00:00A label on your panties digging into your most sensitive spots is definitely not the best feeling.
00:06Sure, you can cut it off, but often that just leaves even sharper corners that can be more annoying.
00:12But what if you've been cutting those labels wrong this whole time?
00:15Check it out. On the left, the label is sewn into the seam, while on the right, it's just hanging
00:21on by a couple of threads.
00:23Just snip those threads, and voila!
00:26It's like the label was never even there.
00:28Plus, with this little hack, you can always pick panties in the store that are guaranteed to be comfy.
00:34If you've traveled to Europe recently, you may have noticed how nasty the bottle caps have become.
00:40Yeah, according to the law, they now have to scratch your nose.
00:44Oops, sorry, they have to be attached right to the bottle.
00:47If these bottles annoy you too, try this.
00:50Once you open the bottle, rotate the cap 90 degrees, and pull until one of the plastic connections breaks.
00:56And finally, turn the bottle until the cap touches your chin, not your nose, and drink.
01:03You've been using the colander in the wrong way all this time.
01:06This smart kitchen device has a hidden function.
01:09The traditional way of draining noodles involves dumping boiled noodles into a colander, right?
01:15But if your colander is about the same size as your pot, try this instead.
01:20Place the colander on top of the pot with the noodles, like a lid, and drain the water out.
01:26This method is faster and less messy, and it keeps your noodles in the pot where they belong.
01:33Toilet plungers and sink plungers are quite different, and the toilet version has a handy rubber flap called a flange
01:40that pops out from the cup.
01:42This flange fits snugly over toilet drains, giving you strong suction to tackle stubborn clogs.
01:49While a sink plunger won't help with toilet troubles, the toilet plunger can work on your sink or tub.
01:55Just make sure to keep that flap tucked inside the cup.
01:59And don't forget to give it a thorough clean with bleach before switching from toilet to sink use.
02:04You definitely don't want to mix things up.
02:07If you still work in an office, next time you print out something, make sure to check out this stapler
02:13built right into the printer.
02:15It can staple all the documents that fit in the slot at the same time.
02:19By the way, it's not something new.
02:21Such printers have been around since the 90s.
02:25Why buy a ruler and spend your hard-earned dollars if you can simply use a dollar bill to measure
02:31whatever you want?
02:32Only as long as this whatever is somewhere around 6 inches.
02:37A dollar bill is just about this size.
02:41Even though many people are sure that those tiny holes on the bottom left side of your iPhone are the
02:47speaker, they're actually a microphone.
02:49And speaking of iPhones, if you've got one of the latest models and your phone is out of juice but
02:54there's no socket to be found nearby, here's a nifty trick.
02:58Grab a double-ended charger cord and connect it to another iPhone 15.
03:04Boom! Your phone gets a little power boost.
03:07I bet you've noticed that the hook on a tape measure is a little loose.
03:11Well, that's intentional.
03:12The hook moves just enough to account for its own thickness, ensuring both inside and outside measurements are accurate.
03:20So, if you ever thought it was broken, nope, it's just doing its job.
03:24As for the hole at the end, it's replacing the tape on the edge of a nail to get measurements
03:29from odd spots.
03:31The pockets on new suits are sewn shut to keep the jacket's shape during transportation and display.
03:38Of course, you can unpick them to use the pockets, but you need to be careful with what you put
03:43there.
03:43Anything heavy can easily distort the suit's shape.
03:46The important thing, though, is to remember to cut the threads holding the back vents together for better movement and
03:53comfort.
03:53Oh, and remember to cut those tacky stitches that fasten your new coat's vent, that flap on the back.
04:01Now, that sink squeegee thing actually hides a big secret.
04:05It can store water.
04:07Many sink squeegees have tiny holes that allow water to stay inside.
04:12But why would we need that water?
04:14Oh, you can release it as you squeegee, which will help you rinse the sink as you clean it.
04:21Here's a travel tip that will help you understand U.S. highways.
04:24In the U.S., highways with even numbers run east-west, and those with odd numbers run north-south.
04:32If a highway number starts with an odd digit, it's a spur, which means it doesn't reconnect to the main
04:38highway.
04:38If it starts with an even digit, it's a loop around or through a city that eventually reconnects with the
04:44main highway.
04:46And finally, numbers divisible by five are major highways meant for cross-country travel.
04:53Your iPhone camera can also translate laundry symbols, identify plants, and even recognize some bird species.
05:02It's like having a mini-encyclopedia in your pocket.
05:05Another trick.
05:06When using the markup feature while editing your photos, you might want to highlight a part of a picture.
05:12Put a circle around the needed area and keep your finger pressed down at the end of the stroke.
05:18Voila!
05:19Instead of a misshapen circle, you get a perfect one.
05:22It also works for squares, triangles, and stars.
05:26Barilla, probably the most famous pasta in the world, has teamed up with Spotify to create playlists that match the
05:33cooking time for different pasta shapes.
05:35Just start the playlist when you drop the pasta into boiling water, and when the music stops, your pasta is
05:42ready.
05:44Toasters have crumb trays at the bottom that you can and should clean regularly.
05:49Just slide it out and dump the crumbs.
05:52It's an easy way to keep your toaster clean and working well.
05:56You can use Google Maps to share your location in real time.
06:00Just tap your account icon, select Location Sharing, and choose how long to share.
06:05Your friends can track your progress and be ready when you arrive.
06:09You can also save your parking location by clicking the blue dot.
06:14Do you know that the knobs on some ovens have calibration screws on the back?
06:19You can adjust them to get more accurate temperature control.
06:22It'll definitely help you avoid overcooking or undercooking your meals.
