00:00In many cities and forests, there are color markings on trees that look weird to an unknowing spectator.
00:06In fact, most such markings are used for two reasons.
00:10To make the trees to be cut or left alone stand out from the rest,
00:14and to make an own forest boundary line visible.
00:17There are no specific rules for the color or shape of markings,
00:21but the most universal ones for cutting are blue lines,
00:24and the markings for preserving trees are usually orange or yellow.
00:29Trees within city limits are usually marked for cutting with red, orange, or yellow lines or dots.
00:35If you see such a marking on a tree and you have a car parked nearby,
00:40best move it somewhere farther away so that the tree doesn't fall on it when it's cut down.
00:46Trees in a forest can be marked for preserving because they have good cavities for wildlife to make homes in,
00:51or there are nests on their branches.
00:54It's a frequent practice to leave the surrounding trees intact too,
00:57so that the birds and animals in that particular tree are not disturbed.
01:01Large and healthy seed and nut bearing trees are also marked for preserving
01:06because many animals and birds feed on their seeds and nuts.
01:10Unhealthy trees can be preserved too, surprisingly, if woodpeckers seem to like them.
01:16It means there are many bugs inside those trees that the birds use as food.
01:21Color markings on trees in a forest might also mean someone owns the forest up to a certain boundary and
01:27decided to show it.
01:29These markings can be made in any color and shape, but they always have two specific features you can't miss.
01:35One is that the markings go in a more or less straight line, which is logical because it's a boundary
01:41of a territory.
01:42And the second feature is that, according to the marking rules, the markings always have to be close to each
01:48other
01:48so that the next one is clearly visible from the one you're looking at in both directions.
01:53Some believe that yellow markings are left on female ginkgo trees growing around cities of the U.S.,
01:59but there's no hard evidence of that.
02:01Still, you can find a detailed map of such trees in New York or Washington, D.C., for example.
02:08Female ginkgos do deserve a map of their own, since they bear fruit that smell really, really awful.
02:15If you ever had a piece of butter gone rancid in your kitchen, you probably know that odor.
02:20The trees were brought to the U.S. in the 18th through 19th centuries,
02:25when a drive for experimentation and all things exotic was going strong.
02:30And since ginkgos are very sturdy trees and can withstand harsh conditions, they grew popular in the country.
02:36Many cities planted them for green decoration purposes, but unfortunately, lots of them turned out to be females.
02:44To avoid the trees bringing their unpleasant smell into the cities,
02:48they've been sprayed with a special solution that prevents them from fruiting.
02:52The solution is safe for both people and animals,
02:55so there's no need to worry about being in the vicinity while maintenance workers spray the trees.
03:00Color markings can be seen in the streets, too, not only on trees.
03:05If you walk around the town and see a red line on the pavement, for example,
03:09it means there's a power line or cable beneath you.
03:12These lines are marked red to stand out the most, because if they're damaged while digging,
03:17it can lead to a lot of trouble, maybe even more than with gas pipes.
03:23Orange lines mean essentially the same, only those signify there's a telecommunication or signal line or cable.
03:30These things don't carry power, so disrupting them is not as bad as damaging power cables,
03:35but it would still cause a lot of inconvenience to people around the block.
03:39For example, breaking a fiber-optic cable might shut down the internet in a large area until the damage is
03:46repaired.
03:47A yellow line means there's natural gas, oil, steam, petroleum, or some other conduit of flammable material underneath.
03:56Lines are usually drawn in such a way as to show the direction the pipe is laid down below,
04:01and the line itself is in its center.
04:03Yellow is as much a color of warning as red, which makes perfect sense.
04:08A broken gas pipe and a spark are a recipe for a huge disaster.
04:14Green lines signify there's a sewer or storm drain underground.
04:18Breaking a sewer facility can cost an excavation worker their entire career, and for a good reason.
04:24Imagine what kind of a mess it would result in.
04:26And apart from the sewer contents breaking free and creating chaos on the surface,
04:32damaging the pipeworks will almost certainly result in huge costs of repairs,
04:36and lots of inconvenience for hundreds of people living close by.
04:41Since water is blue, it makes sense for city markings signifying a source of drinking water to be blue too.
04:48Damaging such a source is not as bad as breaking a petroleum pipe or a power cable,
04:52but it still is a cause of trouble for people around.
