00:00Sometimes, when you type big text on your phone, it's pretty hard to get the cursor where it needs to
00:05be.
00:05You can control this little thing using your space bar.
00:08Simply hard-press the space bar and now you can move the cursor wherever it needs to go.
00:13Voila!
00:16You can get bite-sized pineapple pieces without using a knife.
00:19At least that's what this viral TikTok tip is promising.
00:23First of all, twist off the top of the pineapple, that part which has green leaves.
00:28It's pretty easy. Just grab it and make several twists.
00:32Then pick the pineapple up and pound it down on the kitchen table.
00:36Repeat the pounding for about five times to make sure you did it sufficiently.
00:41Now you're going to need some arm strength.
00:43Roll the pineapple back and forth while pressing down on it.
00:46The weight is supposed to help separate the core from the fruit.
00:50But beware if your pineapple is very ripe, it might start to release juice.
00:55Now, gently hold the pineapple skin, pull out one of its scales and enjoy your snack.
01:01If you've done everything right, you're supposed to be able to pull out a bite-sized piece that will separate
01:06from the core quickly.
01:09Here's another game-changing tip for your kitchen.
01:11Get a habit of storing the cling wrap in the freezer.
01:14When the wrap is cold, it's less sticky and much easier to unroll and use.
01:20You're welcome.
01:23We usually place these non-slit bathtub mats on the bathtub's surface to prevent falls.
01:28But when you're not using the bathroom, you can stick or hang them on the wall.
01:33This way, the mat will get dry way faster and you'll prevent the accumulation of soap and dirt leftovers on
01:39the bottom of the bathtub or shower.
01:42Gather your shower curtain into a single bundle and tie it into a big knot.
01:47This way, it won't create obstacles when trying to clean the bathtub.
01:53Remember those mysterious stripes on bathroom towels?
01:56It's not just a decoration.
01:58It's a stabilizer strip to help the towel last longer.
02:02Stripes help keep the towels fluffy by limiting the shrinkage every time you wash them.
02:07Therefore, the towel retains its shape, size, and flexibility over time.
02:13They're also handy when you need to dry and clean a narrow and hard-to-reach place where the thick
02:18part doesn't work because it's too fluffy.
02:21For example, the space between your toes or behind your ears.
02:26Also, the stripes help to sort towels by type.
02:30Otherwise, all the towels of the same color and texture would look alike.
02:34You can see the stripes when you fold the towels properly, so it's easier to differentiate.
02:39This way, you can keep all the towels together in a linen closet.
02:43Your family members will never confuse their own towels with someone else's.
02:49Are you sure you know how to use this flat paper box with matches?
02:53You just have to take a match and slide it across the striking surface, right?
02:58Turns out, there's another way.
03:00Put the matchstick head on the striking surface, close the box, and pinch it.
03:05Then, pull the match out with one quick and confident movement, and it should light up.
03:12By the way, when you light up a matchstick or a candle in a dark room, the flames don't have
03:17shadows.
03:18Did you know that?
03:21The circle on the plastic jug of milk can tell you if the milk is good or bad.
03:25So, when the circle is inside, take this as a good sign.
03:29And when it pops out, it means that the milk is expired.
03:34Also, the circle helps to keep the jug from blowing up if you drop it.
03:37When it hits the ground or any other surface, the ring will expand to keep the milk inside the plastic.
03:43And if you leave milk in the fridge for too long, it will develop gases.
03:47In this case, the circle will prevent the jug from popping inside the fridge.
03:52When it comes to plastic bags with frozen food, we usually cut off a strip from the top to open
03:58the package.
03:58But you don't have to throw the strip in the trash right away.
04:01You can tie the bag with the remaining food and put it back in the freezer.
04:07Let's say you're driving a car through the night.
04:09Suddenly, some annoying driver behind you with the brights on gets closer and spoils the party.
04:15You can flip this little tab on your rearview mirror and make the bright lights fade away.
04:19In fact, this little mirror that looks flat is a so-called prismatic wedge.
04:25What looks flat is an angled mirror with a wedge of glass.
04:29When you switch the mirror to dim mode, you change the angle of the mirror so it reflects more light.
