck, you can ease an oil-based product inside to lubricate the lock
24:08and get it working again.
24:11If you've lost the key and want to ease your frustrations, you can yell into the holes.
24:16It won't do anything to unlock it, but it may help you feel a little better.
24:21Some dress shirts have a fabric loop on the back.
24:25You guessed it, it's used for hanging the shirt up.
24:28The loops were reportedly first used in the navy, as it was easy to simply hang them on the wall.
24:34During the 1960s in colleges, the fashion of the day was to wear the shirt buttoned all the way to
24:41the top, which made them difficult to hang.
24:43So, designers began putting the loop on the back.
24:47If the student removed the loop, it signified that they were going steady in a relationship.
24:52Unless your friend ripped one off for a prank, now everyone's asking whom you're with.
24:58There's a little more to this story, but we haven't got time to hang around.
25:03And yes, that's a bad pun.
25:05On purpose.
25:06It's what I do.
25:08Ever wondered why coins have those little ridges along the edge?
25:12It's a leftover from earlier times when they were worth more.
25:17Counterfeiters could easily file the edges off to sell as gold or silver coins to make some profit.
25:23The ridges were created so it was much easier to tell which of the coins had been altered.
25:28It's not needed today, but the coins still have that altered style.
25:32Now, if you ever get really bored, you could try counting how many ridges there are.
25:38Actually, that is a very boring idea.
25:41Forget that and watch another Bright Side video instead.
25:46Okay, I know it's kind of cold to the touch, especially on a freezing winter's day.
25:50But did you know that brass doorknobs actually serve a purpose apart from looking classy and shiny?
25:55Since it's a copper alloy, brass has antimicrobial properties.
25:59That means it can help get rid of harmful germs and bacteria, sometimes in up to two hours.
26:05In high-traffic areas, that's all the more useful.
26:08But since brass is much costlier than other metals like nickel and steel, you barely see these types of doorknobs
26:14anymore nowadays.
26:16Speaking of lovely multi-purpose items, most screwdrivers have a tiny little secret of their own.
26:21They can sometimes be slid through a wrench so that they can be used to create more torque when twisting.
26:26Not to mention the uses when it comes to bolts in hard-to-reach places.
26:31There's a reason why buttons on women's shirts are for the left-handed, and it has nothing to do with
26:36fashion.
26:37This practice dates back to the times when chambermaids were helping ladies dress themselves,
26:42and it was easier for them to perform their job with this orientation.
26:46Having the buttons placed as such indicated a sign of wealth,
26:50so it's easy to imagine why the practice carried on, even though most people dress themselves nowadays.
26:56Next time you receive a package in your mail, take a look at your box cutter.
27:01If it features some diagonal lines on the blade, you're in for a little design perk.
27:05Turns out that these are blades that snap off.
27:09Continuously cutting cardboard can dull the sharp edge of the blade.
27:12To help prevent the need to buy a brand new box cutter,
27:14the top segment along the next line can be broken off to reach a new sharp edge.
27:19To do this, check out the small hole at the base of the tool, sometimes called the blade snapper.
27:25The people that first came up with this brilliant invention were engineers,
27:29inspired by the way chocolate bars are segmented.
27:32Hold on a minute, don't throw away the cardboard package just yet.
27:36Most likely, you'll have some silica gel packets somewhere at the bottom of the box.
27:40Since this gel is basically a drying tool, it gathers up the moisture out of its environment,
27:44so you can store these packets for further occasions.
27:47Whether you'll need to dry out your phone or some other electrical object,
27:52you can place them in a container next to the silica gel to reduce the damage.
27:56You don't have to be a mechanic to know when a standard car tire needs replacing,
28:00since they come equipped with a neat indicator.
28:03Take a closer look, and you'll see that treads within the tire are a bunch of rubber notches.
28:09When the treads are evened out with the perpendicular bars,
28:12it's a sign you need to book an appointment with your local car service.
28:15Since most likely, the tires have lost most of their traction
28:19and may not be safe for driving any longer.
