00:00If you look at it on the street, you'll think a fire hydrant is about 3 feet in height.
00:04But the actual size of the device used to provide water supply to firefighters all over the world is twice
00:10as large.
00:11That is, if you count the rest of the hydrant, which is hiding underground.
00:15They're mostly red, and it's not just a matter of urban design.
00:18First of all, they need to be of bright, easily noticeable colors, so firefighters can spot them fast when they
00:23need to.
00:24The choice of color depends on how much water the hydrant can hold.
00:28It can sometimes vary depending on the location, but here's the breakdown.
00:32A red fire hydrant can splash 500 gallons of water per minute, while an orange one, at least 1,000
00:39gallons.
00:41Green ones mostly process 1,500 gallons of water per minute, and the most plentiful ones, colored blue, can generally
00:47contain over 1,500 gallons.
00:50Hey bowling fans, isn't it super annoying when your bowling ball gets cracked?
00:54Turns out that most of them get damaged because of incorrect storage or spikes in temperature.
01:01Now come on and face it, since it's already cracked a bit, aren't you curious what's actually inside the bowling
01:06ball?
01:06Because I sure am.
01:08Let's have a look.
01:09They mostly make the inner core of the ball of powdered metal oxides, like calcium or iron oxide.
01:15Then mix them with some resin and catalyst to harden the whole mixture.
01:19So that light bulb shape you now see inside of the ball is actually its heaviest part.
01:24It also influences how your bowling ball rotates when going down the lane.
01:29The same goes with spray paint cans.
01:31When you shake it, it makes a weird noise, but what is that thing in there?
01:35It's called a pee, and it's meant to hold the paint mixture in place and maintain its shape.
01:40They generally make it out of plastic, metal, or ceramic.
01:43It basically acts as a whisk to make sure your paint is well mixed together before you apply it to
01:49your surface of choice.
01:51Ever wondered how soda bottles keep that refreshing fizz for that long?
01:55Well, they have a little plastic ring fastened to the lid.
01:58They place it there to keep the gas from escaping and making the soda go flat,
02:03even if you shake it around in your bag the whole day.
02:07Speaking of things we use on a hot summer's day, wait, wait, don't put your baseball cap on just yet.
02:12Take a look at it for a minute, and you'll notice there's a small button on the very top.
02:16Is it functional, or is it just there for the sake of design?
02:20Way back when people started using fabrics to cover their heads, some say the button was actually functional.
02:26Since it's on top of the cap where the fabric panels come together,
02:29the top button helps keep the cap crown in one single piece.
02:33Now, with recent advances in fabric and pattern design, the button is more of an aesthetic feature.
02:38It's used to cover up the joint point of the fabric panels.
02:42Your cap might not have a button at all, but don't you think a cap actually looks better with one?
02:47Cotton pads have two sides, and if you take the time to look at them carefully, they're actually different in
02:53texture.
02:54Just in case you've ever wondered why, the textured side is for applying makeup, and the even side is for
02:59removing it.
03:02Bookworms. This one is for you.
03:04Dust jackets that come with a lot of hardcover books are not just meant to make your book look pretty.
03:08They also double as a bookmark.
03:11Just fold the pages you've already read underneath the inside of the jacket, and voila!
03:16Next time you reach out for your favorite shirt, take a look at the top buttonhole.
03:20It should be stitched horizontally, and all the other ones are vertical.
03:25Turns out that the dress shirt was designed this way,
03:27since the first and the last buttons were the first ones to unbutton throughout the day.
03:31They then changed the direction of the buttonhole to ensure the shirt would stay nice and fitted before you're ready
03:37to take it off.
03:39These days, we have so many variations of this awesome dessert,
03:43that it's hard to imagine we've ever lived without it.
03:45You can find different types of cookie dough ice cream, or even chocolate chip cookie cake, basically everywhere.
03:51But the famous cookie wasn't actually invented until 1930.
03:55The story goes that a woman named Ruth Graves Wakefield was preparing some chocolate cookies as she was waiting for
04:01some guests to arrive.
04:02She soon figured out she was out of baker's chocolate, a crucial ingredient for the classic cookies.
04:07To fix things up, she chopped up a block of semi-sweet chocolate,
04:11thinking it would eventually spread out evenly throughout the batter, given the heat of the oven.
04:16Things didn't necessarily go as planned.