04:36Here's a cool safety tip when you have to park your car at some risky spot at night.
04:40Pull out the driver's seatbelt, put it through the door handle, and fasten the belt as usual.
04:45This way, you'll ensure that nobody can get in during the night.
04:49Even if they succeed in getting the door unlocked, they still won't be able to come in.
04:55If your car got frozen on a cold winter night and the glass is covered with ice, you can clean
05:00it using the following tip.
05:02You don't need any special cleaning brush.
05:04Just fill a big, sealable plastic bag with hot water and wipe the bag over the car to defrost the
05:10ice.
05:11Now, wipe off the remaining water with a rag and you're ready to hit the road.
05:17Everyone knows how to hang a sweater, right?
05:20Well, there's a better way that helps avoid the shoulder pimples that arise when the hanger doesn't fit your clothes
05:25perfectly.
05:26Put your sweater flat on your bed and fold it in half, like this.
05:30Then, place the hanger on the sweater on a diagonal, like this.
05:34Remember that the hanger hook should be under the arm.
05:37Now, grab the arms and fold them across the hanger.
05:40And then, hold the body of the sweater and fold it across in the same manner.
05:46Congratulations! Now you know the perfect way to hang your sweater.
05:51If you're out of staples, you can just turn your stapler over and there's a secret little compartment where you
05:56can put a whole row of extra staples.
05:58And now you can just conveniently put it into your stapler and go on with your work.
06:05Now, there's a big chance that your oven door is removable.
06:09This way, you can clean it between the glass.
06:11Of course, the mechanism may differ depending on the model.
06:14So, first of all, check the lower corners of the door and you'll probably find two screws that will help
06:19you lift the door up and then put it back where it belongs.
06:24Here's a hilarious tip for peeling boiled chicken eggs.
06:28Remove some shells from the top of the egg, about the size of a small coin.
06:33Then, break up the bottom of the egg and now blow into the top hole as if you're blowing a
06:39balloon.
06:40The peeled egg should pop out of the bottom.
06:43Just make sure the eggs are hard-boiled.
06:47If you have a basic electric screwdriver, you can order special brush heads.
06:51Your cleaning routine will never be the same again.
06:55This device will help you quickly and easily clean the dirtiest tiles and gaps between them.
07:00Just spray some bath cleaner and let your screwdriver brush remove all the impurities.
07:05Although this simple tip is very satisfying, some say that the sound evokes memories of dentists and ultrasonic dental cleaning.
07:16What's hiding inside Coca-Cola cans and regular household batteries?
07:20Why do magnets affect breakfast cereals?
07:23Do crosswalk buttons actually work or are they just useless decorations?
07:29What does that USB symbol really mean?
07:33I'm not sure I know the answers to these and similar questions, but I'm eager to learn the truth together
07:39with you.
07:39Let's find it out.
07:41Coca-Cola cans have a secret few people know about.
07:45Here's a Coke can.
07:47Let's submerge it in a highly corrosive alkaline solution.
07:50The aluminum dissolves due to a process known as hydrolysis, and we can see a plastic liner inside the can.
07:57It's made from a polymer or epoxy resin, and serves as some kind of a protective barrier between the aluminum
08:04walls of the can and the rather acidic soda.
08:08Despite a popular myth, household batteries don't actually contain liquid, and if you accidentally cut them open, no toxic liquid
08:16will spill.
08:16Most of them are dry cell batteries, which are made of electrochemical cells.
08:21Those convert chemical energy into electrical energy.
08:25Larger batteries often house numerous small cells within them, too.
08:30Even Tesla vehicle batteries consist of multiple small cells.
08:33When combined, they easily provide the necessary voltage.
08:39Most toothbrushes have differently colored bristles, but they aren't just pleasing to the eye.
08:44Those bristles, often blue, have a functional purpose.
08:47They're called toothbrush indicators, and their colors fade as you use the brush.
08:52The American Dental Association recommends changing your toothbrush at least four times a year.
08:58And by getting paler, these bristles help you figure out when it's time to replace your toothbrush.
09:04You'll probably agree that there's no better snack than a pack of chips.
09:08Some are flat, others have ridges.
09:10Is it just aesthetics?
