00:00Now, doctors recommend risking your life at least twice a day.
00:04I mean, brushing your teeth at least twice a day.
00:06But you see, the seemingly harmless toothpaste that peacefully chills on every American counter
00:12poses a life-threatening danger because of one not-so-harmless ingredient, sodium fluoride.
00:19Now, don't get me wrong, not every toothpaste out there contains it, but most of them still do.
00:24But don't rush to the bathroom to trash or two.
00:27If you swallow a tiny pea-sized glob, it isn't fatal.
00:31I'm talking about larger quantities.
00:33A toothpaste tube has only 0.15% fluoride.
00:37To send you running to the hills, you must consume around 8 tubes one by one.
00:42So, technically, toothpaste is totally safe.
00:46Let's go and look for more dangers at your place, shall we?
00:50Personally, I don't have this one.
00:52But if you happen to have a CFL light bulb, you gotta be extremely cautious with it.
00:56The thing is, many of those bulbs are made with mercury.
00:59If such a bulb breaks, you gotta start by turning off your ventilation system.
01:04Otherwise, the contamination will only get worse.
01:07Make sure everyone has left the room, then open a window to allow for fresh air circulation.
01:12Finally, clean the area where the bulb's shattered.
01:15Be careful to address both wet and dry surfaces and contact specialists.
01:20Mercury vapors are definitely the biggest concern when it comes to this element.
01:24Take, for instance, a case of 2008, where a 55-year-old guy in Oklahoma tried to extract gold from
01:31old electronics using liquid mercury.
01:33Unfortunately, he inhaled too much vapor and sadly passed away just 10 days later.
01:39The contamination was so severe that they had to completely gut his house.
01:45Now, you definitely don't want your favorite clothes to get ruined by moths.
01:49So, you might grab some mothballs to exterminate them.
01:52But watch out!
01:54Those mothballs can exterminate you, too.
01:57They usually contain chemicals like naphthalene or a paradichlorobenzene.
02:02When these get into the air, they turn into gas.
02:04That strong smell you associate with mothballs kicks in.
02:07Those fumes can actually irritate your eyes and lungs and may even cause headaches, dizziness, and nausea.
02:14Plus, there are concerns about these chemicals being the cause of major conditions that even modern medicine can cure.
02:21Naphthalene is especially risky because it can break down your red blood cells, leading to a condition called hemolytic anemia.
02:29So, try to swap those balls for good old lavender.
02:32Moths aren't big fans of it.
02:35Now, it's super important to keep an eye on the plant you bring into your home, because some can be
02:39surprisingly harmful.
02:41Take Diefenbachia, commonly known as dumb cane, for example.
02:45Rumor has it that its sap can cause your tongue to swell up so much that it can block your
02:50airway.
02:51But can it really?
02:53Yes and no.
02:54It's true that this plant contains poisonous, tiny needle-like crystals called rapides.
02:59But they require someone to actually chew on a leaf first before any fuss happens.
03:04Otherwise, you might just feel a brief burning sensation or observe some skin redness.
03:10In rare cases, you might see some swelling in the area that touched the plant.
03:14Generally, just a little nibble leads to mild discomfort.
03:18So, please, don't snack on your potted plants.
03:20This warning is more for the safety of your pets, especially cats.
03:25Now, if Diefenbachia stays in contact with the mouth for too long,
03:29it can cause some serious pain that might linger for days or even weeks.
03:33In those cases, a trip to the hospital might be necessary,
03:37especially if the throat gets affected, as that could impact breathing.
03:41But don't believe the hype that Diefenbachia is a lethal poison.
03:44That's just an urban legend.
03:46The bottom line? One must be really dumb to get poisoned by a dumb cane.
03:52Now, using a power washer can be more dangerous than you might think.
03:56The intense pressure can lead to serious injuries,
03:59and the high-speed spray can kick up debris that might cause even more harm.
04:03If you do get injured, infections can set in quickly.
04:07And without timely medical care, things can get really serious.
04:10Think severe complications, potential limb loss, or even worse.
04:14But honestly, it's not that scary.
04:17Just don't overdo it with pressure.
04:21Here's a friendly tip.
04:22Don't skip out on your weekly house cleaning, especially when it comes to the bathroom.
04:27The longer you put off cleaning it, the more risky it becomes.
04:30Bathrooms are notorious hotspots for bacteria, which makes regular cleaning essential.
04:35You definitely don't want those unwelcome guests like norovirus, E. coli, salmonella,
04:42or even Staphylococcus aureus hanging around, along with those molds and mildews.
04:47Just put things into perspective.
04:49An average toilet seat can host over 200,000 colony-forming bacteria.
04:54And here's another thing to keep in mind.
04:56If you're not careful while cleaning, you can accidentally create a dangerous situation.
05:01Mixing bleach and ammonia can release a toxic gas called thuramine.
05:06Those fumes can lead to some pretty nasty symptoms, from shortness of breath to fluid in your lungs.
05:12Guess what?
05:13If it happens, you will probably kick the bucket.
05:16And I'm not talking about the one you use for cleaning the floors in the bathroom.
05:22On a sweltering summer day, having air conditioning is definitely a blessing.
05:26But don't let that trick you into thinking there aren't risks involved.
05:30If your AC is on the older side, it can lead to various issues.
05:34For example, the ductwork and filters can trap harmful mold, bacteria, and allergens.
05:40If those aren't addressed, folks near home might end up dealing with coughing, wheezing, or a stuffy nose.
05:46Plus, an aging AC unit can pose a fire risk.
05:50Older components tend to generate more heat as they try to keep up.
05:54And if they're not replaced, you could end up with a potential fire hazard.
05:58Faulty wiring is another concern, as many wires are tucked away in hard-to-reach spots, making them tough to
06:04inspect.
06:05So, if you have an older AC, it's a smart move to have it cleaned properly
06:10and ensure that its parts and wiring are up-to-date to avoid any fire risks.