06:27In non-prepaid gas stations in the U.S., try pressing Enter before swiping your debit or credit card.
06:34It'll take you to the prepaid screen, and you can enter the amount you need manually.
06:40If you're drinking outside on a windy day, place some coins in an empty cup, and then put the cup
06:46you're drinking from inside the first one.
06:49The weight of the coins will help you keep your drink from getting blown over.
06:53Simple, but effective.
06:56Once you've peeled your potato, you might spot some tiny divots, known as eyes, that still have some skin on
07:03them.
07:03Many peelers come with a handy scoop designed to tackle these little guys.
07:07Just take the scoop, dig in, and pop them out.
07:10Easy peasy.
07:11Your favorite potato recipe will be totally eye-free in no time.
07:17A cell phone's camera can help you to figure out whether your remote is working.
07:22The camera is sensitive to infrared, so you just need to turn it on and point the remote at the
07:27camera while pressing the remote's buttons.
07:30You'll see the LED flashing in response.
07:33If you spot nothing, something is definitely wrong with the remote.
07:38Bonus fact here.
07:39White vinegar isn't just for cooking.
07:41It's also the real laundry hero.
07:44If you add it to your laundry, it'll take out all the bad smells from your clothes.
07:49The amount to add can be anywhere from a splash to a cup during the wash.
07:54And don't worry about the vinegar smell.
07:56It washes away completely, leaving your clothes fresh.
07:59It's also great for removing hard water buildup.
08:04You must have noticed those lines on some kinds of chips.
08:08For one thing, they help with the distribution of spices and seasonings.
08:12In other words, all those substances that make your chips taste like cheese are mostly stored inside the lines.
08:20Plus, the lines make chips crunchier.
08:24Some cars have a tiny coffee cup sign on their dashboard.
08:28It's the vehicle's anti-drowsiness mechanism.
08:32There are manufacturers that equip their cars with a drowsiness detection system.
08:37It analyzes the speed, wheel angle, and lane deviations to figure out if it's time for the driver to take
08:44a break.
08:45If it is, the vehicle makes several audio signals and the coffee cup sign starts to flash.
08:53Some plastic milk containers have dents on their sides.
08:56These dents serve several purposes.
09:00For one thing, when milk spoils, this process usually causes swelling and high pressure buildup inside the container.
09:08That's when the dent comes in handy.
09:10It pops out and doesn't let the jug blow up.
09:14Plus, if you decide to freeze the milk, it will expand like any other liquid.
09:19And then again, the indentation will pop out and prevent the container from breaking inside your freezer.
09:26You might have wondered why jerrycans have three handles.
09:30It's a clever designer move.
09:33This way, if you carry the container alone, you can use only the central handle to distribute the weight evenly.
09:41But if your friend wants to help you out, each of you can grab the side handle.
09:47The first jeans had a problem.
09:49Workers and miners, who were the original jeans wearers, put too much pressure on the poor piece of clothing.
09:56As a result, the seams couldn't withstand the stress and tore.
10:01Tiny metal studs were invented to prevent this from happening.
10:07Sticky notes come off relatively easily because their adhesive is spread out across the paper unevenly, in small blobs.
10:15And only some of these blobs touch the surface of whatever you've stuck the note on.
10:19That's why when you unstick a post-it and attach it to something else, it still works.
10:25Until all the glue gets used or covered with dirt.
10:29Soda bottles are always filled in such a way that there's some space between the liquid and the cap.
10:36That's because soda contains carbon dioxide.
10:40It's a gas that can expand once a bottle is heated.
10:43If there's no gap in the bottle, it can break because of the pressure building inside.
10:49Also, when you open your drink, the gases go out in the form of bubbles, and the drink is likely
10:55to overflow.
10:56Oh, the gap helps with this problem, too.
11:01Dental floss is super useful for your teeth, but it might be rather hard to operate.
11:06It regularly slips out of your fingers and tangles.
11:10To avoid these problems, tear off a piece of dental floss and tie its two ends together.
11:16It'll be much easier to use and won't hurt your fingers.
11:21Now, about those horizontal lines on plastic bottles.
11:25They help hold bottles up.
11:28Some bottles are produced from soft plastic.
11:31Without the lines, they wouldn't keep their shape.
11:34Instead, they would twist easily or even break.
11:40The soft, round part under a soda bottle cap keeps the carbonation from escaping.
11:45Without it, your pop would go flat in no time, probably even before you buy it.
11:53If you don't have anywhere to put a toothpick after using it, break off its flat end at the first
11:59groove and place it on the table.
12:01Now, you can balance the used portion of your toothpick on the grooved part so that it doesn't have to
12:06touch the table.
12:09You can also make a makeshift stand for disposable chopsticks.
12:13They have a sort of lump on one side.
12:16Break that lump off before you split the pair.
12:20Now, when you want to take a sushi break, just place the stick on this stand.
12:27Donuts are shaped like rings because, otherwise, they might get overdone at the edges, but uncooked and gooey inside.
12:35With a hole in the center, both the outside and the inside get ready at the same time.
12:43Ever notice that layer of clear fluid in gel pens?
12:47It's called the ink follower, or stopper fluid.
12:51The gel in such pens contains pigment particles dissolved in a polymer solution.
12:57The gel should be thick enough to keep the pigment particles suspended, but also thin enough to flow first onto
13:03the ball and then the paper.
13:06The main task of the stopper fluid is to be a barrier to prevent the gel from evaporating or leaking
13:12out.
13:13Without this transparent fluid, your gel pen wouldn't function.
13:18The fluid always stays in one position and doesn't get dissolved with the gel.