04:56In big cities, though, it's more of a nuisance than something serious,
05:00because potable water is normally easily accessible.
05:03Breaking a water pipe or main brings more problems to the excavating or construction project itself.
05:09The water will flood the surroundings, making it a mess to deal with as quickly as possible.
05:15Purple markings also mean water, but not of a drinking kind.
05:19Lines of this color signify there's a source of irrigation, or reclaimed water, down below.
05:25Such water is taken from sandblasting or power washing,
05:28and is normally used for industrial or gardening purposes afterwards.
05:32It's not meant for drinking, but the results of breaking through a pipe carrying this water
05:37are pretty much the same as with potable water.
05:40The mess will be more than real.
05:42Pink markings on the ground are left by land surveyors.
05:46When there's a legal argument for property limits, for example,
05:49an independent surveyor will leave pink lines on the ground to mark the boundaries.
05:54These can also be left at proposed construction sites for the same reason.
05:59White lines, dots, and crosses mark out the territory for proposed excavation routes or limits.
06:05It means there will soon be digging done within those premises.
06:09White markings usually indicate the exact place the excavation should be done at.
06:13They're the first step before any actual work can be performed.
06:18Later, city maintenance workers will find out if there are any facilities beneath that spot that should be avoided.
06:24If there are none, or if there's no conflict between the digging and the underground facilities,
06:30more about that later, the excavation can begin.
06:33City markings can also be drawn not as lines, but as other shapes.
06:38For instance, you might see an H-shape on the ground.
06:41The two parallel lines signify the edges of the pipe or cable below,
06:46while the center line connecting them is there to make it easier to measure the width.
06:51There might also be the name of the company that laid down the pipe or cable next to the H
06:56-shape.
06:56A diamond shape is another frequent marking on the ground.
07:00It might or might not have two parallel lines marking the edges of the conduit below,
07:05while the diamond shape itself means the approximate size of the thing beneath your feet.
07:10Some markings look more like graffiti, with lots of cryptic symbols and letters.
07:15But these are usually abbreviations and signs for the city maintenance or construction workers.
07:20For example, you might see a white cross or square drawn on the ground to mark a proposed excavation site.
07:27The workers will often write a no, followed by an abbreviated name of the facility below.
07:33You might think it means no excavation should be done here, but it's the exact opposite.
07:38No means no conflict between the power lines, pipes, or whatever other facility is buried underneath
07:45and the proposed excavation plan.
07:48The abbreviations are also written in the color of the facility they designate.
07:52For instance, if there's no G written in yellow paint in a white square,
07:58it means the site can be excavated without fearing that a gas pipe below, hence the G, will be disturbed.
08:04And if there's a telecommunications cable underneath,
08:08the city services will often draw an orange no,
08:11and then an abbreviated name of the company that laid down the cable.
08:16Another way to say the same thing is to draw an abbreviated facility type and cross it out.
08:21A yellow G, sometimes in a circle, means a gas pipe below.
08:26And if it's crossed out, there should be no worries about excavating in this area.
08:31No gas pipes will be damaged.
08:34Have you ever sat in the bathroom, wondering why toilet paper has fancy patterns on them?
08:39Well, if you're in there long enough, I guess you would finally get around to that.
08:43Turns out, those prints actually serve a purpose.
08:47They use the prints to fluff up the paper a bit and make it more absorbent.
08:52The unique patterns help differentiate different companies' products on the market.
08:56Also, recycled toilet paper is a thing, but it's not as popular or well-sold in the US as it
09:03is in Europe and Latin America.
09:05And that's all I have to say about that.
09:08Ah, yes, one of the greatest mysteries of the snack world.
09:12Why do crackers have holes in them?
09:14Crackers start out as hydrated dough, which means that they have a lot of wet ingredients in them compared to
09:20dry ones like flour and salt.
09:22So, when hydrated dough bakes, it releases steam as they get heated through.
09:27It results in something called an open crumb.
09:31It's a texture that is full of small air pockets.
09:34If we need a perfectly crispy cracker, the dough needs to release the steam that's accumulated in there.
09:40And that's where the holes come in handy.
09:42And all that crisp is thanks to them.
09:45Now, this star, some old houses and barns have, isn't something we pay attention to.
09:51But it's very familiar.