06:17Snuggling under a cozy electric blanket when the weather turns chilly sounds like a dream.
06:22But if electric blankets get too hot, they might lead to burns.
06:26This risk is particularly significant with older models that don't have an automatic shut-off feature.
06:32So, the best way to use such a blanket is to warm up your bed and then turn it off
06:37before you crawl in.
06:38There's also the concern of heat stroke, linked to the use of an electric blanket.
06:42Once, two people were discovered unresponsive in their beds beneath electric blankets.
06:47The first person's body temperature reached an alarming 106.2 degrees Fahrenheit, while the second person's temperature was 105.8
06:57degrees Fahrenheit.
06:58So, while these blankets offer comfort, it's crucial to use them wisely.
07:04Just a quick heads-up about windshield washer fluid.
07:07It contains methanol, which can really pack a punch.
07:10If ingested, it can cause everything from dizziness and headaches to severe poisoning.
07:16Make sure to store it safely and keep it in the original container.
07:19Never transfer it to unmarked bottles.
07:21It can easily be confused with water and other harmless liquids.
07:25And that's a big no-no.
07:27Methanol is super toxic.
07:29For a grown-up, 2 to 8 ounces can do the trick.
07:32You know what I mean.
07:33The windshield washer fluid you dump into your car usually has about 30 to 50% methanol in it.
07:39But the concentrated versions?
07:41They can pack a serious punch with 90 to 100% methanol.
07:46Just remember, these products need to be diluted with water before you use them.
07:51The last everyday thing on our list does seem to be a great buddy of ours, especially if located in
07:57the bathroom.
07:58But although air fresheners can give your home a pleasant scent,
08:01many of them release volatile organic compounds that can build up over time
08:06and may post serious health risks, including neurological issues and incurable conditions.
08:12I suggest, if you were to ask me, you play it safe and think about opting for natural alternatives
08:18or enhancing your home's ventilation instead.
08:21Got that? Good.
08:29Hey there, car owners.
08:30Gee, do I have an important message for you?
08:33You see, our cars are like our trusty sidekicks, always by our side, even in the most public places.
08:38But sometimes we come back to find unexpected surprises waiting for us.
08:42Try to imagine yourself strolling up to your four-wheeled companion, and there it is.
08:46A flyer, taunting you from under the wiper.
08:50Or, heaven forbid, a parking ticket just begging for your attention on the windshield.
08:54We've all been there, right?
08:56Well, hold on to your steering wheels because authorities have a brand new tip for you.
09:00And it's a real gem.
09:02If you see something on your car that doesn't belong, don't remove it with your bare hand.
09:07Intrigued?
09:08You see, police forces have been keeping a watchful eye on all things car-related.
09:13And they're not just about catching speedsters and enforcing traffic rules.
09:16They've got our backs when it comes to unveiling the latest tricks of the trade.
09:20Take Arlington, Virginia, for example.
09:22The authorities there recently noticed a spike in driver's side airbag thefts.
09:27To combat this madness, the police advised folks to park in well-lit areas,
09:31lock their vehicles, stash away their valuables,
09:34and why not throw in a steering wheel locking device for good measure?
09:37Some car thieves have also discovered a new superpower,
09:40using their smartphone cameras to peek into your car.
09:43It's like they have x-ray vision or something.
09:46These sneaky people can bypass the privacy tint in your car windows
09:49and get a clear view of your treasures,
09:51all without even taking a photo.
09:54Smartphones these days, huh?
09:56In response, authorities launched a stow it, don't show it campaign,
10:01reminding everyone to remove their valuables from sight.
10:04Or, at the very least, stash them away.
10:07But wait, there's more.
10:09Officers want us to be extra cautious about a new threat lurking around our vehicles.
10:13You know how it goes.
10:15Leaves, litter, and leaflets often find their way onto our beloved cars.
10:19Usually, we'd think nothing of it and simply give our vehicles a quick clean before zooming off.
10:23However, you should think twice before reaching out with your bare hands.
10:27Even if it's just to grab a seemingly innocent piece of trash.
10:31Why all the fuss, you might wonder?
10:33Well, let's take a peek at an incident that unfolded in Houston, Texas.
10:37Picture this.
10:38One woman, fresh from celebrating her birthday at a local restaurant,
10:43heads back to her car, only to find a napkin sticking out of her car door handle.
10:48Now, at first, she didn't think much of it, and casually removed the napkin,
10:52thinking it's just some random trash.
10:55But as it turns out, things then took a crazy turn.
10:58Not long after handling that suspiciously placed napkin,
11:01she started feeling some tingling in her fingertips.
11:03And before she knew it, her whole arm joins the tingle party,
11:07leaving her feeling a bit numb.
11:09She got all lightheaded and even struggled to breathe.
11:12Being a responsible person, her husband dialed up 911 in a jiffy.
11:16Off she went to the hospital, racing against time to figure out what in the world caused
11:20this bizarre health roller coaster.
11:22After a seemingly eternal six and a half hours,
11:25the doctors finally diagnosed her with acute poisoning from an unknown substance.
11:29They couldn't pinpoint the exact nature of the substance,
11:32because the woman only had a tiny amount in her system.
11:34But even that tiny amount was enough to make her feel like she just hopped on the wildest
11:39ride at the amusement park.
11:41Just imagine if she had wrapped that napkin around her entire hand.
11:44Yikes!
11:45One of her doctors suggested that this whole napkin incident might have been an attempted
11:49kidnapping targeting her car.
11:51Wait, what?
11:53A kidnapping involving a napkin and a car door?
11:55It's like a bad script for a low-budget comedy film.
11:58But here's where things get really intriguing.
12:00The local police department, in their noble quest to solve this mystery,
12:05revealed that they didn't receive any reports of similar incidents involving car doors and napkins.
12:10I guess that prankster genius didn't strike again.
12:12Or at least not yet.
12:14However, they do confirm that the woman's experience and symptoms align with other cases of poisoning.
12:20Of course, there are many other strategies to help keep both you and your car safe.