04:18But hey, it's great they didn't, because this is how she invented this modern dessert we now can't get enough
04:23of.
04:25And speaking of popular snacks, the potato chip is even younger than the chocolate chip cookie.
04:30Well, at least historically.
04:32There are many stories trying to explain how it was invented.
04:36One of them goes like this.
04:37A chef named George Crumb, based in New York, put the chips together in 1953.
04:43He decided to try a different cooking solution when one of his customers didn't have nice things to say about
04:49his french fries.
04:50He said they were too thick and kind of mushy.
04:53Then, Crumb came up with potatoes that were thinly sliced and fried until brown.
04:58People absolutely loved the dish.
05:01And they welcomed the first ever batch of chips with open arms.
05:05Ice cream, anyone?
05:07If the story is true, back in 1904 at the St. Louis World's Fair,
05:11one ice cream shop owner ran out of cups to serve his dish.
05:14So, he fashioned a waffle into the shape of a cone.
05:18And the rest was history.
05:20Okay, I'll admit it, chewing gum-like treats have been around since the ancient Greeks.
05:25So, this one isn't particularly a revolutionary discovery.
05:28But the actual gum we buy today wasn't there until the late 1800s.
05:33An American inventor named Thomas Adams wanted to mix together different chemicals to create rubber.
05:38He tried and failed, for that matter, to play with Chickle for his experiment, but ended up fashioning this neat
05:45treat.
05:45They still use Chickle to this day to produce most chewing gums.
05:49Back in the 1800s, there lived a man named Jean-Baptiste Jolie, who worked in the fabric industry as a
05:55textile maker.
05:56How he came up with this next invention that we use a lot these days has less to do with
06:01him and more to do with his maid.
06:03The story goes that the woman accidentally knocked a kerosene lamp over onto a tablecloth.
06:09Instead of getting upset over the damaged fabric, Jolie noticed that the substance actually made the material cleaner.
06:16Figured it out yet?
06:17Yep, that's how the idea for the very first dry cleaner popped up.
06:21A very neat accident, if I do say so myself.
06:25Now this one I loved.
06:27Did you know matchsticks were initially called friction lights?
06:30Or at least that's how their inventor, a chemist, named John Walker, called them back in 1826.
06:37He scraped a stick coated in chemicals across his hearth, totally by accident one day, and realized that they ignited
06:44and created a spark.
06:46Initially made out of cardboard, they were then made using wooden splints and sandpaper.
06:52Back in the 1940s, a man named Harry Coover stumbled upon a chemical formulation that seemed to stick to everything
06:59it touched.
07:00The scientific community at the time didn't look much into it as the formula didn't seem to have many applications
07:06back then.
07:07It wasn't until 1951 that he looked a bit more into the formula and decided to repurpose it, along with
07:14a fellow Eastman Kodak researcher named Fred Joyner.
07:17They gave it a proper full name.
07:19But you must know it by the shorter version.
07:22Superglue.
07:24It also has many uses in security these days that it's hard to believe that we didn't come up with
07:29this one on purpose.
07:31Back in 1903, a scientist named Edward Benedictus knocked over a flask by accident.
07:37He looked down and was amazed to see that the glassware had just slightly cracked but maintained its shape.
07:43He was expecting it to break into a million tiny pieces.
07:46Curious about this hidden feature, he looked into it and figured out what was keeping the glass together was a
07:52substance coating the inside of the glass.
07:54Ta-da!
07:55That's how humanity came up with safety glass.
08:00Road and construction workers are usually dressed in orange because the bright orange hue is visible even in bad weather.
08:07It's the most effective color to attract attention and alert people.
08:10No wonder lots of safety jackets and traffic cones are orange as well.
08:14The stop sign has an eight-sided shape to help drivers recognize it easily, even if they see it from
08:20the back.
08:21And when the signs weren't reflective yet, the octagon shape prevented drivers from confusing the stop sign with any other
08:27at night.
08:29The rumble strips on the side of the road are placed there to alert drivers who doze off behind the
08:33wheel.
08:34When their tires move over these strips, the noise and vibration work like an alarm clock.
08:39There are magnetic locks on fuel hoses at gas stations.
08:43They come in handy if someone drives away with the gas nozzle still attached to their car.
08:48In this case, the lock detaches the hose automatically.