28:22The upper corners of a car windshield feature textured black dots melted into the glass edges.
28:27This neat add-on isn't there for design purposes.
28:31It's called frit glazing,
28:33which means that a special type of ceramic paint is added to the window
28:37for protecting its sealant from UV rays.
28:40It also conceals and creates a coarser surface for the adhesive used to set the window in place.
28:47Whenever you're up for a drive,
28:49check out if there's a small tab under your car's rearview mirror.
28:53Bet you didn't know it's there to help switch the mirror from daytime to nighttime views.
28:59It uses a prismatic glass technology to blur the reflection
29:03and reduce the glare of headlights behind you in traffic.
29:07People came up with these manually tilted mirrors in the 1930s,
29:10but they became standard somewhere in the 1970s.
29:14While you're in the car,
29:15check out the headrests,
29:16as you most likely don't know that they carry a little disguised purpose.
29:21Of course, they're adjustable to accommodate passengers of any height
29:24so that they get the proper support for their heads and necks.
29:27The hidden feature is that they are detachable and come with two very solid metal bars.
29:33Should you ever find yourself stuck in a car and need to make a fast getaway?
29:37These bars come in handy to crack out the car windows.
29:41So you're out for a drive and you're suddenly out of gas.
29:45What I'm about to describe sounds more like a meme than an actual situation bound to happen.
29:49But what if you're in such a hurry that you accidentally drive off with the gas nozzle still in the
29:55tank?
29:55Well, the nozzles have been designed to prevent any hazards from happening, rest assured.
30:01They feature a breakaway device that will allow the hose to separate when taken out with enough force.
30:07Initially designed in the early 20th century to be worn exclusively by basketball players,
30:12sneakers soon became one of those fashion fundamentals, similar to jeans and leather jackets.
30:17If you take a closer look at them, you'll see they have two extra holes on the side, similar to
30:23the shoelace holes.
30:24They're manufactured as such not only to provide extra ventilation,
30:28but to allow people to get extra creative with their laces when wearing the shoes.
30:32Admit it, you've always thought that chopsticks are merged at the end for the sole purpose of keeping them together
30:38until you're ready to dig into your meal.
30:40That may or may not be the whole truth.
30:43Under a more detailed inspection, the wooden tools feature a square-shaped end.
30:47Chopsticks manufactured like this date back to an old Japanese traditional design,
30:52which can help with breaking the ends easily.
30:55The separated end can then be used as a resting block for the chopsticks
30:59to keep it more sanitized in hopes it can be used again,
31:02since they won't be touching the table or any other surface.
31:06Women's bikes have a special design, which, surprisingly, has a historical and fashionable purpose.
31:13The lower frame is for the most part meant to make up for the generally shorter height of ladies,
31:18compared to that of the average gentleman.
31:20While that is the case for handlebars and saddles,
31:23the overall frame is lower for an additional purpose.
31:26Way back when women wore long skirts and dresses all day,
31:30every day they needed to make sure their outfits wouldn't get caught in the frame.
31:34That's how we came up with a lower-framed bicycle,
31:37perfectly made for women and their needs at the time.
31:40The fact that toothpastes are multicolored is not just a nice perk to make dental hygiene more fun.
31:47There's a secret meaning related to each of the colors, which dates back to the 1970s.
31:52In those days, people grew more and more interested in their oral health care,
31:56and as such, they were looking for products which could do more than merely clean their teeth.
32:02One company was the pioneer in that regard,
32:05adding mouthwash to its toothpaste, meaning the blue strip.
32:08They later added on the red strip,
32:11meant to feature ingredients which helped with gum care.
32:14Speaking of toothpaste, check the cap next time you open a new tube.
32:18You may be in for a little surprise.
32:20There's a pointed cone shape inside the cap,
32:23so you can puncture the seal of the toothpaste without cutting yourself or ruining your manicure.
32:28Not to mention, it's more hygienic since you won't be able to transfer germs
32:31or other bacteria into the product itself.
32:35On the subject of bathroom countertop items,
32:38toothbrushes come with a neat add-on hidden in the bristle patterns.