09:53It's known as a barn star, regardless of where it's located.
09:57Put it on a castle, it's still a barn star.
10:00No one is sure where exactly it takes its roots and what it originally meant.
10:04But they became particularly common for people to use at the end of the 19th century.
10:10Apparently, people used to paint geometric figures on their barns, and each one would mean something.
10:16The star was believed to bring good luck.
10:18Some people also interpret it as signifying welcome.
10:22And they started to put it on houses.
10:25Other people just say that they look cool and only serve a decorative purpose.
10:32Now, I'm pretty sure you've noticed that electrical plugs have holes in their prongs.
10:37But what are they used for?
10:39Well, a century ago, when the first plugs were designed, they had prongs with indents.
10:44Those indents would align with bumps inside the sockets to secure them there, so that it won't fall out.
10:51Later, the indents were replaced with holes, and it was for the same purpose.
10:55Modern-day plugs don't need holes to be secured inside.
10:59They're secured with friction and pressure.
11:02Holes are still useful, though, but only during manufacturing.
11:05Some insert a rod through the holes to keep them steady while they wrap them in plastic.
11:10Other than that, holes have no use.
11:13And they are optional.
11:14So the manufacturers can decide if they have them or not.
11:19I was driving a couple of days ago, and noticed those trees that you paint white at the bottom?
11:24Turns out, it's a common thing to do.
11:27You see, the lower trunks of trees are painted white to help the process called sunscald.
11:33Sunscalding happens in the winter, and it's the process where extreme fluctuations in temperatures
11:38causes the bark of the tree to split.
11:41The layer of white paint serves as a long-lasting tree sunscreen.
11:46They also use this method of painting the tree trunks in orchards and tree farms.
11:50It's done to protect the young trees and give them the best possibility of surviving their first years.
11:56I've noticed that in older cartoons, quite a bunch of characters wear white gloves.
12:01I did some research and found out that back when animated movies were black and white,
12:07putting white gloves on characters was a way to make the hands stand out from the black bodies.
12:12Then animation evolved, but the gloves stayed as a Disney tradition.
12:16But there are other reasons, too.
12:19Human hands make animal characters more humanized and relatable.
12:22Also, those gloves are way easier to animate, which speeds up the process.
12:26Also, many cartoon characters have four fingers, and there are reasons for that as well.
12:33First, only drawing four fingers makes the work of animators easier.
12:37While human figures were portrayed more realistically,
12:40animals and other characters could be fine with four fingers,
12:43and the creators were taking advantage of that.
12:46Also, there's a visual reason.
12:49Walt Disney himself told once that if this famous mouse had five fingers,
12:53his hands would look like a bunch of bananas.
12:57Growing up and watching morning cartoons before school,
13:00I never really understood why some of the adult characters didn't show their faces.
13:05Turns out, I was halfway to knowing the reason.
13:08The adults weren't the main focus of the shows.
13:11They were just there doing their adult stuff,
13:13while the main characters, often young-age characters or animals,
13:18were doing all the fun stuff.
13:19But the adult characters were always there to keep an eye on the main characters
13:23and help them if they asked.
13:25From an animation standpoint,
13:27it was also cheaper, easier, and way less time-consuming
13:31for the animators back then not to do the faces.
13:34This way, they wouldn't have had to do the faces
13:37or synchronize the lips for every speaking segment the character might have had.
13:41They could also just reuse old animations
13:44or change as little as possible
13:46if the writers changed the script at the last minute.
13:48It was saving companies lots of time and money.
13:52Now, we've all seen a house with two chimneys,
13:55but do they have an actual purpose,
13:57or is it purely for the aesthetic?
14:00Turns out, they actually did have a purpose back in the day.
14:03In the older houses that are located in colder climates,
14:06it was fairly common to have one chimney with two or more separate flues,
14:10passages for conveying gases to the outdoors.
14:14Back in the day, houses weren't as airtight as these days,
14:17so they needed more heating sources to stay warm.
14:20People had fireplaces and several wood-burning stoves.
14:24Having several flues allowed residents to vent all those gases at once.
14:29Modern houses are built way more airtight and isolated,
14:32so they don't really need more than one heating source to stay warm and cozy,
14:37even in colder climates.
14:38So, the two chimneys serve more of an aesthetic purpose.