12:24Like when it comes to parking, it's all about that prime spot.
12:29Thankfully, specialists have some tips that will make your parking game strong
12:32and keep those pesky thieves at bay.
12:35First things first, if you're lucky enough to have a garage,
12:39park your precious vehicle in there at all times.
12:42But if you're out and about, it's advised that you find a well-lit and open area to park.
12:47You want your ride to be in the spotlight,
12:50not hiding in the shadows where mischief could be lurking.
12:53Now, here's a nifty little nugget of advice straight from the mouth of an ex-burglar.
12:58This guy knows the tricks of the trade.
13:00When you park, turn those wheels into the curb.
13:03I know it sounds weird, but trust me, it's worth it.
13:06By doing this, you're making life harder for those pesky intruders.
13:10They'll have to do some fancy maneuvering just to get away,
13:12and ain't nobody got time for that.
13:14And hey, here's an extra bonus tip for you.
13:16Try to find a car park that has reached the Parkmark standard.
13:20These parking locations have passed a police risk assessment,
13:23so you know they're legit.
13:25With these simple tips, you'll be parking like a pro in no time.
13:29These days, there's still a sneaky way thieves can get their hands on your ride,
13:32and it involves your beloved key.
13:34So, let's play it safe, shall we?
13:37First things first, keep those keys hidden away.
13:39When you're home, make sure they're out of sight and far from prying eyes.
13:43You wouldn't want any thieves playing fishing games with sticks and hooks
13:46through your letterbox, snatching your keys.
13:49Now, let's talk about keyless entry.
13:51You know, those fancy cars that unlock themselves with a wave of the key nearby?
13:56Well, if you have to push a button on your key to open your car,
13:59you don't have a keyless entry.
14:01No worries, though. We'll cover that, too.
14:04Picture this.
14:05You're going about your day, minding your own business,
14:08when suddenly a crafty thief comes along with a little device.
14:10This sneaky gadget tricks your car into thinking your key is right there,
14:15unlocking it faster than you can imagine.
14:17They can even start the engine and drive off into the sunset with your beloved vehicle.
14:21Believe it or not,
14:22these pesky thieves only need to be a few meters away from your car key to capture its signal.
14:28That means they can work their magic even if your key is chilling inside your home, safe and sound.
14:33Fear not, because there are a few tips to keep your keyless entry car as secure as a fortress.
14:38When you're at home, keep that precious key and its spare far, far away from your vehicle.
14:44Maybe put them in a screened pouch or a fancy-schmancy Faraday bag to block any signals from escaping.
14:51Think of it as giving your key a cozy little invisible shield to protect it from those sneaky signal-sniffing
14:55thieves.
14:57Here's another pro tip.
14:58If you ever decide to adopt a second-hand car into your loving car family,
15:03give those keys a little makeover.
15:05Reprogramming them will ensure that any old signals or sneaky surprises from the previous owner are wiped clean.
15:11To make sure your car is always safe, we also need to cover this not-so-fun subject.
15:17Illegal tow trucks.
15:18Those sneaky thieves think they can snatch your precious wheels right off the street.
15:22Here are some tips on how to stay one step ahead of these parking lot pirates.
15:26First things first, keep an eye out for any tow-away crew that seems a bit fishy.
15:31You know, the ones who aren't sporting any fancy logos on their truck or who forgot to put on their
15:36snazzy uniforms.
15:37If something feels off, don't hesitate to report them pronto.
15:41Now, I know what you're thinking, but what if I'm wrong and it turns out to be a false alarm?
15:46We all should be about good faith, and nobody should blame you for a moment if it turns out to
15:50be a false alarm.
15:52Better safe than sorry, right?
16:06Trains used to make people mad.
16:07During the Victorian era, there was this rumor that the swaying motion of train carriages made passengers, especially men, go
16:15a bit crazy, leading to some strange and dangerous behavior.
16:20The so-called railway madness was supposedly triggered by the noise of the train.
16:25To make things worse, carriages were locked for privacy reasons back then, so people found themselves stuck in tiny spaces
16:32with lunatics who could snap at any moment.
16:38If you see someone putting ketchup on some car, it doesn't mean you're witnessing them preparing a prank.
16:44It means they're just taking care of their car.
16:48Yup, it goes great with hamburgers and hot dogs, but it goes even better with cars, since it has ingredients
16:55that are good at removing rust.
16:57Rust occurs when the metal gets exposed to moisture, oxygen, and heat, and due to weather conditions, it's hard to
17:05avoid it.
17:06When you leave rust for a longer time and don't deal with it, it will continue to degrade the metal.
17:13So, you need to get rid of it before your car becomes physically useless.
17:18That's when ketchup comes in.
17:21Its key ingredient is tomatoes, and they have many nutrients similar to those you can find in oranges and some
17:28other citrus fruits.
17:30For instance, citric acid can help you remove rust from metal surfaces, since it eats through rust.
17:37We're not talking about the cars only.
17:40You can use it on metallic kitchen wares, furniture parts, jewelry, and rust spots on generally any metallic item.
17:48You can combine it with washing soda.
17:50It's not quite effective against rust, but when you combine it with ketchup, it'll do the work.
17:57Mix these two and apply them to the rusted area.
18:00Leave it like that for about half an hour, and wash it with a wet cloth or sponge.
18:07You can combine ketchup with salt instead, or just apply a lot of it on the rusty area, without using
18:14any additional ingredients.
18:17Ketchup removes tarnish from brass copper, too.
18:20Put it on brass hardware on doors and cabinets, or some accessories such as bowls and candlesticks, for 10 minutes
18:28to make it all shine.
18:30And also, you don't put it on meat just because of taste.
18:34Ketchup breaks down its fibers, which means it makes it more tender.
18:39Locking handles as we know them were only invented relatively recently, in 1878.
18:45Before that, people had to get pretty inventive to secure their homes.
18:49Most folks used a latch string.