09:12Not really.
09:14The main purpose of those lines on some kinds of chips is to help with the distribution of spices and
09:19seasonings.
09:19In other words, all those substances that make your chips taste like cheese are mostly stored inside the lines.
09:26Plus, the lines make chips crunchier.
09:30Now, this one might be a surprise, but some breakfast cereals are magnetic.
09:34That's because they're often fortified with iron in the form of a fine powder.
09:39Due to the added iron, cereal flakes get attracted to magnets.
09:43All this may sound kind of alarming, but in reality, the iron content in the flakes is minimal and doesn't
09:49pose any threat to your health.
09:52That clear fluid in gel pens is called the ink follower or stopper fluid.
09:57The gel in such pens contains pigment particles dissolved in a polymer solution.
10:02The main task of the stopper fluid is to be a barrier to prevent the gel from evaporating or leaking
10:07out.
10:08Without this transparent fluid, your gel pen wouldn't function.
10:13The fluid always stays in one position and doesn't get dissolved with the gel.
10:17Neither does it move backwards or flow out of the pen.
10:22Many pedestrian crosswalk buttons, namely in New York, are placebo buttons.
10:27They do literally nothing when you press them.
10:30Originally, they were functional after being introduced in 1964, but today, most of them don't affect traffic lights,
10:37which are programmed based on the real needs of the traffic flow.
10:41Why do such buttons even exist, then?
10:43It's a simple psychological trick, providing you with an illusion of control.
10:49You might have noticed that movie theater seats are almost always red.
10:54This choice isn't random.
10:56It has strategic importance, which is rooted in visual science.
11:00The thing is, red light has a longer wavelength.
11:03It means that it's the first color to disappear in low light.
11:06It allows the audience to concentrate better on the screen once the movie begins.
11:10Such a design choice enhances the viewing experience by minimizing distractions.
11:16Speed bumps are crucial for pedestrian safety.
11:19But at the same time, they can seriously increase car emissions due to the non-stop acceleration and deceleration they
11:26cause.
11:28To address this issue, some cities, like London, are testing fake speed bumps.
11:32Those are optical illusions painted on the road.
11:35They look raised from a driver's perspective, but in reality, they're flat.
11:40Authorities hope that this approach will slow down drivers without having a negative impact on the environment.
11:48Soda bottles are always filled in such a way that there's some space between the liquid and the cap.
11:54That's because soda contains carbon dioxide.
11:56It's a gas that can expand once the bottle's heated.
11:59If there's no gap in the bottle, it can break because of the pressure building inside.
12:05Also, when you open your drink, the gases go out in the form of bubbles, making the drink overflow.
12:11The gap helps with this problem, too.
12:15The USB symbol, looking like a trident, has always sparked multiple speculations about its origin.
12:22One popular idea is that it represents Neptune's trident and symbolizes power and adaptability.
12:28But there's also a little bit less exciting theory.
12:32A man who claimed to have designed the symbol in the 1980s stated that it was supposed to represent connectivity.
12:38The large circle symbolizes a computer, while the attached shapes, the circle, the triangle, and square, stand for different outputs.
12:48The design of a tennis racket has a specific feature known as the throat.
12:53It's an open space below the head of the racket.
12:56This space isn't just for storing balls.
12:59It also improves the racket's aerodynamics by letting air pass through.
13:03It seriously reduces drag during swings.
13:07Speaking of tennis, tennis courts are usually built with a north-south orientation.
13:13It helps minimize the impact of the sun's position during the game, ensuring that neither player has the sun directly
13:19in their eyes.
13:21Look closely at a tram's overhead lines, and you'll see that its contact wires zigzag back and forth instead of
13:28going in a straight line.
13:29That's because all trams have pantographs attached to their roofs.
13:34The upper part of the pantograph is gradually worn down by the overhead wire and eventually needs to be replaced.
13:41To wear it down evenly, the wire is not installed strictly along the tram's path, but in zigzag patterns.
13:49As the tram moves, the pantograph slides along the wire, and it wears down evenly.
13:56Those cone-shaped water cooler cups?
13:59Their shape is intentionally designed to prevent users from setting the cups down.