08:51Oh, that's embarrassing.
08:53Gasoline looks like a rainbow in a puddle because it can't mix with water.
08:57It forms a thin membrane over it.
08:59When light reflects from it and the water at the same time, you've got a rainbow.
09:05A triple handle on a jerry can is there to make it easier for two people to carry it and
09:10distribute fuel evenly.
09:12Gas cans often have a second hole that actually needs to be uncapped too before you pour the gas.
09:17The air passage will prevent it from pouring out, so no more fuel waste.
09:23Most gas cans have two holes with caps, a bigger and a smaller one.
09:27You're supposed to uncap the smaller hole before pouring gas inside the bigger one.
09:31It'll prevent the liquid from glugging and spilling all over your clothes and the ground.
09:37Another little thingy we often neglect is a point on an ointment cap.
09:40Most tubes are usually sealed with a plastic film or a foil, and opening it with your fingernails isn't the
09:47best idea.
09:48A point easily opens even the most safely sealed tube.
09:52You can use most screwdrivers together with a wrench to create more torque.
09:57Just place the wrench over the handle of the screwdriver.
10:01This way, you'll need to apply a lot less force than before.
10:04You'll also be able to get to hard-to-reach areas more easily.
10:09They install cameras in shops, banks, and hospitals to monitor everything.
10:13If something happens, you can call the police or rescuers.
10:17The camera really helps to solve a lot of problems.
10:20Why are there no cameras on planes?
10:23The crew keep order on the plane, but they won't be able to do anything if something serious happens.
10:28Besides, there's nowhere to run on the plane.
10:31During the flight, the cameras are useless, and after the flight,
10:35the words of the passengers work ideally instead of cameras.
10:39So, if cameras do no good, then why spend money on them?
10:43Water is great at cleaning stuff because it has triangular molecules.
10:47They're made of one oxygen and two hydrogen atoms, um, H2O?
10:52Such molecules have slightly different charges on their opposite sides, pretty much like magnets.
10:57That's why water easily sticks to other molecules, including those that make up dirt.
11:02Lots of private houses have triangular-shaped roofs because this allows rain, snow, and fallen leaves to slide off the
11:09slope.
11:09If all this stuff piled up on top of your house, one day, your roof would collapse.
11:15When a storm is coming, clouds seem to turn dark, but it's just an illusion.
11:20Thin clouds on a sunny day let the light through easily.
11:23They also scatter all the colors of the light spectrum.
11:26This makes us perceive the clouds as white, but the thicker the clouds are and the more water droplets they
11:32contain,
11:33the less light they let through and the darker they look.
11:36A good doorknob is the one made of brass, bronze, or some copper alloys.
11:42These metals have an anti-germ effect.
11:45Bacteria spread way slower on them.
11:47They also get rid of germs pretty fast, within a couple of hours.
11:51Nope, it doesn't mean you don't have to wash your hands.
11:55Diamonds have such symmetrical shape to show you their brilliance.
11:59Initially, the gems aren't so beautiful.
12:01They go through several stages of cutting, and then become pieces of elegance.
12:06Most of these stones have a round shape with slightly pointed corners.
12:10Diamonds shine the brightest in this shape.
12:14Why are there two holes in the socket?
12:16The left hole is neutral, the right hole is not, and the gap underneath is ground.
12:22Electricity needs to flow through the chain.
12:25The current flows from the hot slot, passes through your phone charger, for example,
12:29and then goes through the neutral hole.
12:32Ever wondered what that small pocket on your jeans is for?
12:35People used to wear watches on chains.
12:38That small pocket was meant for it.
12:40Now, almost no one wears such a watch, but the pocket remains.
12:44You can still keep something small in there, like a ring.
12:47In London, there are some poles that look like street lamps, but there are no bulbs.
12:52Well, their official name is stink pipes, and they're a thing of the past now,
12:57but they used to come in handy back in the 19th century.
13:00These hollow poles would vent away the air and explosive gases with bad smells to prevent,
13:06shall we say, unwanted consequences.
13:09Most kitchen shears have metal, plier-like teeth in the middle.
13:13Between the handle grips, they can help you crack nuts, crab shells, and other tough products.
13:18You can also open jars and bottles or remove herb stems with their help.
13:24Leather often looks dull to the eye because it's covered with itsy-bitsy scratches and scrapes.