32:42Apart from making the toothbrush look cooler,
32:44they also do come with a practical purpose.
32:47Most toothbrushes come with a pattern of blue bristles intertwined with white ones.
32:52The blue dye is meant to fade out,
32:54signaling the time when you need to replace your toothbrush.
32:58Dentists say that toothbrushes should be replaced every 3 to 4 months,
33:02but it does serve as a great reminder in case you forget.
33:05Still love playing with Lego?
33:07Don't judge.
33:08Hey, it's a great hobby for all ages.
33:10Notice there's a hole on top of the Lego heads?
33:13Behold, you're looking at a safety feature that the people at Lego
33:16designed to prevent choking hazards.
33:19The most dangerous issue should a person swallow any of these pieces
33:23is the blocking of the airways.
33:25Designing a hole inside the Lego head helps the air to flow freely through the piece
33:30until it can be removed safely.
33:33We're now used to all sorts of modern light bulbs,
33:36some tubular, some shaped like diamonds,
33:38and some even twisted altogether.
33:41Historically, light bulbs were round and the initial shape served a purpose in itself.
33:46It was mainly connected to the fact that glass bulbs were hand-blown,
33:50which gave them the round shape to begin with.
33:52The hidden practical reason was that the light bulb filament
33:55needed to be at the same distance from every surface of the glass sphere.
33:59The easiest way to achieve this was to make the glass in the shape of a globe.
34:06You're thirsty, so you crack open a soda can and take a few big gulps.
34:10Next thing you know, you're out of commission.
34:13Turns out, that can was contaminated with something nasty,
34:17like rat urine, and you had no clue.
34:21Just goes to show, you never know what might be lurking in that seemingly innocent drink.
34:27During transportation, storage, or handling,
34:30cans can pick up germs, bacteria, and dirt.
34:32When you drink straight from the can,
34:35those germs can easily enter your body.
34:38Cans are often stored in warehouses
34:40and rarely get a good cleaning before they reach you.
34:43Warehouse conditions can be pretty gross.
34:46Think rats running over them and less than ideal hygiene.
34:51To stay safe, it's a good idea to clean cans before drinking from them.
34:55Experts suggest giving them a quick wash with soap and water to avoid contamination.
35:00Studies have shown that unwashed bottles can be full of bacteria,
35:04so this step is really important.
35:07Now, quick question.
35:09Who's taken out more people?
35:11Sharks or vending machines?
35:14Surprisingly, vending machines have a darker history.
35:17Let's dive in.
35:18But first, let's define what counts as a vending machine casualty.
35:22We'll rule out things like expired snacks or electric shocks.
35:26Those aren't the machine's fault.
35:28What we do count are incidents where someone was severely harmed or, what's worse,
35:33passed away from rocking or tilting the machine.
35:36For sharks, any fatal encounter counts.
35:41In a 1995 report, there were two severe incidents that ended up in demise
35:47and one serious injury linked to vending machines.
35:50Since 1978, there have been at least 37 such incidents and 113 injuries,
35:57which gives us about two fatalities per year.
36:01Compare that to one shark-related incident in 2021.
36:05However, this data is quite old.
36:07But since 2008, there haven't been any reported vending machine incidents.
36:12Why the drop?
36:13It could be due to warning signs and credit card readers reducing the need to shake machines.
36:19But remember, your risk varies based on where you live and your habits.
36:24In the end, the vending machine versus shark comparison isn't quite accurate anymore.
36:29Today, you're more likely to have a serious encounter with a shark than a vending machine.
36:34But the point remains.
36:35Sharks aren't the bloodthirsty hunters they're made out to be.
36:40So, someone pointed out your visible nose hairs and now you're looking for ways to deal with them.
36:45You might think plucking is the way to go, but hold up, it's not as safe as you think.
36:50Here are three solid reasons to avoid plucking your nose hair.
36:55Your nose is full of delicate nerves, follicles, and plenty of bacteria.