18:51They'd make a small hole in the door, thread a leather thong or string through it, and then loop it
18:56around a wooden bar.
18:57Even after doorknobs were invented, only the wealthy could afford a proper lock and key.
19:04Vacuum cleaners had a rough start, too.
19:06The first one was invented in 1901, but it was so huge that it wouldn't fit inside houses.
19:12Instead, vacuuming was offered as a mobile service.
19:15The machines were parked outside, and long hoses were fed through the windows.
19:20And to get to the client's house, these large cleaning machines were actually pulled by horses.
19:27Back in the day, animals even used to pull strollers.
19:30Yep, with kids inside.
19:32The stroller was first developed in 1733 for the daughters and sons of a British nobleman,
19:38who might have been a bit too lazy to walk with them every day.
19:42So, the first model was basically a shell-shaped basket on wheels that could be pulled by a goat or
19:48a small pony.
19:49This small chariot was cute, but probably not the safest way to get around.
19:55Refrigerators also used to be a bit scary.
19:58From the late 1800s until 1929, they used toxic gases like ammonia, methyl chloride, and sulfur dioxide to cool things
20:07down.
20:07People were so concerned about gas leaks that they began leaving their refrigerators in the backyard instead of keeping them
20:14in the kitchen.
20:15This danger even inspired Albert Einstein to create a new model.
20:19In 1926, Einstein and his former student Leo Seelard invented a refrigerator with no moving parts,
20:26using safer, environmentally friendly gases to reduce the risk of toxic leaks.
20:31But it had one problem.
20:34Einstein's refrigerator was less efficient than existing appliances, so it wasn't commercially appealing.
20:40If you ever find yourself casually wandering in the forests of Estonia,
20:45don't freak out if you see some giant megaphones.
20:48These wooden, acoustic giants were set three hours away from the country's capital by interior architecture students.
20:56That's way cooler than the hamster roller coaster I once built for a science fair, I have to admit.
21:02More than half of Estonia is covered by woods, and they're pretty proud of this natural wealth.
21:07So it's not the first art project of this kind, and there was a winding, elevated pathway and a faceted
21:13woodland cabin.
21:14The idea of the megaphones is to crank up the natural sounds of a forest and also to serve as
21:21a rest spot for hikers.
21:23These wooden beauties are large enough to host several people.
21:27And hey, if you walk this far into the woodland, you'll be thankful for this.
21:32The students were given a task to invent some concepts of a forest library.
21:37They built the megaphones off-site and brought them to their permanent spots.
21:42They're set in such a way that sounds from three directions meet in the center and create a cool, natural
21:48surround sound effect.
21:50Thankfully, kitchen supplies, including our beloved grills, have come a long way.
21:55Back in the 1950s, a metalworker named George Stephen had a brilliant idea while trying to create the perfect steak.
22:02Frustrated with flare-ups and uneven cooking, he decided to cut an old ocean buoy in half.
22:08This allowed him to control the airflow better.
22:11And that's how the Weber Kettle Grill was born, changing backyard barbecues forever.
22:17Have you ever used a public bathroom in the summer in your shorts and sandals and got splashed?
22:23It happens to the best of us, so no worries.
22:26If only there was some solution to this problem.
22:29Perhaps a urinal with a small hole so no liquid goes where it shouldn't.
22:33Looks pretty yucky and painful to me.
22:36An assistant professor at the University of Waterloo,
22:40Zhao Penn and his colleagues came up with a way better solution for this sensitive issue.
22:46Their designs were inspired by physics and dogs.
22:50When a stream of liquid moves on a solid surface at a shallow angle, the splash is reduced.
22:55And the smaller the angle, the fewer splashes you'll see.
22:59You can even minimize them to a zero.
23:01And when dogs do their business, they lift their hind legs and do it on the vertical surface of a
23:06tree or a wall.
23:07I don't know if they actually care about it, but this does reduce the splash.
23:12Good job, Pluto.
23:14Talking about that.
23:15Here's a fun challenge for your next family gathering.
23:18Ask everyone to fold a piece of paper in half, then in half again, and keep going for a total
23:23of seven folds.
23:25Spoiler alert.
23:26They probably won't succeed.
23:27That's because each fold makes the paper thicker and thicker.
23:31In fact, if you had a huge sheet of paper and folded it in half 50 times, it would end
23:37up being about 62 million miles thick,
23:40which is about two-thirds of the way from Earth to the Sun.
23:43So, yeah, it's impossible.
23:45The current record is held by a high school student named Brittany Gallivan,
23:49who managed to fold a single piece of paper in half 12 times, and it was a tissue paper.
23:56The USB symbol, looking like a trident, has always sparked multiple speculations about its origin.
24:03One popular idea is that it represents Neptune's trident and symbolizes power and adaptability.
24:09But there's also a little bit less exciting theory.
24:13A man who claimed to have designed the symbol in the 1980s stated that it was supposed to represent connectivity.
24:19The large circle symbolizes a computer, while the attached shapes, the circle, the triangle, and square, stand for different outputs.
24:28Look closely at a tram's overhead lines, and you'll see that its contact wires zigzag back and forth instead of
24:35going in a straight line.
24:37That's because all trams have pantographs attached to their roofs.
24:41The upper part of the pantograph is gradually worn down by the overhead wire and eventually needs to be replaced.
24:48To wear it down evenly, the wire is not installed strictly along the tram's path, but in zigzag patterns.
24:56As the tram moves, the pantograph slides along the wire, and it wears down evenly.
25:03Those cone-shaped water cooler cups?
25:05Their shape is intentionally designed to prevent users from setting the cups down.
25:10This allows employees to minimize the risk of spilling water on their desks around various electronic devices.
25:17Plus, less material is used to produce cone-shaped cups, which makes the process less wasteful and more cost-effective.
25:24It also kind of supports sustainability by encouraging people to drink their water quickly and dispose of their cups immediately
25:31after.
25:31You're probably wearing a YKK product right now.
25:35I mean, go check the zipper on your jeans.