13:29They scatter the light that hits the material.
13:31When you coat your shoes in a layer of wax, you fill these tiny crevices.
13:35The surface becomes smoother, and the rays of light bounce off it more evenly.
13:40That's why the leather looks shiny.
13:43Highlighters are filled with a special semi-transparent fluorescent ink that can glow in dim light.
13:50Yellow and light green hues are the most popular
13:53because they don't prevent you from seeing the text after black-and-white photocopying.
13:58Photocopiers perceive yellow and light green marks as very pale and don't print them.
14:02They make magnets shaped as a horseshoe because this increases the magnetic force.
14:08Colors matter too.
14:09The blue part indicates the south pole.
14:12The red part, the north pole.
14:14The two poles work simultaneously and increase the attraction force.
14:19The dime-sized holes in elevator doors is actually a keyhole.
14:23If the doors get stuck, an operator can open them manually thanks to this hole.
14:28They'll just insert a special key.
14:31The tiny hole in the airplane window is there to balance air pressure.
14:35The window has three layers.
14:37The outer pane is extremely sturdy.
14:40It can withstand air pressure differences during takeoff and landing.
14:44The inner pane, which is the closest to you, is made of cheaper materials.
14:48It prevents potential damage to the window.
14:50The hole itself is in the middle pane.
14:53It not only balances the pressure, but also prevents the window from fogging.
14:59Escalator brushes are there for your safety.
15:01They don't allow you to come too close to the edge of the escalator.
15:05This way, your clothes won't end up between the steps.
15:08You see the sun as yellow or orange.
15:11Because the atmosphere of our planet scatters such colors as blue, green, and violet.
15:16This is also why the sun looks warmer at sunrise and sunset.
15:21Go shopping for some oranges and I'm sure you'll get them in a red mesh bag.
15:25You'll rarely see them lying around without one of those.
15:28It's pure marketing, and that color isn't a random choice.
15:32When packed in a red mesh bag, oranges appear more orange, fresher, and more appealing to you.
15:38So, you're more likely to buy them, right?
15:41Lemons are usually sold in green mesh bags for a similar reason.
15:45If you pack them in red, they'll appear more orange.
15:48Green goes better with yellow, and makes those lemons stand out.
15:52Mattress manufacturers make a limited number of different mattresses,
15:56and the only way to make them look different is to come up with a fancy stitching pattern.
16:01Two mattresses of two different companies might be the exact same quality, but cost differently.
16:06Most people will never know it, and will decide that different patterns mean something in terms of quality.
16:12So, when shopping, don't mind the pattern at all.
16:16Almost all hotels have white bedsheets.
16:19They choose this color specifically to show how high their standards of cleanliness are.
16:23The whiter and brighter the sheets are, the more luxurious the hotel seems.
16:27It's much easier to see dirt and stains on white linen.
16:31It's like proof that you've checked into a clean room.
16:34Most kitchen shears have metal plier-like teeth in the middle, between the handle grips.
16:39They can help you crack nuts, crab shells, and release other tough products.
16:44You can also open jars and bottles, or remove herb stems with their help.
16:49You can keep your cold meals cold and your food fresh by making a DIY ice pack.
16:55Take a sponge and fill it with water.
16:58Then put it in a plastic bag and leave it in the freezer.
17:01Once the sponge is frozen, it'll stay this way for a long time.
17:06Keep in mind that you should use a watertight bag and a fresh sponge.
17:10If you turn over a Tupperware container, you'll see some symbols.
17:15They'll inform you if you can put the container in the dishwasher, if it can be microwaved or frozen.
17:20You may even find out how you can recycle the thing.
17:25Staplers actually have two modes, not just one.
17:28There's a metal plate on the lower part of the device, which helps bend the staples inward after they've pierced
17:34the paper.
17:35What many people don't know is that you can turn this plate around to switch from the staple mode to
17:41the pinning one.
17:42The pinning setting is for temporary fastening.
17:46The staples bend outward, making them easier to remove when necessary and damaging the paper less, too.
17:53When you take a sip from a coffee cup closed with a lid, the air pressure inside the cup drops.
18:00That's why the air from the outside tries to push into the cup.
18:03The tiny hole on the lid allows some air to enter this way, and the liquid can go out of
18:09the main hole more smoothly.
18:12It's often hard to figure out how much detergent you need to clean your laundry well, but not go overboard.