13:23Neither does it move backward or flow out of the pen.
13:28Some button-down shirts have a button hidden on the back of the collar.
13:32Its main purpose is to prevent the tie from sticking out from under the collar.
13:38As for that locker loop on the back, you can use it to hang the shirt on a hook to
13:45avoid wrinkling it.
13:47Outer rings and zipper sliders, especially when two sliders are used together, are added so that you can connect them
13:54with a lock and keep sticky fingers away.
13:59Most ambulance cars have this word printed on the front of the vehicle.
14:07It's written in reverse so that the driver in front of the ambulance can see the word properly in their
14:12rearview mirror.
14:14Then they can move out of the way and let the ambulance pass.
14:19Escalator brushes serve an important safety purpose.
14:23You might have heard that most accidents happen after people get their bags or clothes stuck in escalators because they
14:30stand too close to the sides.
14:32But when there are nylon brushes on both sides, you can't but keep your feet away from the escalator's skirt
14:38panels.
14:39The result? No accidents.
14:42The side holes in sneakers are for laces.
14:46Since sneakers were originally invented for basketball players, this interesting design allowed them to accommodate any player's foot.
14:55They just needed to lace their sneakers in the most comfortable way for them.
15:00The holes in the bottoms of your earphones allow air to circulate up and through the speakers.
15:07It helps to increase low frequencies, making the bass sound deeper.
15:11The quality of the sound also becomes much better.
15:16Ever been stranded with a cup of applesauce, but no spoon at hand?
15:21But each snack pack already has a built-in spoon.
15:25Several twists of the foil lid, and here you go!
15:30Diamond slits on backpacks were originally placed only on traveler bags.
15:35Their purpose was to carry ropes.
15:39These days, you can find such slits on almost every backpack.
15:43Why not use them to carry a bottle of water, an umbrella, or a pair of sneakers?
15:50Highlighters are filled with a special semi-transparent fluorescent ink that can glow in dim light.
15:57Yellow and light green hues are the most popular because they don't prevent you from seeing the text after black
16:03-and-white photocopying.
16:06Photocopiers perceive yellow and light green marks as almost non-existent and don't print them.
16:13A stop sign has an octagonal shape to help drivers recognize it easily, even if they see it from the
16:19back.
16:20When the signs weren't reflective yet, this shape prevented drivers from confusing the stop sign with any other at night.
16:28The number 57 on a Heinz ketchup bottle has nothing to do with the product label.
16:34The truth is that the place with the numbers is the very sweet spot you should tap to get the
16:40ketchup flowing.
16:42So, stop hitting the bottom of your sauce bottle and hit 57.
16:48Lots of private houses have triangular-shaped roofs because this allows rain, snow, and fallen leaves to slide off the
16:56slope.
16:57If all this stuff piled up on top of your house, one day, your roof would collapse.
17:05Airplane windows have rounded edges, and that's a crucial safety measure.
17:09It prevents aircraft accidents.
17:12Weak spots are usually situated in the corners.
17:16If airplane windows were square or rectangular, each of them would have four potential weak spots.
17:22Under pressure, they would collapse.
17:26Trains used to make people mad.
17:28During the Victorian era, there was this rumor that the swaying motion of train carriages made passengers, especially men, go
17:36a bit crazy, leading to some strange and dangerous behavior.
17:41The so-called railway madness was supposedly triggered by the noise of the train.
17:46To make things worse, carriages were locked for privacy reasons back then, so people found themselves stuck in tiny spaces
17:53with lunatics who could snap at any moment.
17:58If you see someone putting ketchup on some car, it doesn't mean you're witnessing them preparing a prank.
18:05It means they're just taking care of their car.
18:09Yup, it goes great with hamburgers and hot dogs, but it goes even better with cars, since it has ingredients
18:16that are good at removing rust.
18:18Rust occurs when the metal gets exposed to moisture, oxygen, and heat, and due to weather conditions, it's hard to
18:26avoid it.
18:27When you leave rust for a longer time and don't deal with it, it will continue to degrade the metal.
18:34So, you need to get rid of it before your car becomes physically useless.
18:39That's when ketchup comes in.
18:41Its key ingredient is tomatoes, and they have many nutrients similar to those you can find in oranges and some
18:49other citrus fruits.
18:51For instance, citric acid can help you remove rust from metal surfaces, since it eats through rust.
18:58We're not talking about the cars only.
19:00You can use it on metallic kitchenwares, furniture parts, jewelry, and rust spots on generally any metallic item.
19:09You can combine it with washing soda.
19:11It's not quite effective against rust, but when you combine it with ketchup, it'll do the work.
19:18Mix these two and apply them to the rusted area.
19:21Leave it like that for about half an hour, and wash it with a wet cloth or sponge.
19:28You can combine ketchup with salt instead, or just apply a lot of it on the rusty area, without using
19:35any additional ingredients.
19:38Ketchup removes tarnish from brass copper, too.
19:41Put it on brass hardware on doors and cabinets, or some accessories, such as bowls and candlesticks, for 10 minutes
19:49to make it all shine.
19:51And also, you don't put it on meat just because of taste.
19:55Ketchup breaks down its fibers, which means it makes it more tender.
20:00Locking handles as we know them were only invented relatively recently, in 1878.
20:06Before that, people had to get pretty inventive to secure their homes.
20:10Most folks used a latch string.
20:12They'd make a small hole in the door, thread a leather thong or string through it, and then loop it
20:17around a wooden bar.
20:18Even after doorknobs were invented, only the wealthy could afford a proper lock and key.
20:25Vacuum cleaners had a rough start, too.