14:03This allows employees to minimize the risk of spilling water on their desks around various electronic devices.
14:10Plus, less material is used to produce cone-shaped cups, which makes the process less wasteful and more cost-effective.
14:17It also kind of supports sustainability by encouraging people to drink their water quickly and dispose of their cups immediately
14:24after.
14:27Most suitcases have two zipper pulls, and it serves several purposes.
14:32First of all, if one zipper fails, the other can keep the suitcase closed.
14:37Even better, having two zippers allows you to have easier access to small sections of your suitcase without having to
14:44open it entirely.
14:46And finally, when you have two zippers, you can connect them with a padlock for increased security.
14:54Some plastic milk containers have dents on their sides.
14:57These dents serve several purposes.
15:00When milk spoils, it usually causes swelling and high-pressure buildup inside the container.
15:05That's when the dent pops out and doesn't let the jug blow up.
15:09Plus, if you decide to freeze the milk, it will expand like any other fluid.
15:14And then again, the indentation will pop out and prevent the container from breaking inside your freezer.
15:22If you ever had a problem figuring out why fake pockets exist, you need to hear this.
15:28The main reason is that if a clothing item has a specific cut or shape, pockets may spoil it.
15:34They can alter the item's shape either in the warehouse or already on the retail rack.
15:39The solution?
15:41Getting rid of the pockets in key areas.
15:43Plus, fake pockets are obviously cheaper, and they don't get stretched out.
15:50The thermos wasn't actually invented to keep your coffee warm.
15:54It was made by a Scottish scientist who wanted a safe place to keep his chemicals at a stable temperature.
16:00So, he took two bottles, put the smaller one inside the bigger bottle, and vacuumed out the air between them.
16:10Can you believe it?
16:11There are two different ways to drink juice from a juice box.
16:15The first way is the default one.
16:17And the second is to flip the straw over so that its shorter side sits at the bottom of the
16:23box.
16:23Using the first method, you may have difficulty getting the last sips of liquid because the straw can't reach all
16:29the corners properly.
16:31Some straws have their bottom corner sharper than the top.
16:34It's deliberately designed that way to pierce through the seal.
16:38That's why some people believe the right way to drink juice is the conventional one.
16:43Now, let's continue with straws.
16:45Do you know there's a correct way to use a straw while drinking from a can of soda?
16:50So, you're about to have some Coke.
16:52You pop the tab open, then you put a straw in the can.
16:55Now, you need to make a constant effort to keep the straw steady.
16:59See this hole in the top?
17:01Yeah!
17:01Turn the pop tab around and put your straw through the hole.
17:05It'll serve as a straw holder.
17:07No need to be annoyed by the tipping straw.
17:10So, what's the best way to eat a cupcake?
17:13Turn it into a sandwich.
17:14Step 1. Peel off the paper wrapped around the cupcake.
17:18Step 2. Carefully divide the cake into two parts.
17:22Step 3. Put the bottom side of the cupcake on top of the frosting.
17:26This is how you eat a cupcake like a pro.
17:30Okay, another quick word about cakes.
17:32People generally use kitchen knives to cut cakes into two parts.
17:36But you can use dental floss.
17:39Take a piece of floss and wrap it around the cake horizontally.
17:42Hold the ends tight with both hands and pull them in opposite directions.
17:46There you go! Now you have an evenly cut cake.
17:50Smooth, huh?
17:51You can use floss to cut through a cake vertically, too.
17:54This way, you'll reduce the chance of messing up the frosting.
17:58Do you use your fingers to dip your Oreos in milk?
18:01Try using a fork.
18:03Stick it between the wafers vertically and dip the cookie in milk.
18:07Well, you try it.
18:08I'm sticking with my fingers.
18:09Been doing it all my life.
18:11Hey, call me a rebel.
18:12You put your food in the microwave.
18:14The plate is hot and the upper part of the dish is steaming.
18:18You start eating.
18:19Oh no, not again.
18:21Your meal hasn't heated evenly.
18:23If you want your dish to be equally warm, arrange it in a donut shape and leave an empty spot
18:29in the center.
18:30The middle part of your dish takes longer to heat up.
18:33By the time the center warms up, the edges might be overheated.