25:37Yep, that's it!
25:38YKK stands for Yoshida Kogyo Kabushiki Kaisha,
25:43a Japanese company that makes roughly half of all the zippers in the world,
25:47producing over 7 billion zippers each year.
25:51Originally called hookless fasteners, they became known as zippers
25:55after a pair of rubber boots that could be fastened with a single zip became popular in 1923.
26:01The name stuck because of the high-pitched zip sound they make when used.
26:06Despite a popular myth, household batteries don't actually contain liquid,
26:11and if you accidentally cut them open, no toxic liquid will spill.
26:15Most of them are dry cell batteries, which are made of electrochemical cells.
26:19Those convert chemical energy into electrical energy.
26:23Larger batteries often house numerous small cells within them, too.
26:28Even Tesla vehicle batteries consist of multiple small cells.
26:31When combined, they easily provide the necessary voltage.
26:35Did you know that nail polish used to be a status symbol?
26:39In ancient Egypt, queens like Nefertiti and Cleopatra were famous for their red nails,
26:45while lower-ranking citizens were only allowed to wear pale shades.
26:51You'll probably agree that there's no better snack than a pack of chips.
26:55Some are flat, others have ridges.
26:57Is it just aesthetics?
26:59Not really.
27:01The main purpose of those lines on some kinds of chips is to help with the distribution of spices and
27:06seasonings.
27:06In other words, all those substances that make your chips taste like cheese are mostly stored inside the lines.
27:12Plus, the lines make chips crunchier.
27:16This item here was also popular in ancient Egypt.
27:20What looks like a weird bench was actually a weird type of pillow.
27:25Back then, headrests were made from materials like wood, ceramic, and stone.
27:30Unlike our comfy pillows today, those ancient ones were used to protect people's hairstyles.
27:35That way, their hairdo stayed neat, even though they had a very uncomfortable night.
27:41If you've left a pot on the stove and your food burned, once again, take ketchup.
27:47Its acids will ease all the scrubbing and help you with grease.
27:51Just leave it over the night and you'll be able to wash the pot more easily.
27:56Or, keep those small packages of ketchup we all end up having from fast food orders in the freezer.
28:02Either, the ketchup won't be as hard as an ice cube as it freezes.
28:06So, it will be good for soothing insect bites or similar things.
28:10For eight centuries, forks were considered cursed and nearly forbidden in the West.
28:15The first models were used by the elite in the Middle East and the Byzantine Empire.
28:20And they made their way to the West in 1004, thanks to a noblewoman named Maria Aguirre-Polina.
28:27People were pretty shocked by it, to say the least.
28:29So, when she passed away just two years later, everyone blamed the fork, thinking it was some kind of divine
28:36punishment.
28:37By the way, its name comes from the Latin word forca, which means pitchfork.
28:43Next on our list is Nike's iconic moonshoe.
28:46But I'm talking about the unique pattern of its sole.
28:49Back in the 1970s, Nike co-founder Bill Bowerman was making waffles for breakfast with his wife when he had
28:56a sudden idea.
28:57To pour a plastic material called polyurethane into the waffle iron.
29:02The machine was ruined, of course, but I guess it was worth it, since that's how the first Nike waffle
29:08trainer was born.
29:09I mean, its soul.
29:10That clear fluid in gel pens is called the ink follower or stopper fluid.
29:15The gel in such pens contains pigment particles dissolved in a polymer solution.
29:20The main task of the stopper fluid is to be a barrier to prevent the gel from evaporating or leaking
29:26out.
29:27Without this transparent fluid, your gel pen wouldn't function.
29:31The fluid always stays in one position and doesn't get dissolved with the gel.
29:36Neither does it move backwards or flow out of the pen.
29:40Let's move on to another favorite snack.
29:43Popcorn.
29:43These days, cinema and popcorn go hand in hand, but it wasn't always this way.
29:48In the 1920s and 1930s, movie theater owners were hesitant to allow snacks in their theaters.
29:54They were worried about the mess and the crunching noises interfering with movies.
29:59Plus, popcorn used to cost only 5 to 10 cents, so they didn't see any financial benefit.
30:04But savvy street vendors saw a big chance.
30:08So, they got their own popcorn machines and started selling them outside theaters.
30:13That's why popcorn probably became the original clandestine movie snack.
30:17And theater staff would even have to check if people were hiding bags of it in their coats.
30:23Have you ever helped your friends move into a new apartment in a building without an elevator?
30:29Then you're gonna love this one.
30:31Houses in Amsterdam have hooks on top.
30:34This is a medieval invention for pulling stuff up the houses.
30:37The simple tech consisting of a wheel and a rope still functions now, centuries later.
30:42Why not just use the stairs?
30:45Well, if you get inside one of those narrow Amsterdam buildings,
30:49you'll see there's hardly enough room to comfortably ascend.
30:52And you can forget about even trying to pull a table on top.
30:56Back in the medieval ages, pretty much like now,
31:00only rich people could afford housing around the canals in the best parts of the city.
31:04Those people were mostly traders and used the canals for their business.
31:09They stored goods in the same houses they lived in.
31:12And with regular floods, they had to find a way to keep the goods dry.
31:16And that's why they needed to invent something to lift furniture,
31:20goods, boxes, instruments, and food on the upper floors
31:25and pull it in through fully open, wide windows.
31:29The lifting tech is one of the reasons the houses in Amsterdam are leaning forward.
31:34This position helped keep both the lifted stuff and the walls and windows safe during transportation.
31:40They didn't have to touch each other.
31:42The gables also assisted in the process and had to be made firm to withstand all the heavy weight.
31:49And in case you're wondering what gables are,
31:52they're sections of wall between the edges of a dual-pitched roof, typical for Amsterdam.
31:58Sticking with old-school fun, it's time to talk about cards.
32:02So, have you ever wondered how many times you need to riffle a deck to shuffle it completely?
32:07The answer is 7 times, according to math.