20:27The first one was invented in 1901, but it was so huge that it wouldn't fit inside houses.
20:33Instead, vacuuming was offered as a mobile service.
20:36The machines were parked outside, and long hoses were fed through the windows.
20:41And to get to the client's house, these large cleaning machines were actually pulled by horses.
20:47Back in the day, animals even used to pull strollers.
20:51Yep, with kids inside.
20:53The stroller was first developed in 1733 for the daughters and sons of a British nobleman,
20:59who might have been a bit too lazy to walk with them every day.
21:02So, the first model was basically a shell-shaped basket on wheels that could be pulled by a goat or
21:09a small pony.
21:10This small chariot was cute, but probably not the safest way to get around.
21:16Refrigerators also used to be a bit scary.
21:19From the late 1800s until 1929, they used toxic gases like ammonia, methyl chloride, and sulfur dioxide to cool things
21:28down.
21:28People were so concerned about gas leaks that they began leaving their refrigerators in the backyard,
21:33instead of keeping them in the kitchen.
21:36This danger even inspired Albert Einstein to create a new model.
21:40In 1926, Einstein and his former student Leo Seelard invented a refrigerator with no moving parts,
21:47using safer, environmentally friendly gases to reduce the risk of toxic leaks.
21:52But it had one problem.
21:54Einstein's refrigerator was less efficient than existing appliances, so it wasn't commercially appealing.
22:01If you ever find yourself casually wandering in the forests of Estonia,
22:06don't freak out if you see some giant megaphones.
22:09These wooden, acoustic giants were set three hours away from the country's capital by interior architecture students.
22:16That's way cooler than the hamster roller coaster I once built for a science fair, I have to admit.
22:22More than half of Estonia is covered by woods, and they're pretty proud of this natural wealth.
22:28So it's not the first art project of this kind, and there was a winding, elevated pathway and a faceted
22:34woodland cabin.
22:35The idea of the megaphones is to crank up the natural sounds of a forest and also to serve as
22:42a rest spot for hikers.
22:44These wooden beauties are large enough to host several people.
22:48And hey, if you walk this far into the woodland, you'll be thankful for this.
22:53The students were given a task to invent some concepts of a forest library.
22:58They built the megaphones off-site and brought them to their permanent spots.
23:03They're set in such a way that sounds from three directions meet in the center
23:07and create a cool, natural surround sound effect.
23:10Thankfully, kitchen supplies, including our beloved grills, have come a long way.
23:16Back in the 1950s, a metalworker named George Stephen had a brilliant idea while trying to create the perfect steak.
23:23Frustrated with flare-ups and uneven cooking, he decided to cut an old ocean buoy in half.
23:29This allowed him to control the airflow better.
23:32And that's how the Weber Kettle Grill was born, changing backyard barbecues forever.
23:37Have you ever used a public bathroom in the summer in your shorts and sandals and got splashed?
23:44It happens to the best of us, so no worries.
23:47If only there was some solution to this problem.
23:49Perhaps a urinal with a small hole so no liquid goes where it shouldn't.
23:54Looks pretty yucky and painful to me.
23:57An assistant professor at the University of Waterloo, Zhao Penn and his colleagues came up with a way better solution
24:04for this sensitive issue.
24:07Their designs were inspired by physics and dogs.
24:10When a stream of liquid moves on a solid surface at a shallow angle, the splash is reduced.
24:16And the smaller the angle, the fewer splashes you'll see.
24:19You can even minimize them to a zero.
24:22And when dogs do their business, they lift their hind legs and do it on the vertical surface of a
24:27tree or a wall.
24:29I don't know if they actually care about it, but this does reduce the splash.
24:33Good job, Pluto.
24:34Talking about that, here's a fun challenge for your next family gathering.
24:38Ask everyone to fold a piece of paper in half, then in half again, and keep going for a total
24:44of seven folds.
24:45Spoiler alert, they probably won't succeed.
24:48That's because each fold makes the paper thicker and thicker.
24:52In fact, if you had a huge sheet of paper and folded it in half 50 times, it would end
24:58up being about 62 million miles thick,
25:01which is about two-thirds of the way from Earth to the Sun.
25:04So, yeah, it's impossible.
25:06The current record is held by a high school student named Brittany Gallivan,
25:10who managed to fold a single piece of paper in half 12 times.
25:14And it was a tissue paper.
25:16The USB symbol, looking like a trident, has always sparked multiple speculations about its origin.
25:24One popular idea is that it represents Neptune's trident and symbolizes power and adaptability.
25:30But there's also a little bit less exciting theory.
25:34A man who claimed to have designed the symbol in the 1980s stated that it was supposed to represent connectivity.
25:40The large circle symbolizes a computer, while the attached shapes, the circle, the triangle, and square, stand for different outputs.
25:49Look closely at a tram's overhead lines, and you'll see that its contact wires zigzag back and forth instead of
25:56going in a straight line.
25:57That's because all trams have pantographs attached to their roofs.
26:02The upper part of the pantograph is gradually worn down by the overhead wire and eventually needs to be replaced.
26:09To wear it down evenly, the wire is not installed strictly along the tram's path, but in zigzag patterns.
26:16As the tram moves, the pantograph slides along the wire, and it wears down evenly.
26:23Those cone-shaped water cooler cups?
26:26Their shape is intentionally designed to prevent users from setting the cups down.
26:31This allows employees to minimize the risk of spilling water on their desks around various electronic devices.
26:37Plus, less material is used to produce cone-shaped cups, which makes the process less wasteful and more cost-effective.
26:45It also kind of supports sustainability by encouraging people to drink their water quickly and dispose of their cups immediately
26:51after.