18:37Sometimes, you need to microwave two bowls of food at the same time.
18:41In this case, you can try placing the second bowl on top of a cup.
18:45This will give you free space for the second bowl.
18:48Creative solutions for small microwaves.
18:51Now, better to secure the cup first, though.
18:54Cleaning the splashed food will take more time than using this method.
18:58To save space, you should roll your clothes instead of folding them when packing.
19:02They don't get creased when you roll them.
19:04Plus, they take less space this way.
19:07Okay, we might as well continue with another packing trick.
19:10After rolling your clothes, pack them in your suitcase vertically, not horizontally.
19:15Your clothes will fit better into the bag, and you'll have more room for other essential stuff.
19:22Drinking iced coffee is a great way to cool your body on a summer day.
19:26Sadly, the ice cubes start to dilute the coffee pretty soon, changing the taste of the drink.
19:31To avoid this, you can freeze some coffee into ice cubes beforehand.
19:36This way, your iced coffee won't get watered down.
19:39It turns out that taking a shower too often isn't good for your hair.
19:44Experts say you should wash your hair two to three times a week,
19:48because overwashing can result in extra oil in your hair.
19:53Do you know there's a correct way to fit salami on a toast properly?
19:57Yeah, there's a geometry problem.
19:59Toast bread is square, but salami is mostly round.
20:03You can, of course, do it in a traditional way, by putting two slices next to each other.
20:07But then the edges of your sandwich won't have any filling.
20:11All you need to do is to cut the slices in half.
20:14Next, you line the straight pieces with the sides of the toast.
20:18You get four slices covering the entire piece of bread.
20:22Most people peel bananas starting from the top.
20:25But this way, you squeeze the fruit.
20:28The best way to peel a banana is to start from the bottom.
20:31Hey, take a closer look at monkeys.
20:33Apparently, they figured this out a long time ago.
20:36Do you want to have more space in the closet where you store your cleaning supplies?
20:41Then this one is for you.
20:43You can hang spray bottles on a clothing rod.
20:46It's convenient.
20:47You can find those rods online or in stores.
20:50This way, you'll keep your cleaning sprays organized.
20:53Also, this method leaves more cupboard space for other cleaning supplies.
20:58There's a right way to hold a burger.
21:01Grab it with both hands.
21:02Now, place your little fingers at the bottom next to your thumb for extra support.
21:08You want to cross out miswritten words?
21:10You can draw a line on top of them.
21:12But in most cases, you can still read the words.
21:15Instead of scribbling some lines, just write a bunch of random letters on the top of the word you want
21:21to cross out.
21:22Problem solved.
21:24What is the best way to cut crusty bread?
21:27By turning the loaf upside down.
21:29The underside of the bread is usually softer than the top.
21:32But try not to squeeze the bread too much.
21:35The traditional way to drain pasta is to place the colander in the sink.
21:41After that, you drain the water and put your pasta back in the pan.
21:44But this method isn't the most effective.
21:47Sometimes, pasta gets into the holes of the colander.
21:50The second option is less difficult.
21:53Place the colander into the pot and, while holding them together, drain the water.
21:58This way, you don't have to move your pasta from the pot.
22:02This trick works best if your colander fits your pot.
22:05If you don't want to buy several colanders, you can still use this method.
22:09But you should be more careful during the draining process.
22:13Now, does your freezer ever spoil food?
22:16You put ready meals and groceries in the freezer.
22:18Two weeks later, you'll open it, only to find your food freezer burnt.
22:23There are two reasons for this.
22:25First, you stock your freezer with too much stuff.
22:28Overloading can block the vent.
22:30Then the air inside the freezer won't circulate properly.
22:34The second reason might be the wrong temperature.
22:37The recommended freezer temperature is 0 degrees Fahrenheit or a bit lower.
22:42Now, what's the best way to hold a steering wheel?
22:45Most people clutch it at 12 o'clock, 2 o'clock, and 10 o'clock.
22:49This is not very safe, even if you have three arms.
22:52For those of us with just two arms, the proper way to grab the wheel
22:56is to put one hand at 3 o'clock and the other at 9 o'clock.
23:00It means placing your hands where the joints are, in case you need to give way to airbags.