32:11Even cooler, if you shuffle a deck right,
32:13you're probably creating a unique order that's never existed before and never will again.
32:19And if you have a deck at hand, check out the Four Kings.
32:22You'll notice that the King of Hearts is the only one without a mustache.
32:27He's not special or anything.
32:28I mean, he also used to have a mustache, but it was lost in the reproduction of the original design.
32:33Your home has more regular things that can do magic tricks.
32:38Like, if you have a house or a big terrace and want to make a nice flower wall,
32:42try old mattress springs.
32:45Just hang them on the wall and let your imagination run wild with flowers.
32:51An old flower sifter can still come in handy, for example, as a planter.
32:56Even if you don't have one, you might find it at a garage sale or a thrift store.
33:02Wallpaper is making its big comeback when it comes to home design.
33:06Maybe you can try something different and use some old books with torn pages.
33:10You just need to learn the basics of hanging wallpaper.
33:14And voila!
33:15You get a new cool place for your old books.
33:19There's a solution for the remains of an old book.
33:22Don't worry.
33:23You can have blocks where you'll keep your kitchen knives.
33:26It's pretty original, don't you think?
33:29Solitaire was probably everyone's go-to game to pass the time back in the 1990s,
33:34but its original purpose was far from it.
33:37When developers created this game,
33:39their idea was to teach people how to use a computer without them even realizing it.
33:45For example, dragging and dropping cards into one place
33:48helped people learn how to move files into folders.
33:51The same goes for Minesweeper,
33:54which was designed to help people get used to using a mouse and clicking.
33:59Cleaning blinds can be frustrating,
34:01but the next time you do it,
34:03try doing it with a sock over your hand.
34:06Hands are kind of perfectly shaped for getting all those nooks and crannies on the blinds.
34:11And the sock will do the rest.
34:15Here's something you wouldn't expect.
34:17Ice cubes can help you remove gum from carpet, clothing, and hair.
34:22Just put your clothes in the sink and add ice cubes.
34:26Leave it like that for a while.
34:28Ice will freeze the gum, so you can chip it away more easily.
34:32If the gum got stuck on the carpet,
34:35leave ice cubes right in the critical spot and remove the gum with a butter knife.
34:40It's a little bit harder to remove it from hair though, but still possible.
34:45Just wrap the ice and parts of your hair with the gum in a washcloth until the gum gets frozen.
34:51When you get there, you should be able to break apart the gum and free your hair using your fingers.
34:58Or, next time you have to deal with a splinter,
35:01just take one ice cube to numb that area before you even start doing anything.
35:06You might have noticed that movie theater seats are almost always red.
35:11This choice isn't random.
35:13It has strategic importance, which is rooted in visual science.
35:17The thing is, red light has a longer wavelength.
35:20It means that it's the first color to disappear in low light.
35:23It allows the audience to concentrate better on the screen once the movie begins.
35:27Such a design choice enhances the viewing experience by minimizing distractions.
35:33Speed bumps are crucial for pedestrian safety.
35:36But at the same time, they can seriously increase car emissions
35:40due to the non-stop acceleration and deceleration they cause.
35:45To address this issue, some cities like London are testing fake speed bumps.
35:50Those are optical illusions painted on the road.
35:52They look raised from a driver's perspective, but in reality, they're flat.
35:57Authorities hope that this approach will slow down drivers without having a negative impact on the environment.
36:05Soda bottles are always filled in such a way that there's some space between the liquid and the cap.
36:11That's because soda contains carbon dioxide.
36:13It's a gas that can expand once the bottle's heated.
36:16If there's no gap in the bottle, it can break because of the pressure building inside.
36:22Also, when you open your drink, the gases go out in the form of bubbles, making the drink overflow.
36:28The gap helps with this problem, too.
36:30If you're more into Angry Birds, Candy Crush, and other mobile games, that's totally normal.
36:36After all, more people have access to cell phones than to toilets these days.
36:40But not many of us stop to think about how disgusting our phones can be.
36:44The natural bacteria from our skin and the oils from our hands get transferred to our phones with every touch,
36:51swipe, and tap.
36:52This makes phones about 10 times dirtier than toilet seats.
36:56Yikes!
36:58A label on your panties digging into your most sensitive spots is definitely not the best feeling.
37:04Sure, you can cut it off, but often that just leaves even sharper corners that can be more annoying.
37:10But what if you've been cutting those labels wrong this whole time?
37:13Check it out.
37:14On the left, the label is sewn into the seam, while on the right, it's just hanging on by a
37:20couple of threads.
37:21Just snip those threads, and voila!
37:24It's like the label was never even there.
37:26Plus, with this little hack, you can always pick panties in the store that are guaranteed to be comfy.
37:32If you've traveled to Europe recently, you may have noticed how nasty the bottle caps have become.
37:38Yeah, according to the law, they now have to scratch your nose.
37:42Oops, sorry, they have to be attached right to the bottle.
37:45If these bottles annoy you too, try this.
37:48Once you open the bottle, rotate the cap 90 degrees, and pull until one of the plastic connections breaks.
37:54And finally, turn the bottle until the cap touches your chin, not your nose, and drink.
38:01You've been using the colander in the wrong way all this time.
38:04This smart kitchen device has a hidden function.
38:07The traditional way of draining noodles involves dumping boiled noodles into a colander, right?
38:13But if your colander is about the same size as your pot, try this instead.
38:18Place the colander on top of the pot with the noodles, like a lid, and drain the water out.
38:24This method is faster and less messy, and it keeps your noodles in the pot where they belong.
38:31Toilet plungers and sink plungers are quite different, and the toilet version has a handy rubber flap called a flange
38:38that pops out from the cup.
38:40This flange fits snugly over toilet drains, giving you strong suction to tackle stubborn clogs.
38:47While a sink plunger won't help with toilet troubles, the toilet plunger can work on your sink or tub.
38:53Just make sure to keep that flap tucked inside the cup.