26:52You're probably wearing a YKK product right now.
26:55I mean, go check the zipper on your jeans.
26:58Yep, that's it!
26:59YKK stands for Yoshida Kogyo Kabushiki Kaisha,
27:03a Japanese company that makes roughly half of all the zippers in the world, producing over 7 billion zippers each
27:11year.
27:12Originally called hookless fasteners, they became known as zippers after a pair of rubber boots that could be fastened with
27:19a single zip became popular in 1923.
27:22The name stuck because of the high-pitched zip sound they make when used.
27:27Despite a popular myth, household batteries don't actually contain liquid,
27:31and if you accidentally cut them open, no toxic liquid will spill.
27:36Most of them are dry cell batteries, which are made of electrochemical cells.
27:40Those convert chemical energy into electrical energy.
27:44Larger batteries often house numerous small cells within them, too.
27:48Even Tesla vehicle batteries consist of multiple small cells.
27:52When combined, they easily provide the necessary voltage.
27:56Did you know that nail polish used to be a status symbol?
28:00In ancient Egypt, queens like Nefertiti and Cleopatra were famous for their red nails,
28:06while lower-ranking citizens were only allowed to wear pale shades.
28:12You'll probably agree that there's no better snack than a pack of chips.
28:16Some are flat, others have ridges.
28:18Is it just aesthetics?
28:20Not really.
28:21The main purpose of those lines on some kinds of chips is to help with the distribution of spices and
28:26seasonings.
28:27In other words, all those substances that make your chips taste like cheese are mostly stored inside the lines.
28:33Plus, the lines make chips crunchier.
28:37This item here was also popular in ancient Egypt.
28:41What looks like a weird bench was actually a weird type of pillow.
28:45Back then, headrests were made from materials like wood, ceramic, and stone.
28:51Unlike our comfy pillows today, those ancient ones were used to protect people's hairstyles.
28:56That way, their hairdos stayed neat, even though they had a very uncomfortable night.
29:01If you've left a pot on the stove and your food burned, once again, take ketchup.
29:07Its acids will ease all the scrubbing and help you with grease.
29:12Just leave it over the night and you'll be able to wash the pot more easily.
29:17Or, keep those small packages of ketchup we all end up having from fast food orders in the freezer.
29:23The ketchup won't be as hard as an ice cube as it freezes.
29:27So, it will be good for soothing insect bites or similar things.
29:31For eight centuries, forks were considered cursed and nearly forbidden in the West.
29:36The first models were used by the elite in the Middle East and the Byzantine Empire.
29:41And they made their way to the West in 1004, thanks to a noblewoman named Maria Aguirre Polina.
29:48People were pretty shocked by it, to say the least.
29:50So, when she passed away just two years later, everyone blamed the fork, thinking it was some kind of divine
29:57punishment.
29:57By the way, its name comes from the Latin word furca.
30:01Which means, pitchfork.
30:03Next on our list is Nike's iconic moonshoe.
30:07But I'm talking about the unique pattern of its sole.
30:10Back in the 1970s, Nike co-founder Bill Bowerman was making waffles for breakfast with his wife.
30:16When he had a sudden idea.
30:19To pour a plastic material called polyurethane into the waffle iron.
30:23The machine was ruined, of course.
30:25But I guess it was worth it, since that's how the first Nike waffle trainer was born.
30:29I mean, its sole.
30:31That clear fluid in gel pens is called the ink follower or stopper fluid.
30:36The gel in such pens contains pigment particles dissolved in a polymer solution.
30:41The main task of the stopper fluid is to be a barrier to prevent the gel from evaporating or leaking
30:46out.
30:48Without this transparent fluid, your gel pen wouldn't function.
30:52The fluid always stays in one position and doesn't get dissolved with the gel.
30:57Neither does it move backwards or flow out of the pen.
31:01Let's move on to another favorite snack.
31:03Popcorn.
31:04These days, cinema and popcorn go hand in hand.
31:07But it wasn't always this way.
31:09In the 1920s and 1930s, movie theater owners were hesitant to allow snacks in their theaters.
31:15They were worried about the mess and the crunching noises interfering with movies.
31:20Plus, popcorn used to cost only 5 to 10 cents, so they didn't see any financial benefit.
31:25But savvy street vendors saw a big chance.
31:28So, they got their own popcorn machines and started selling them outside theaters.
31:33That's why popcorn probably became the original clandestine movie snack.
31:38And theater staff would even have to check if people were hiding bags of it in their coats.
31:44Have you ever helped your friends move into a new apartment in a building without an elevator?
31:49Then you're gonna love this one.
31:52Houses in Amsterdam have hooks on top.
31:55This is a medieval invention for pulling stuff up the houses.
31:58The simple tech consisting of a wheel and a rope still functions now, centuries later.
32:03Why not just use the stairs?
32:05Well, if you get inside one of those narrow Amsterdam buildings, you'll see there's hardly enough room to comfortably ascend.
32:13And you can forget about even trying to pull a table on top.
32:17Back in the medieval ages, pretty much like now, only rich people could afford housing around the canals in the
32:23best parts of the city.
32:25Those people were mostly traders and used the canals for their business.
32:29They stored goods in the same houses they lived in.
32:33And with regular floods, they had to find a way to keep the goods dry.
32:37And that's why they needed to invent something to lift furniture, goods, boxes, instruments, and food on the upper floors
32:46and pull it in through fully open, wide windows.
32:49The lifting tech is one of the reasons the houses in Amsterdam are leaning forward.
32:55This position helped keep both the lifted stuff and the walls and windows safe during transportation.
33:01They didn't have to touch each other.