23:05Holding the wheel differently prevents them from fully inflating.
23:10Toblerone is a fancy chocolate bar.
23:12But did you know there's a correct technique to break off pieces of this chocolate?
23:17Mm-hmm.
23:17Just push the triangle you want to separate toward the rest of the bar.
23:21Who would have thought?
23:23Pringles are another hard-to-eat but delicious thing.
23:27While trying to dig a piece out of the can, don't shove your whole hand in there.
23:31Instead, use a sheet of paper.
23:33Fold it link-wise and slide it into the can.
23:36Then gently pull it out, together with Pringles.
23:39Now you have a tray of crispy goodness.
23:43The Queen's Guard all appear to have the same uniform,
23:46with a shared role of standing stoically for a long time.
23:50But if you look closely at their hats, there are five different types.
23:55The Grenadier has a white plume.
23:58The Coldstream has a red one.
24:00The Irish, a blue plume.
24:02The Welsh, green and white.
24:04And the Scots Guard has none.
24:07Their different divisions perform similar ceremonial duties at Buckingham Palace.
24:12But they have other actual roles as well, suited to their specialization.
24:17When peeling your boiled eggs, you can see a hidden layer under the shell.
24:22These two membranes, an inner and outer one, are made from the same stuff as your hair.
24:26Keratin.
24:27It protects the inside from bacteria and stops liquids from escaping.
24:32You use X in your texts, which represents a kiss.
24:36It's been used this way for a very long time.
24:38Its original purpose dates back to the Middle Ages,
24:41where it was a representation of a person's faith, honesty and sincerity.
24:46Those that would sign off with an X would kiss it after signing as a display of a sworn oath.
24:53The X's meaning later changed to represent the action of kissing.
24:57And the first document showing this was a letter dating back to 1763,
25:03written by a naturalist, Gilbert White, who sent it to his wife.
25:08William Shakespeare is a name familiar to everyone.
25:11However, we don't know whether this was the actual way his name was spelled.
25:15And neither did he.
25:17He signed 80 different variations of his name spelling on all his works.
25:22Historians haven't a clue which the correct spelling is.
25:25The version that we know of was only used on two of his plays.
25:31Different forms of alarm clocks were invented as far back as 348 BCE,
25:36with many versions throughout the world, all with complicated mechanics.
25:41Unaffordable to mostly everyone, they didn't catch on.
25:45Alternate methods to wake up in the morning started to be used in the 1800s.
25:49One process involving knocker-uppers was common in some countries.
25:55A person visited your house every morning to knock on your door four times.
26:00Inventor Antoine Rédier felt that he should be woken only when he felt it necessary.
26:05So, in 1847, he invented the first adjustable alarm clock.
26:11Tennis balls in Wimbledon must be kept at a perfect temperature to ensure they bounce at a consistent level.
26:18They're stored at 68 degrees Fahrenheit,
26:21so they're cold enough that the molecules inside the ball shrink, ensuring they bounce lower.
26:27Then, they're continuously swapped throughout a match as they expand by being hit too much, becoming too bouncy.
26:34Wimbledon goes through 50,000 tennis balls each year.
26:39You enjoy the smell of a freshly mowed lawn, as you associate it with the weekends and summer.
26:45But that smell is a sign of stress made by the grass.
26:49Grass evolved to emit various elements when being eaten by bugs.
26:53This signal attracts predator insects to remove them.
26:57But unfortunately for the grass, there's nothing large enough to deter a lawnmower.
27:02There is no oxygen inside your packet of chips.
27:06If there was, it would influence the combination of molecules forming inside, spoiling the chips faster.
27:13The packets are instead filled with nitrogen, which pushes oxygen out.
27:17And this extends the shelf life and quality of your chips.
27:22You're traveling by plane overnight and just can't get to sleep.
27:27And the first night in a hotel wasn't great, regardless of how comfy the bed was.
27:32This is because of a human evolutionary trait called the first night effect.
27:38When you sleep in a different place than your home,
27:40the left side of the brain responds to more sounds while you're asleep.
27:44It continues to analyze your surroundings without you realizing,
27:48acting as though it's on a night watch and keeping you alert for any potential dangers.