18:18Pay attention to the cap of your detergent.
18:21It usually has a marker indicating how much product you need to add to your laundry.
18:26Or there might be an instruction on the bottle.
18:29It'll let you know how to measure the detergent.
18:32You can use most screwdrivers together with a wrench to create more torque.
18:37Just place the wrench over the handle of the screwdriver.
18:40This way, you'll need to apply a lot less force than before.
18:44You'll also be able to get to hard-to-reach areas more easily.
18:49The hole in a ruler can be useful if you want to hang the device on a hook.
18:53You can also place a pencil tip in this hole if you need to draw a perfect circle.
19:00Coffee stirring sticks have holes in them because those help reduce the resistance from your drink.
19:05This way, they can stir sugar much more effectively.
19:09Such a design also makes these plastic sticks tougher and prevents them from bending in hot water.
19:15And since stirring sticks are partially hollow, less plastic is used during their production.
19:22Some boxes of chocolates have little dents in between the holes for candies.
19:26If you push such a dent, the chocolates surrounding it will pop out of their compartments.
19:32The small bumps on the F and J keys on the keyboard help people find the right keys without looking
19:39down.
19:39It's especially convenient for those who use touch typing.
19:43The rumble strips on the sides of the road are placed there to alert drivers who doze off behind the
19:49wheel.
19:50When their tires move over these strips, the noise and vibration work like an alarm clock.
19:56The black grate on a microwave is called a Faraday shield.
20:01It contains the electromagnetic energy inside the oven and protects the exterior from radiation.
20:07The grate also speeds up the heating process.
20:11Bottles have long necks so that your drink stays cool longer.
20:15Hold the neck, not the bottle itself, and your drink won't warm up.
20:19Dimples on the surface of a golf ball increase its lift and reduce air resistance.
20:25It means that the ball can go further.
20:28The dimples don't have to be spherical.
20:30They can be hexagonal or have any other shape.
20:34There's a tab on the bottom of your rearview mirror.
20:37If you push it back during nighttime driving, the headlights of the car moving behind yours won't be so blinding.
20:43If you're driving during the day, pull the tab forward.
20:47You can peel an orange more effectively if you cut into the peel at the top and bottom first.
20:53Then make a slit on one side and just pull the peel open.
20:59Headrests in cars are detachable.
21:01You can use one to break the windows if you get stuck in your vehicle.
21:05But by smashing the glass, you can easily hurt yourself.
21:09So try sliding one of the prongs in between the windowpane and the door.
21:13Then pull the headrest towards yourself.
21:15The window will shatter.
21:17But hey, I'd try the door lock first.
21:21Solo cups used at barbecue parties can help you measure liquids.
21:26The bottom line equals one ounce.
21:28The second line means you've poured five ounces.
21:31And the third line means 12 ounces.
21:34Sneakers were originally invented for basketball players.
21:38And since they needed to lace their shoes in the most comfortable way, side holes were invented.
21:43Those helped players lace their sneakers in any way they liked.
21:47And they accommodate anyone's foot.
21:50Little buttons on your jeans are called rivets.
21:53They were originally placed there to prevent the seams from ripping.
21:56In the past, mostly miners and other workers wore jeans.
22:01That's why this item of clothing had to be particularly durable.
22:05And even though these days, jeans aren't under such stress, the tradition of using rivets still remains.
22:12A big toothy spoon comes in handy when you need to pull your spaghetti out of the pot.
22:17And the hole in the middle of this spoon can help you measure portions.
22:22One portion equals as many dry noodles as you can fit into the hole.
22:27Sometimes, pre-rinsing dishes may lead to your dishwasher cleaning them worse than it could.
22:33Special sensors inside modern dishwashers can perceive how dirty your plates are.
22:38And after that, they send a controlled jet of water to wash all that stuff off.
22:43The only thing you're actually supposed to do is remove solid food from your plates and stack them up properly.
22:50Ribbed ketchup containers that they give you at fast food restaurants can get a bit bigger.
22:55Just pull the ribs outward, and your container will house much more sauce.
23:01While using a plunger on a clogged kitchen sink or toilet, make sure you've got the right tool.
23:06If it has a standard bowl-shaped rubber head, it's perfect for flat surfaces, such as a sink or a
23:13tub.