33:03The gables also assisted in the process and had to be made firm to withstand all the heavy weight.
33:10And in case you're wondering what gables are, they're sections of wall between the edges of a dual-pitched roof,
33:17typical for Amsterdam.
33:19Sticking with old-school fun, it's time to talk about cards.
33:23So, have you ever wondered how many times you need to riffle a deck to shuffle it completely?
33:28The answer is seven times, according to math.
33:31Even cooler, if you shuffle a deck right, you're probably creating a unique order that's never existed before and never
33:38will again.
33:40And if you have a deck at hand, check out the Four Kings.
33:43You'll notice that the King of Hearts is the only one without a mustache.
33:48He's not special or anything.
33:49I mean, he also used to have a mustache, but it was lost in the reproduction of the original design.
33:55Your home has more regular things that can do magic tricks.
33:58Like if you have a house or a big terrace and want to make a nice flower wall.
34:03Try old mattress springs.
34:05Just hang them on the wall and let your imagination run wild with flowers.
34:11An old flower sifter can still come in handy.
34:15For example, as a planter.
34:16Even if you don't have one, you might find it at a garage sale or a thrift store.
34:22Wallpaper is making its big comeback when it comes to home design.
34:26Maybe you can try something different and use some old books with torn pages.
34:31You just need to learn the basics of hanging wallpaper.
34:35And voila!
34:36You get a new cool place for your old books.
34:40There's a solution for the remains of an old book.
34:43Don't worry.
34:44You can have blocks where you'll keep your kitchen knives.
34:47It's pretty original, don't you think?
34:50Solitaire was probably everyone's go-to game to pass the time back in the 1990s.
34:55But its original purpose was far from it.
34:58When developers created this game, their idea was to teach people how to use a computer without them even realizing
35:05it.
35:06For example, dragging and dropping cards into one place helped people learn how to move files into folders.
35:12The same goes for Minesweeper, which was designed to help people get used to using a mouse and clicking.
35:20Cleaning blinds can be frustrating, but the next time you do it, try doing it with a sock over your
35:26hand.
35:27Hands are kind of perfectly shaped for getting all those nooks and crannies on the blinds.
35:32And the sock will do the rest.
35:36Here's something you wouldn't expect.
35:38Ice cubes can help you remove gum from carpet, clothing, and hair.
35:43Just put your clothes in the sink and add ice cubes.
35:47Leave it like that for a while.
35:49Ice will freeze the gum, so you can chip it away more easily.
35:53If the gum got stuck on the carpet, leave ice cubes right in the critical spot and remove the gum
35:59with a butter knife.
36:01It's a little bit harder to remove it from hair though, but still possible.
36:05Just wrap the ice and parts of your hair with the gum in a washcloth until the gum gets frozen.
36:11When you get there, you should be able to break apart the gum and free your hair using your fingers.
36:19Or, next time you have to deal with a splinter, just take one ice cube to numb that area before
36:25you even start doing anything.
36:27You might have noticed that movie theater seats are almost always red.
36:32This choice isn't random.
36:33It has strategic importance, which is rooted in visual science.
36:37The thing is, red light has a longer wavelength.
36:40It means that it's the first color to disappear in low light.
36:44It allows the audience to concentrate better on the screen once the movie begins.
36:48Such a design choice enhances the viewing experience by minimizing distractions.
36:54Speed bumps are crucial for pedestrian safety.
36:57But at the same time, they can seriously increase car emissions due to the non-stop acceleration and deceleration they
37:04cause.
37:06To address this issue, some cities, like London, are testing fake speed bumps.
37:10Those are optical illusions painted on the road.
37:13They look raised from a driver's perspective, but in reality, they're flat.
37:18Authorities hope that this approach will slow down drivers without having a negative impact on the environment.
37:26Soda bottles are always filled in such a way that there's some space between the liquid and the cap.
37:31That's because soda contains carbon dioxide.
37:34It's a gas that can expand once the bottle's heated.
37:37If there's no gap in the bottle, it can break because of the pressure building inside.
37:43Also, when you open your drink, the gases go out in the form of bubbles, making the drink overflow.
37:48The gap helps with this problem, too.
37:51If you're more into Angry Birds, Candy Crush, and other mobile games, that's totally normal.
37:57After all, more people have access to cell phones than to toilets these days.
38:01But not many of us stop to think about how disgusting our phones can be.
38:05The natural bacteria from our skin and the oils from our hands get transferred to our phones with every touch,
38:12swipe, and tap.
38:13This makes phones about 10 times dirtier than toilet seats.
38:17Yikes!
38:20Now, can you honestly tell me you have never used your phone while driving?
38:24I know, me too.
38:26But we both know that it can be dangerous.
38:29To help with this, some newer cars have a special feature called a heads-up display.
38:35This option shows important driving information in front of you, like speed and directions, so you don't have to look
38:42away from the road.
38:43It's like a floating screen on the road in front of you.
38:47This can help you drive safer and avoid getting a ticket for going too fast.
38:51Not all cars are so modern, so to drive safely, you need to put your phone away.
38:57Thankfully, some cars have special places for your phone while you're focused on the road.
39:02One specific 2021 model, Chrysler Pacifica, has a feature where the second row of seats can be folded down into
39:10the floor.
39:11It's good for carrying big items.
39:13But when the seats are up, these areas are good for storing things out of sight.
39:18Just remember to check and clean them out every once in a while, because they can become magnets for all
39:24sorts of knick-knacks,
39:25like french fries or wet swimsuits that will surely start to smell at one point.
39:30Keep some cleaning supplies in your car, just in case.
39:35Are you a science fiction fan?