27:54Most animals have this trait, although it's a lot more subtle in humans.
27:58But it's still effective enough to make sure you get your peanuts.
28:03Before playing basketball with hoops, you would have instead been playing with peach baskets.
28:08When the game was invented in 1891, a peach basket was used, with the bottom of it cut off.
28:14But it only took 15 years for players to grow tired of constantly collecting the jammed balls
28:19and to remove the basket altogether.
28:22When you click your fingers, the snapping sound isn't from the physical click of finger and thumb.
28:28The noise actually comes from the finger hitting the palm.
28:33The instant film for the first Polaroid cameras didn't have their own coating after taking a photo.
28:38To develop it, you applied it yourself.
28:41Waiting for it to dry took a long time, so shaking it sped up the process.
28:46Then, from the 1970s, the film provided everything required for the photo to develop,
28:51making the popular craze of shaking Polaroids pointless.
28:56Shaking the photo can cause the ink to wave or blur before drying properly,
29:00so you shouldn't actually shake it like a Polaroid picture.
29:03And just wait patiently instead.
29:06Bug spray doesn't repel all bugs, especially the worst of them all, mosquitoes.
29:12It does cover the scent of carbon dioxide, which is what attracts mosquitoes.
29:16But the spray only protects you for a short distance.
29:21Mosquitoes can also track carbon dioxide over long distances.
29:25They will continue to stalk you until they find a gap in your invisible bug shield.
29:30A great alternative is lavender, which contains linalool.
29:34This fragrance completely overloads the mosquito's senses, making it unable to track you.
29:40The half-belt on the back of some jackets appear like a fashion accessory.
29:45It was initially designed that way for larger jackets,
29:48as they could also be used as a blanket to wrap around oneself.
29:51The belt's position helps hold the material together,
29:55so it's easier to walk with whilst keeping you warm.
29:59Ketchup wasn't originally intended to be your favorite condiment.
30:03In 1834, a physician, John Cook, sold ketchup as a cure for indigestion.
30:10It was an immediate hit, and today, 10 billion ounces are purchased annually in the USA,
30:16although not as the intended medicine.
30:20Thomas Edison made over 1,000 inventions,
30:23and one in particular, the lightbulb, is most famously linked to him.
30:27However, he didn't actually invent it.
30:30Warren Delarue, a British chemist,
30:33had solved this scientific challenge 40 years earlier.
30:36There were also 20 other inventors who made alternate versions before Edison did.
30:41But earlier varieties relied on cotton thread and only lasted up to 14 hours.
30:47Edison, in 1880, used a carbonized bamboo thread instead,
30:52and his worked up to 1,200 hours.
30:55It became the most commercially viable lightbulb,
30:58and today's ones are similarly shaped to Edison's original.
31:02The first treadmill was used in England in 1818.
31:07It was a large wooden cylinder with a handrail,
31:09although it wasn't used to keep fit.
31:12Convicted criminals would be forced to use these for up to 10 hours per day as a punishment.
31:18The energy output potential was realized,
31:21and soon it was built to work with water pumps and grain grinders.
31:25It was so effective that it was used in all prisons throughout the country.
31:29But in 1902, it was decided that it was too harsh and stopped.
31:34And now, this cruel punishment is mainly found in gyms.
31:39During the 1940s, there was a shortage of cocoa,
31:42and it was important to find a solution to this problem.
31:45A production company found a way by mixing only a small amount of cocoa with hazelnuts and milk,
31:51and the original Nutella was created.
31:54It started out as a loaf spread, like a stick of butter.
31:58It then transformed into a creamier version inside a jar in 1951.
32:02But it wasn't until 1964 that it was given its famous name.
32:08Your passport might be a dark shade of either green, blue, or red.
32:13The darker color not only makes them appear more official,
32:16but is intended so that through its journeys,
32:18the dirt that's collected is more easily hidden.
32:23Wasabi was first used back in the 8th century.
32:26It wasn't meant as a spicy condiment as it's served with sushi today.
32:31Initially, it was used for its antimicrobial properties
32:34that help avoid the harmful reactions to fish with sushi that's a bit too old.
32:38I haven't felt verylexiged.