23:13But the one designed for toilet pipes has a narrower head.
23:18The hole near the rim of your bathroom sink is there to prevent overflows.
23:22Thanks to it, all excess water goes into the siphon.
23:27Plus, it helps your sink drain faster.
23:29The hole gives the air gathered in the siphon somewhere to escape.
23:34The hole in a lollipop stick can save your life.
23:38If the stick gets stuck in someone's mouth, the hole will prevent this person from choking.
23:43But the original reason for it is to simply not let the candy run off the stick.
23:48During production, the liquid treat is poured on top of the stick.
23:52The stick is hollow inside, so the candy gets inside it from both the top and the side, through that
23:59exact hole.
23:59And when it gets solid, it keeps perfectly on the plastic tube.
24:05Most padlocks have a tiny hole on the bottom.
24:08It's needed to drain water from the lock and avoid corrosion.
24:12By the way, it's the best place to lubricate a padlock.
24:16Just put a drop of oil there, and the key will turn much easier.
24:20If you don't see a hole on the bottom, the lock is supposed to be used inside.
24:25Instead of opening a banana at the stem, turn it upside down and peel it from the bottom.
24:31It opens much more easily this way.
24:34A utility knife can serve you much longer than you might think.
24:38Look at the blade carefully.
24:40It's made of parallel sections.
24:42Once the knife gets blunt, you should break off the top section.
24:46You can do it with the help of the cap you'll find at the bottom of the instrument.
24:50In no time, you'll have a sharp blade again.
24:53The stripes on headphone jacks keep the wires insulated from one another.
24:58One stripe means the headset has a mono signal.
25:01Two stripes indicate you'll have stereo sound.
25:04And three stripes means the headset also has a built-in microphone.
25:09You can usually find some silica gel in bags, shoes, and many other things you buy.
25:14This gel absorbs excess moisture.
25:17Don't throw it away.
25:18Every time your shoes get wet, put some packets of silica gel inside them.
25:23It's very convenient to use bread tags to organize your cords.
25:27Just take a bread tag and several cords and clip them together.
25:31You can also write notes on these tags and use them as reminders.
25:38Sometimes, when you type big text on your phone, it's pretty hard to get the cursor where it needs to
25:43be.

25:46Simply hard-press the space bar and now you can move the cursor wherever it needs to go.
25:51Voila!
25:54You can get bite-sized pineapple pieces without using a knife.
25:57At least that's what this viral TikTok tip is promising.
26:01First of all, twist off the top of the pineapple, that part which has green leaves.
26:06It's pretty easy.
26:07Just grab it and make several twists.
26:10Then pick the pineapple up and pound it down on the kitchen table.
26:14Repeat the pounding for about five times to make sure you did it sufficiently.
26:19Now you're going to need some arm strength.
26:21Roll the pineapple back and forth while pressing down on it.
26:24The weight is supposed to help separate the core from the fruit.
26:28But beware, if your pineapple is very ripe, it might start to release juice.
26:33Now, gently hold the pineapple skin, pull out one of its scales, and enjoy your snack.
26:39If you've done everything right, you're supposed to be able to pull out a bite-sized piece that will separate
26:44from the core quickly.
26:45Mmm.
26:47Here's another game-changing tip for your kitchen.
26:50Get a habit of storing the cling wrap in the freezer.
26:53When the wrap is cold, it's less sticky and much easier to unroll and use.
26:58You're welcome.
27:01We usually place these non-slit bathtub mats on the bathtub's surface to prevent falls.
27:06But when you're not using the bathroom, you can stick or hang them on the wall.
27:11This way, the mat will get dry way faster, and you'll prevent the accumulation of soap and dirt leftovers on
27:17the bottom of the bathtub or shower.
27:21Gather your shower curtain into a single bundle and tie it into a big knot.
27:25This way, it won't create obstacles when trying to clean the bathtub.
27:31Remember those mysterious stripes on bathroom towels?
27:34It's not just a decoration.
27:36It's a stabilizer strip to help the towel last longer.
27:40Stripes help keep the towels fluffy by limiting the shrinkage every time you wash them.
27:45Therefore, the towel retains its shape, size, and flexibility over time.
27:51They're also handy when you need to dry and clean a narrow and hard-to-reach place where the thick
27:56part doesn't work because it's too fluffy.
27:59For example, the space between your toes or behind your ears.