39:37I have some good news for you then.
39:40Turns out that flying cars may be closer to us than we think.
39:43And it's not just because they look cool.
39:47Manufacturers are looking into developing such vehicles for practical reasons too.
39:51For starters, our standard roads are getting pretty congested as time goes by.
39:56We'll need some other means of transportation in the future to be able to cope with a large number of
40:02vehicles.
40:03You can find loads of flying car concepts online, for all preferences.
40:07There's one that looks like a giant drone, and another one like a mini-airplane.
40:12The simplest designs just took a car and put wings on it.
40:17Some cars will light up a snowflake on the dashboard every now and then.
40:21In case you're wondering, it's a sensor, and a pretty important one too.
40:26It shows the exterior ambient temperature.
40:29It gets activated when there's a road warning due to a sharp drop in temperature.
40:34It may sometimes even come with an audio warning or a message on your dashboard to inform you that the
40:40roads may be getting icy,
40:42so you can either adapt the speed or change to the appropriate tires if necessary.
40:49Cars these days aren't just adapted for the cold season.
40:53They come with cool features to help out during the summer months too.
40:57I'm talking about those neat sun visors.
41:00Check your car to see if it has this added bonus feature.
41:03We know they twist to help the driver out, even when they're not driving directly toward sunlight.
41:09Some visors can also extend, so they can provide shade to a larger area.
41:14If yours can't extend, there's a simple solution.
41:18Buy a sun visor extender.
41:20You can even find them online.
41:21They work by being attached to your existing sun visors or the windows for better shade coverage and visibility.
41:29Now, your car might have another hidden feature.
41:32Well, it's technically not in the car, but in its tires.
41:36These days, some cars come equipped with foam-filled tires.
41:40They were created to fix the problem of air-filled ones that often went flat.
41:45Why?
41:46Well, because foam-filled tires have many of the same benefits as air-filled tires without the danger of leaks.
41:53Regular air-filled tires can sometimes lose air over time, even if there hasn't been any damage.
41:59In most cars with this feature, the tires are not completely filled with either foam or air.
42:05They have a mix of both.
42:12A bonus of these modern tires is that they make the cars quieter.
42:16Generally, electric cars make less noise, but because of that foam, they end up being as quiet as a cat.
42:22Some people like the fact that they're quiet, while others prefer that classic screeching or rumbling that vehicles make.
42:30But even people who like the sound of regular engines might like the quietness of these new models because they
42:36are still very fast.
42:38Hey, I drive one, and it's fun!
42:43You might have stumbled upon a button called AEB.
42:46It stands for Automatic Emergency Braking, and it's a feature that uses sensors to detect if a collision is going
42:53to happen really soon.
42:54When activated, it will automatically apply the brakes to try and prevent something bad from happening or make it less
43:02severe.
43:02There are two types of AEB – one that only works at slow speeds, and one that works at all
43:09speeds.
43:10If the car can't be stopped completely, the AEB system will try to slow it down as much as possible
43:16to reduce the impact.
43:19Many cars now have systems that can warn you if someone is walking in front of you and can even
43:25automatically stop the vehicle to prevent an accident.
43:28These systems use special sensors that can also detect bicycles and animals.
43:33However, a study found that these systems don't always work well, especially at night.
43:38Even if your car comes equipped with this added feature, it's crucial to always pay attention while driving and not
43:46rely solely on these systems.
43:49A little thing called Lane Centering Assist helps you stay in the middle of your lane when you're driving on
43:55the highway.
43:56It's not a replacement for paying attention to the road either, but it can help guide you through gentle curves.
44:03You'll still be in control of the car and can turn the wheel if you want to go in a
44:07different direction.
44:08Some systems give you a lot of feedback, while others are more subtle.
44:13Lane Centering Assist can't handle sharp turns, and in most cars doesn't work if you don't have the cruise control
44:20on.
44:20What's also cool about this feature is that if it senses you've removed your hands from the wheel,
44:27it'll give you the warning to return to the correct driving position.
44:32A lot of accidents can happen when you're reversing your car, like out of the supermarket parking lot.
44:38Parking sensors can help prevent these things from happening by using radar or sound to detect things that the driver
44:45might not see from his position.
44:47These sensors will make a noise or show a warning on the car's screen to let the driver know something
44:53is there,
44:54like another car or a person passing by.
44:58If you're planning to have a road trip, you know how hard it is to adapt to various speed limits
45:04throughout the country.
45:05Traffic sign recognition is a technology that can help with that.
45:09It allows you to know what the speed limit is on the road you're driving on.
45:13It uses a camera to take pictures of traffic signs and display them on a screen in your car.
45:19This can be helpful if the signs are hard to see or if you miss them while driving.
45:24Some cars with this technology can even change their speed automatically based on the signs they see.
45:31This technology is mostly found in luxury cars, but it is becoming more common in other types of cars too.
45:39The AAA Foundation for Traffic Safety has made studies that show up to 6,000 drivers per year have bad
45:47accidents simply because they were too tired.
45:51Sure, I would like my car to come with built-in coffee makers or showers to keep me awake on
45:56those long days driving,
45:57but some do have systems that can tell when a driver is getting kind of snoozy.
46:02These systems monitor the movements you make while in the driver's seat.
46:06It looks at things like how you turn the steering wheel around and move the car.
46:11If it senses you're a bit too tired to move on, it'll make a noise and show a message on
46:16the dashboard urging you to take a break.
46:19Some of these systems even show a picture of a coffee cup to remind you to stop at the next
46:24gas station for a refreshing beverage.
46:27Might save your life too.
46:35Hey there, car owners.