38:57And don't forget to give it a thorough clean with bleach before switching from toilet to sink use.
39:02You definitely don't want to mix things up.
39:05If you still work in an office, next time you print out something, make sure to check out this stapler
39:11built right into the printer.
39:13It can staple all the documents that fit in the slot at the same time.
39:17By the way, it's not something new.
39:19Such printers have been around since the 90s.
39:23Why buy a ruler and spend your hard-earned dollars if you can simply use a dollar bill to measure
39:29whatever you want?
39:30Only as long as this whatever is somewhere around 6 inches.
39:35A dollar bill is just about this size.
39:39Even though many people are sure that those tiny holes on the bottom left side of your iPhone are the
39:45speaker, they're actually a microphone.
39:47And speaking of iPhones, if you've got one of the latest models and your phone is out of juice but
39:52there's no socket to be found nearby, here's a nifty trick.
39:56Grab a double-ended charger cord and connect it to another iPhone 15.
40:02Boom! Your phone gets a little power boost.
40:05I bet you've noticed that the hook on a tape measure is a little loose.
40:09Well, that's intentional.
40:11The hook moves just enough to account for its own thickness, ensuring both inside and outside measurements are accurate.
40:18So, if you ever thought it was broken, nope, it's just doing its job.
40:22As for the hole at the end, it's replacing the tape on the edge of a nail to get measurements
40:27from odd spots.
40:29The pockets on new suits are sewn shut to keep the jacket's shape during transportation and display.
40:36Of course, you can unpick them to use the pockets, but you need to be careful with what you put
40:41there.
40:41Anything heavy can easily distort the suit's shape.
40:44The important thing, though, is to remember to cut the threads holding the back vents together for better movement and
40:51comfort.
40:51Oh, and remember to cut those tacky stitches that fasten your new coat's vent, that flap on the back.
40:59Now, that sink squeegee thing actually hides a big secret.
41:03It can store water.
41:05Many sink squeegees have tiny holes that allow water to stay inside.
41:10But why would we need that water?
41:12Oh, you can release it as you squeegee, which will help you rinse the sink as you clean it.
41:19Here's a travel tip that will help you understand U.S. highways.
41:23In the U.S., highways with even numbers run east-west, and those with odd numbers run north-south.
41:29If a highway number starts with an odd digit, it's a spur, which means it doesn't reconnect to the main
41:36highway.
41:36If it starts with an even digit, it's a loop around or through a city that eventually reconnects with the
41:42main highway.
41:44And finally, numbers divisible by 5 are major highways meant for cross-country travel.
41:51Your iPhone camera can also translate laundry symbols, identify plants, and even recognize some bird species.
42:00It's like having a mini-encyclopedia in your pocket.
42:03Another trick, when using the markup feature while editing your photos, you might want to highlight a part of a
42:10picture.
42:10Put a circle around the needed area and keep your finger pressed down at the end of the stroke.
42:16Voila!
42:17Instead of a misshapen circle, you get a perfect one.
42:20It also works for squares, triangles, and stars.
42:24Barilla, probably the most famous pasta in the world, has teamed up with Spotify to create playlists that match the
42:31cooking time for different pasta shapes.
42:34Just start the playlist when you drop the pasta into boiling water.
42:37And when the music stops, your pasta is ready.
42:42Toasters have crumb trays at the bottom that you can and should clean regularly.
42:47Just slide it out and dump the crumbs.
42:50It's an easy way to keep your toaster clean and working well.
42:54You can use Google Maps to share your location in real time.
42:58Just tap your account icon, select Location Sharing, and choose how long to share.
43:03Your friends can track your progress and be ready when you arrive.
43:07You can also save your parking location by clicking the blue dot.
43:12Do you know that the knobs on some ovens have calibration screws on the back?
43:17You can adjust them to get more accurate temperature control.
43:20It'll definitely help you avoid overcooking or undercooking your meals.
43:25In non-prepaid gas stations in the U.S., try pressing Enter before swiping your debit or credit card.
43:32It'll take you to the prepaid screen, and you can enter the amount you need manually.
43:38If you're drinking outside on a windy day, place some coins in an empty cup,
43:43and then put the cup you're drinking from inside the first one.
43:47The weight of the coins will help you keep your drink from getting blown over.
43:51Simple, but effective.
43:54Once you've peeled your potato, you might spot some tiny divots,
43:58known as eyes, that still have some skin on them.
44:01Many peelers come with a handy scoop designed to tackle these little guys.
44:05Just take the scoop, dig in, and pop them out.
44:08Easy peasy.
44:10Your favorite potato recipe will be totally eye-free in no time.
44:16A cell phone's camera can help you to figure out whether your remote is working.
44:20The camera is sensitive to infrared,
44:22so you just need to turn it on and point the remote at the camera while pressing the remote's buttons.
44:28You'll see the LED flashing in response.
44:31If you spot nothing, something is definitely wrong with the remote.
44:36Bonus fact here.
44:37White vinegar isn't just for cooking.
44:39It's also the real laundry hero.
44:42If you add it to your laundry, it'll take out all the bad smells from your clothes.
44:47The amount to add can be anywhere from a splash to a cup during the wash.
44:52And don't worry about the vinegar smell.
44:54It washes away completely, leaving your clothes fresh.
44:57It's also great for removing hard water buildup.
45:03Now, can you honestly tell me you have never used your phone while driving?
45:08I know, me too.
45:09But we both know that it can be dangerous.
45:13To help with this, some newer cars have a special feature called a heads-up display.
45:18This option shows important driving information in front of you, like speed and directions,
45:24so you don't have to look away from the road.
45:26It's like a floating screen on the road in front of you.
45:30This can help you drive safer and avoid getting a ticket for going too fast.
45:35Not all cars are so modern, so to drive safely, you need to put your phone away.
45:41Thankfully, some cars have special places for your phone while you're focused on the road.
45:45One specific 2021 model, Chrysler Pacifica, has a feature where the second row of seats can be folded down into
45:53the floor.