37:00Plucking nose hair can damage the sensitive skin inside your nostrils, letting germs in and causing issues like infections and
37:07inflammation.
37:09Also, just like with waxing, plucking nose hair can result in ingrown hairs.
37:14As the hair grows back, it might curl into the follicle, causing bumps, discomfort, and inflammation.
37:20This can lead to folliculitis, which shows up as small, pus-filled red bumps and can be itchy or painful.
37:27In severe cases, plucking nose hairs can cause nasal furunculosis, a deep follicle infection with swelling and discomfort.
37:36This infection can spread to blood vessels near the brain, potentially leading to cavernous sinus thrombosis,
37:43a condition where blood clots form behind the eye sockets.
37:46If not treated, this condition can be life-threatening and may cause permanent brain damage.
37:52To avoid these problems, go for trimming your nose hair instead.
37:56Trimming doesn't make your hair grow back thicker or faster, and it helps maintain the right amount of nose hair
38:01to keep out pathogens.
38:05Contact lenses are meant to help you see, but they can make you turn completely blind.
38:11One big no-no is wearing your contacts in the shower.
38:14It's bad for both your lenses and your eye health.
38:18Showering with contacts is like swimming or sleeping with them in.
38:21It's a common mistake.
38:23Water and contacts just don't mix.
38:26You need to keep your lenses clean to avoid any issues.
38:30If water gets behind your lens, germs or chemicals like chlorine can get in there and cause trouble.
38:36At best, you might end up with sore or itchy eyes.
38:39Worse, you could get conjunctivitis from a bacterial infection.
38:43In rare, serious cases, you might even face infections, which can sometimes lead to blindness.
38:50Most people wear contacts in the shower accidentally rather than doing it on purpose.
38:55If this happens, close your eyes right away and carefully step out of the shower to remove your lenses.
39:00If your eyes feel sore or look red afterward, contact your optometrist, ASAP.
39:07Always use the cleaning solution your optometrist recommends to sterilize your lenses before putting them back in.
39:13But really, it's best to take out your contacts before showering or bathing.
39:18If there's one piece of home decor you should keep a close eye on, it's snow globes.
39:23They might seem harmless, but a family in East Hampton, Massachusetts would beg to differ.
39:28In a crazy turn of events, a snow globe sparked a fire in their apartment while no one was home.
39:35Luckily, quick-thinking neighbors and a swift response from the fire department kept the blaze from spreading through the entire
39:41complex.
39:42It was a normal Thursday morning when, around 11.30 a.m., neighbors heard smoke alarms blaring in the apartment
39:49and dialed 911.
39:51Firefighters arrived to find the place locked, so they had to force their way in.
39:56Inside, they found a small fire on the coffee table and a room filled with smoke.
40:01There, they also saw the culprit.
40:03It was a snow globe.
40:04It was sitting just right on the coffee table, and the sunlight hit it at the perfect angle, magnifying onto
40:11some cardboard and styrofoam and setting them on fire.
40:14While it's not calming, fires started by magnified sunlight do happen.
40:19Many firefighters have seen blazes ignited by mirrors and magnifying glasses.
40:24So, keep those snow globes out of direct sunlight.
40:27Better safe than sorry.
40:32Alright, let's talk about fatal fruit.
40:35No, I'm not going to bore you with another lame list of the most poisonous fruits out there.
40:40Instead, I'm going to tell you about something heavenly tasty that can make you teleport to the heavens in a
40:46matter of seconds.
40:48Meet the coconut.
40:49This seemingly innocent fruit has a dark side.
40:53Coconuts are responsible for around 150 fatalities each year.
40:58These bad boys have a whole page dedicated to the fatal incidents they've caused.
41:03A full-size coconut weighs about 3 pounds 3 ounces.
41:07And if you know a thing or two about physics, you'll understand that gravity makes them even more dangerous when
41:12they fall from trees.
41:14But it's not just falling coconuts you need to worry about.
41:18Consuming large amounts of coconut water can lead to sudden cardiac arrest due to hyperkalemia, thanks to its high potassium
41:26levels.