46:36Gee, do I have an important message for you?
46:38You see, our cars are like our trusty sidekicks, always by our side, even in the most public places.
46:44But sometimes we come back to find unexpected surprises waiting for us.
46:48Try to imagine yourself strolling up to your four-wheeled companion, and there it is.
46:52A flyer, taunting you from under the wiper.
46:55Or, heaven forbid, a parking ticket just begging for your attention on the windshield.
47:00We've all been there, right?
47:01Well, hold on to your steering wheels because authorities have a brand new tip for you.
47:06And it's a real gem.
47:07If you see something on your car that doesn't belong, don't remove it with your bare hand.
47:13Intrigued?
47:14You see, police forces have been keeping a watchful eye on all things car-related, and they're not just about
47:19catching speedsters and enforcing traffic rules.
47:22They've got our backs when it comes to unveiling the latest tricks of the trade.
47:26Take Arlington, Virginia, for example.
47:28The authorities there recently noticed a spike in driver's side airbag thefts.
47:32To combat this madness, the police advised folks to park in well-lit areas, lock their vehicles, stash away their
47:39valuables, and why not throw in a steering wheel locking device for good measure?
47:43Some car thieves have also discovered a new superpower, using their smartphone cameras to peek into your car.
47:49It's like they have x-ray vision or something.
47:51These sneaky people can bypass the privacy tint in your car windows and get a clear view of your treasures,
47:57all without even taking a photo.
47:59Smartphones these days, huh?
48:01In response, authorities launched a stow-it-don't-show-it campaign, reminding everyone to remove their valuables from sight, or,
48:10at the very least, stash them away.
48:12But wait, there's more.
48:15Officers want us to be extra cautious about a new threat lurking around our vehicles.
48:19You know how it goes. Leaves, litter, and leaflets often find their way onto our beloved cars.
48:24Usually, we'd think nothing of it and simply give our vehicles a quick clean before zooming off.
48:29However, you should think twice before reaching out with your bare hands.
48:33Even if it's just to grab a seemingly innocent piece of trash.
48:36Why all the fuss, you might wonder?
48:39Well, let's take a peek at an incident that unfolded in Houston, Texas.
48:43Picture this.
48:44One woman, fresh from celebrating her birthday at a local restaurant.
48:49Heads back to her car, only to find a napkin sticking out of her car door handle.
48:53Now, at first, she didn't think much of it, and casually removed the napkin.
48:58Thinking it's just some random trash.
49:01But as it turns out, things then took a crazy turn.
49:03Not long after handling that suspiciously placed napkin, she started feeling some tingling in her fingertips.
49:09And before she knew it, her whole arm joins the tingle party.
49:12Leaving her feeling a bit numb.
49:14She got all lightheaded and even struggled to breathe.
49:17Being a responsible person, her husband dialed up 911 in a jiffy.
49:22Off she went to the hospital, racing against time to figure out what in the world caused this bizarre health
49:27rollercoaster.
49:28After a seemingly eternal six and a half hours, the doctors finally diagnosed her with acute poisoning from an unknown
49:34substance.
49:35They couldn't pinpoint the exact nature of the substance, because the woman only had a tiny amount in her system.
49:41But even that tiny amount was enough to make her feel like she just hopped on the wildest ride at
49:45the amusement park.
49:47Just imagine if she had wrapped that napkin around her entire hand.
49:50Yikes!
49:51One of her doctors suggested that this whole napkin incident might have been an attempted kidnapping targeting her car.
49:57Wait, what?
49:58A kidnapping involving a napkin and a car door?
50:01It's like a bad script for a low-budget comedy film.
50:04But here's where things get really intriguing.
50:07The local police department, in their noble quest to solve this mystery,
50:10revealed that they didn't receive any reports of similar incidents involving car doors and napkins.
50:15I guess that prankster genius didn't strike again.
50:18Or at least not yet.
50:20However, they do confirm that the woman's experience and symptoms align with other cases of poisoning.
50:26Of course, there are many other strategies to help keep both you and your car safe.
50:30Like when it comes to parking, it's all about that prime spot.
50:34Thankfully, specialists have some tips that will make your parking game strong and keep those pesky thieves at bay.
50:41First things first, if you're lucky enough to have a garage, park your precious vehicle in there at all times.
50:47But if you're out and about, it's advised that you find a well-lit and open area to park.
50:53You want your ride to be in the spotlight, not hiding in the shadows where mischief could be lurking.
50:58Now, here's a nifty little nugget of advice straight from the mouth of an ex-burglar.
51:03This guy knows the tricks of the trade.
51:06When you park, turn those wheels into the curb.
51:09I know it sounds weird, but trust me, it's worth it.
51:12By doing this, you're making life harder for those pesky intruders.
51:15They'll have to do some fancy maneuvering just to get away, and ain't nobody got time for that.
51:20And hey, here's an extra bonus tip for you.
51:22Try to find a car park that has reached the Parkmark standard.
51:26These parking locations have passed a police risk assessment, so you know they're legit.
51:30With these simple tips, you'll be parking like a pro in no time.
51:35These days, there's still a sneaky way thieves can get their hands on your ride, and it involves your beloved
51:39key.
51:40So, let's play it safe, shall we?
51:42First things first, keep those keys hidden away.
51:45When you're home, make sure they're out of sight and far from prying eyes.
51:49You wouldn't want any thieves playing fishing games with sticks and hooks through your letterbox, snatching your keys.
51:55Now, let's talk about keyless entry.
51:57You know, those fancy cars that unlock themselves with a wave of the key nearby?
52:01Well, if you have to push a button on your key to open your car, you don't have a keyless