45:54It's good for carrying big items.
45:56But when the seats are up, these areas are good for storing things out of sight.
46:01Just remember to check and clean them out every once in a while,
46:05because they can become magnets for all sorts of knick-knacks,
46:09like french fries or wet swimsuits that will surely start to smell at one point.
46:13Keep some cleaning supplies in your car, just in case.
46:18Are you a science fiction fan?
46:20I have some good news for you then.
46:23Turns out that flying cars may be closer to us than we think.
46:27And it's not just because they look cool.
46:30Manufacturers are looking into developing such vehicles for practical reasons too.
46:34For starters, our standard rows are getting pretty congested as time goes by.
46:39We'll need some other means of transportation in the future to be able to cope with a large number of
46:45vehicles.
46:46You can find loads of flying car concepts online, for all preferences.
46:51There's one that looks like a giant drone, and another one like a mini airplane.
46:55The simplest designs just took a car and put wings on it.
47:00Some cars will light up a snowflake on the dashboard every now and then.
47:05In case you're wondering, it's a sensor, and a pretty important one too.
47:09It shows the exterior ambient temperature.
47:12It gets activated when there's a road warning due to a sharp drop in temperature.
47:17It may sometimes even come with an audio warning or a message on your dashboard to inform you that the
47:23roads may be getting icy,
47:25so you can either adapt the speed or change to the appropriate tires if necessary.
47:33Cars these days aren't just adapted for the cold season.
47:36They come with cool features to help out during the summer months too.
47:40I'm talking about those neat sun visors.
47:43Check your car to see if it has this added bonus feature.
47:46We know they twist to help the driver out, even when they're not driving directly toward sunlight.
47:52Some visors can also extend, so they can provide shade to a larger area.
47:57If yours can't extend, there's a simple solution.
48:01Buy a sun visor extender.
48:03You can even find them online.
48:05They work by being attached to your existing sun visors or the windows for better shade coverage and visibility.
48:12Now, your car might have another hidden feature.
48:15Well, it's technically not in the car, but in its tires.
48:20These days, some cars come equipped with foam-filled tires.
48:24They were created to fix the problem of air-filled ones that often went flat.
48:28Why?
48:29Well, because foam-filled tires have many of the same benefits as air-filled tires without the danger of leaks.
48:36Regular air-filled tires can sometimes lose air over time, even if there hasn't been any damage.
48:43In most cars with this feature, the tires are not completely filled with either foam or air.
48:49They have a mix of both.
48:55A bonus of these modern tires is that they make the cars quieter.
48:59Generally, electric cars make less noise, but because of that foam, they end up being as quiet as a cat.
49:06Some people like the fact that they're quiet, while others prefer that classic screeching or rumbling that vehicles make.
49:13But even people who like the sound of regular engines might like the quietness of these new models because they
49:20are still very fast.
49:22Hey, I drive one, and it's fun!
49:26You might have stumbled upon a button called AEB.
49:29It stands for Automatic Emergency Braking, and it's a feature that uses sensors to detect if a collision is going
49:36to happen really soon.
49:38When activated, it will automatically apply the brakes to try and prevent something bad from happening or make it less
49:45severe.
49:45There are two types of AEB – one that only works at slow speeds, and one that works at all
49:52speeds.
49:53If the car can't be stopped completely, the AEB system will try to slow it down as much as possible
49:59to reduce the impact.
50:02Many cars now have systems that can warn you if someone is walking in front of you and can even
50:08automatically stop the vehicle to prevent an accident.
50:12These systems use special sensors that can also detect bicycles and animals.
50:17However, a study found that these systems don't always work well, especially at night.
50:22Even if your car comes equipped with this added feature, it's crucial to always pay attention while driving and not
50:29rely solely on these systems.
50:32A little thing called Lane Centering Assist helps you stay in the middle of your lane when you're driving on
50:38the highway.
50:39It's not a replacement for paying attention to the road either, but it can help guide you through gentle curves.
50:46You'll still be in control of the car and can turn the wheel if you want to go in a
50:50different direction.
50:52Some systems give you a lot of feedback, while others are more subtle.
50:56Lane Centering Assist can't handle sharp turns, and in most cars doesn't work if you don't have the cruise control
51:03on.
51:04What's also cool about this feature is that if it senses you've removed your hands from the wheel,
51:10it'll give you the warning to return to the correct driving position.
51:15A lot of accidents can happen when you're reversing your car, like out of the supermarket parking lot.
51:21Parking sensors can help prevent these things from happening by using radar or sound to detect things that the driver
51:29might not see from his position.
51:31These sensors will make a noise or show a warning on the car's screen to let the driver know something
51:37is there,
51:37like another car or a person passing by.
51:42If you're planning to have a road trip, you know how hard it is to adapt to various speed limits
51:47throughout the country.
51:48Traffic sign recognition is a technology that can help with that.
51:52It allows you to know what the speed limit is on the road you're driving on.
51:57It uses a camera to take pictures of traffic signs and display them on a screen in your car.
52:02This can be helpful if the signs are hard to see or if you miss them while driving.
52:07Some cars with this technology can even change their speed automatically based on the signs they see.
52:14This technology is mostly found in luxury cars, but it is becoming more common in other types of cars too.
52:22The AAA Foundation for Traffic Safety has made studies that show up to 6,000 drivers per year have bad
52:30accidents simply because they were too tired.
52:34Sure, I would like my car to come with built-in coffee makers or showers to keep me awake on
52:39those long days driving,
52:40but some do have systems that can tell when a driver is getting kind of snoozy.
52:45These systems monitor the movements you make while in the driver's seat.
52:49It looks at things like how you turn the steering wheel around and move the car.
52:54If it senses you're a bit too tired to move on, it'll make a noise and show a message on
52:59the dashboard urging you to take a break.
53:02Some of these systems even show a picture of a coffee cup to remind you to stop at the next
53:07gas station for a refreshing beverage.
53:10Might save your life too.