41:27And while rare, there have been cases of anaphylaxis in people with coconut allergies.
41:32While the most common way coconuts cause harm is by falling and hitting someone, there have been some unusual incidents
41:39too.
41:39In December 1923, a man in Newcastle, Pennsylvania passed away while trying to crack open a coconut with the butt
41:47end of a loaded revolver.
41:49It went off and he was shot in the abdomen.
41:52You know those handy selfie sticks that help you nail the perfect shot?
41:56Turns out, they can be way more dangerous than you'd expect.
42:00These little gadgets have led to a surprising amount of injuries and even some fatalities.
42:05People have accidentally knocked themselves or others out, taken a tumble off cliffs, and even been hit by cars while
42:13trying to get that Insta-worthy pic.
42:16Some popular landmarks have even banned selfie sticks altogether.
42:20For instance, the oceanfront in Mumbai has said no to selfie sticks.
42:24India, by the way, leads the world in selfie-related deaths.
42:28Nearly 40% of the 49 globally recorded fatalities over the past three years happened there.
42:35If you still think selfie accidents aren't a big deal, consider this.
42:39From 2008 to mid-2021, a staggering 379 people lost their lives while trying to get that perfect shot.
42:48So yeah, it's definitely something to take seriously.
42:52Most kitchen shears have metal plier-like teeth in the middle, between the handle grips.
42:57They can help you crack nuts, crab shells, and release other tough products.
43:02You can also open jars and bottles, or remove herb stems with their help.
43:07You can keep your cold meals cold and your food fresh by making a DIY ice pack.
43:13Take a sponge and fill it with water.
43:16Then put it in a plastic bag and leave it in the freezer.
43:19Once the sponge is frozen, it'll stay this way for a long time.
43:23Keep in mind that you should use a watertight bag and a fresh sponge.
43:28If you turn over a Tupperware container, you'll see some symbols.
43:32They'll inform you if you can put the container in the dishwasher, if it can be microwaved or frozen.
43:38You may even find out how you can recycle the thing.
43:43Staplers actually have two modes, not just one.
43:46There's a metal plate on the lower part of the device, which helps bend the staples inward after they've pierced
43:52the paper.
43:52What many people don't know is that you can turn this plate around to switch from the staple mode to
43:59the pinning one.
44:00The pinning setting is for temporary fastening.
44:04The staples bend outward, making them easier to remove when necessary and damaging the paper less, too.
44:11When you take a sip from a coffee cup closed with a lid, the air pressure inside the cup drops.
44:18That's why the air from the outside tries to push into the cup.
44:21The tiny hole on the lid allows some air to enter this way, and the liquid can go out of
44:27the main hole more smoothly.
44:30It's often hard to figure out how much detergent you need to clean your laundry well, but not go overboard.
44:36Pay attention to the cap of your detergent.
44:39It usually has a marker indicating how much product you need to add to your laundry.
44:44Or there might be an instruction on the bottle.
44:47It'll let you know how to measure the detergent.
44:50You can use most screwdrivers together with a wrench to create more torque.
44:55Just place the wrench over the handle of the screwdriver.
44:58This way, you'll need to apply a lot less force than before.
45:02You'll also be able to get to hard-to-reach areas more easily.
45:06The hole in a ruler can be useful if you want to hang the device on a hook.
45:11You can also place a pencil tip in this hole if you need to draw a perfect circle.
45:17Coffee stirring sticks have holes in them because those help reduce the resistance from your drink.
45:23This way, they can stir sugar much more effectively.
45:27Such a design also makes these plastic sticks tougher and prevents them from bending in hot water.
45:33And since stirring sticks are partially hollow, less plastic is used during their production.
45:40Some boxes of chocolates have little dents in between the holes for candies.
45:44If you push such a dent, the chocolates surrounding it will pop out of their compartments.
45:50The small bumps on the F and J keys on the keyboard help people find the right keys without looking
45:57down.
45:57It's especially convenient for those who use touch typing.
46:01The rumble strips on the sides of the road are placed there to alert drivers who doze off behind the
46:07wheel.