28:05Also, the stripes help to sort towels by type.
28:08Otherwise, all the towels of the same color and texture would look alike.
28:12You can see the stripes when you fold the towels properly, so it's easier to differentiate.
28:17This way, you can keep all the towels together in a linen closet.
28:21Your family members will never confuse their own towels with someone else's.
28:27Are you sure you know how to use this flat paper box with matches?
28:31You just have to take a match and slide it across the striking surface, right?
28:36Turns out, there's another way.
28:38Put the matchstick head on the striking surface, close the box, and pinch it.
28:43Then, pull the match out with one quick and confident movement, and it should light up.
28:50By the way, when you light up a matchstick or a candle in a dark room, the flames don't have
28:55shadows.
28:56Did you know that?
28:59The circle on the plastic jug of milk can tell you if the milk is good or bad.
29:03So when the circle is inside, take this as a good sign.
29:07And when it pops out, it means that the milk is expired.
29:12Also, the circle helps to keep the jug from blowing up if you drop it.
29:15When it hits the ground or any other surface, the ring will expand to keep the milk inside the plastic.
29:21And if you leave milk in the fridge for too long, it will develop gases.
29:25In this case, the circle will prevent the jug from popping inside the fridge.
29:30When it comes to plastic bags with frozen food, we usually cut off a strip from the top to open
29:36the package.
29:36But you don't have to throw the strip in the trash right away.
29:39You can tie the bag with the remaining food and put it back in the freezer.
29:45Let's say you're driving a car through the night.
29:47Suddenly, some annoying driver behind you with the brights on gets closer and spoils the party.
29:53You can flip this little tab on your rearview mirror and make the bright lights fade away.
29:57In fact, this little mirror that looks flat is a so-called prismatic wedge.
30:03What looks flat is an angled mirror with a wedge of glass.
30:07When you switch the mirror to dim mode, you change the angle of the mirror so it reflects more light.
30:14Here's a cool safety tip when you have to park your car at some risky spot at night.
30:18Pull out the driver's seatbelt, put it through the door handle, and fasten the belt as usual.
30:24This way, you'll ensure that nobody can get in during the night.
30:27Even if they succeed in getting the door unlocked, they still won't be able to come in.
30:33If your car got frozen on a cold winter night and the glass is covered with ice, you can clean
30:38it using the following tip.
30:40You don't need any special cleaning brush.
30:43Just fill a big sealable plastic bag with hot water and wipe the bag over the car to defrost the
30:48ice.
30:49Now, wipe off the remaining water with a rag and you're ready to hit the road.
30:55Everyone knows how to hang a sweater, right?
30:58Well, there's a better way that helps avoid the shoulder pimples that arise when the hanger doesn't fit your clothes
31:03perfectly.
31:04Put your sweater flat on your bed and fold it in half, like this.
31:08Then, place the hanger on the sweater on a diagonal, like this.
31:12Remember that the hanger hook should be under the arm.
31:15Now, grab the arms and fold them across the hanger.
31:19And then, hold the body of the sweater and fold it across in the same manner.
31:24Congratulations! Now you know the perfect way to hang your sweater.
31:29If you're out of staples, you can just turn your stapler over.
31:32And there's a secret little compartment where you can put a whole row of extra staples.
31:36And now you can just conveniently put it into your stapler and go on with your work.
31:43There's a big chance that your oven door is removable.
31:47This way, you can clean it between the glass.
31:49Of course, the mechanism may differ depending on the model.
31:52So, first of all, check the lower corners of the door.
31:55And you'll probably find two screws that will help you lift the door up and then put it back where
32:00it belongs.
32:02Here's a hilarious tip for peeling boiled chicken eggs.
32:06Remove some shells from the top of the egg.
32:09About the size of a small coin.
32:11Then, break up the bottom of the egg.
32:13And now, blow into the top hole as if you're blowing a balloon.
32:18The peeled egg should pop out of the bottom.
32:21Just make sure the eggs are hard-boiled.
32:25If you have a basic electric screwdriver, you can order special brush heads.
32:29Your cleaning routine will never be the same again.
32:33This device will help you quickly and easily clean the dirtiest tiles and gaps between them.
32:38Just spray some bath cleaner and let your screwdriver brush remove all the impurities.
32:43Although this simple tip is very satisfying,