46:08When their tires move over these strips, the noise and vibration work like an alarm clock.
46:14The black grate on a microwave is called a Faraday shield.
46:19It contains the electromagnetic energy inside the oven and protects the exterior from radiation.
46:25The grate also speeds up the heating process.
46:29Bottles have long necks so that your drink stays cool longer.
46:33Hold the neck, not the bottle itself, and your drink won't warm up.
46:37Dimples on the surface of a golf ball increase its lift and reduce air resistance.
46:43It means that the ball can go further.
46:45The dimples don't have to be spherical.
46:48They can be hexagonal or have any other shape.
46:52There's a tab on the bottom of your rearview mirror.
46:55If you push it back during nighttime driving, the headlights of the car moving behind yours won't be so blinding.
47:01If you're driving during the day, pull the tab forward.
47:05You can peel an orange more effectively if you cut into the peel at the top and bottom first.
47:11Then make a slit on one side and just pull the peel open.
47:17Headrests in cars are detachable.
47:19You can use one to break the windows if you get stuck in your vehicle.
47:23But by smashing the glass, you can easily hurt yourself.
47:26So try sliding one of the prongs in between the windowpane and the door.
47:31Then pull the headrest towards yourself.
47:33The window will shatter.
47:35But hey, I'd try the door lock first.
47:39Solo cups used at barbecue parties can help you measure liquids.
47:43The bottom line equals one ounce.
47:46The second line means you've poured five ounces.
47:49And the third line means 12 ounces.
47:52Sneakers were originally invented for basketball players.
47:56And since they needed to lace their shoes in the most comfortable way, side holes were invented.
48:01Those helped players lace their sneakers in any way they liked.
48:05And they accommodate anyone's foot.
48:08Little buttons on your jeans are called rivets.
48:11They were originally placed there to prevent the seams from ripping.
48:14In the past, mostly miners and other workers wore jeans.
48:19That's why this item of clothing had to be particularly durable.
48:23And even though these days, jeans aren't under such stress, the tradition of using rivets still remains.
48:30A big toothy spoon comes in handy when you need to pull your spaghetti out of the pot.
48:35And the hole in the middle of this spoon can help you measure portions.
48:40One portion equals as many dry noodles as you can fit into the hole.
48:45Sometimes, pre-rinsing dishes may lead to your dishwasher cleaning them worse than it could.
48:51Special sensors inside modern dishwashers can perceive how dirty your plates are.
48:56And after that, they send a controlled jet of water to wash all that stuff off.
49:01The only thing you're actually supposed to do is remove solid food from your plates and stack them up properly.
49:08Ribbed ketchup containers that they give you at fast food restaurants can get a bit bigger.
49:12Just pull the ribs outward and your container will house much more sauce.
49:18While using a plunger on a clogged kitchen sink or toilet, make sure you've got the right tool.
49:24If it has a standard bowl-shaped rubber head, it's perfect for flat surfaces such as a sink or a
49:30tub.
49:31But the one designed for toilet pipes has a narrower head.
49:36The hole near the rim of your bathroom sink is there to prevent overflows.
49:41Thanks to it, all excess water goes into the siphon.
49:44Plus, it helps your sink drain faster.
49:47The hole gives the air gathered in the siphon somewhere to escape.
49:52The hole in a lollipop stick can save your life.
49:56If the stick gets stuck in someone's mouth, the hole will prevent this person from choking.
50:01But the original reason for it is to simply not let the candy run off the stick.
50:06During production, the liquid treat is poured on top of the stick.
50:10The stick is hollow inside, so the candy gets inside it from both the top and the side, through that
50:16exact hole.
50:17And when it gets solid, it keeps perfectly on the plastic tube.
50:23Most padlocks have a tiny hole on the bottom.
50:26It's needed to drain water from the lock and avoid corrosion.
50:30By the way, it's the best place to lubricate a padlock.
50:34Just put a drop of oil there, and the key will turn much easier.
50:38If you don't see a hole on the bottom, the lock is supposed to be used inside.