14:42Also, they're costly to remove, even if someone lives in an older house.
14:47Sometimes, car's steering wheels are grossly sticky, and here's why.
14:51Steering wheels are often covered with materials like vinyl or leather,
14:55and both of them are prone to collect surface residues like dust,
14:59food grease, oil, and sweat from your palms.
15:01Even if you don't feel like your hands are dirty when you touch the wheel,
15:05there's always something on them, and that material is happy to keep it.
15:10At some point, surface residue accumulates enough to give you that sticky feeling.
15:15You have two solutions.
15:16Either wear driving gloves, or just wipe the steering wheel once in a while,
15:20and you're golden.
15:21I don't know if you've ever noticed that, but some school buses have white roofs.
15:27Apparently, roofs are painted white to ensure that the inside is cool on hot days.
15:32The thing is that dark colors, especially black, absorb light and heat.
15:37That's why asphalt is especially hot on hot days,
15:40and that's why you feel hot in dark clothes in summer.
15:44A white color, on the other hand, reflects the light and the heat,
15:48and everything gets heated less fast.
15:51If you've traveled, you could have noticed that the same temperature feels different in different places.
15:5780 degrees Fahrenheit in Nevada is much more tolerable,
16:00but the same 80 degrees Fahrenheit is a whole different story in Alaska or Florida.
16:05And the key here is humidity.
16:08It's the amount of water that's contained in the air.
16:11Nevada is the state with the lowest humidity, 38%.
16:14And Alaska has a humidity of 77%.
16:18Here's how it works.
16:20One of the ways your body tries to cool down during hot weather is by sweating.
16:25As the sweat evaporates, it takes away the heat as well, and it leaves.
16:29In humid settings, the sweat evaporates less, staying on your body and just dripping down.
16:35So not only do you stay all wet, but the heat also stays, so you feel hotter.
16:51The 28-year-old patient shows up at the hospital with distressing symptoms.
16:57He explained to the doctors that he felt really bad chest discomfort and had been coughing badly for quite some
17:03time.
17:03The medical staff knew right away there was no time to waste, so he was scheduled for an x-ray.
17:08Weirdly, there was nothing unusual about the x-ray results.
17:13The patient just had a mass in his lungs that they needed to remove as soon as possible.
17:18Sure, it wasn't the best news for the man, but it was certainly nothing the doctors hadn't seen before.
17:23But that first opinion changed on the day of the surgery.
17:27Not only was the whole operation more difficult than they had initially expected,
17:31but the mass they removed from the patient had an unusual shape.
17:35When the probe was sent for further investigation, the doctors were puzzled.
17:40It was a small fir tree!
17:42The doctors that had participated in the operation thought that the man must have inhaled a seed,
17:48which settled inside the man's lungs.
17:51After the seed grew into a sapling, its little needles started to damage the tissue surrounding it,
17:56which resulted in chest discomfort and coughing.
17:59As the story gained more popularity, scientists weighed in on the mysterious story.
18:04And they weren't so quick to accept it, saying it was most likely made up.
18:09On one hand, most plants need a lot of sunlight to grow, which isn't available in a human lung.
18:15More so, if it were that simple, we'd all have things growing in our bodies.
18:20Small seeds aren't that hard to swallow or inhale, right?
18:25This wasn't the only story about plants growing in a human lung that baffled scientists.
18:30In 2010, a man from Massachusetts was hospitalized after his lung collapsed.
18:36Again, this didn't seem to take doctors by surprise, as unfortunate as it was,
18:41because the patient already had a history of respiratory issues.
18:45Nevertheless, they discovered a mass inside the man's lung and removed it immediately.
18:50What they found was equally as surprising as the fir tree, a small pea plant.
18:55Only this time, doctors suggested that the man probably had peas for dinner.
19:00But that one simply went the wrong way and didn't end up in his stomach as it should have.
19:06Once it reached his lungs, the small pea got comfortable and began sprouting leaves.
19:11The truth is a bit more complex in this case, but it does make it more plausible.
19:16Turns out that the piece that was removed from the man's lung was only about half an inch long,
19:22something that small doesn't qualify as a full-grown plant.
19:25But the seed was able to grow, though.
19:28That's because a pea seed can sprout even without light.
19:31It naturally does that underground.
19:33The seed doesn't need to have any light at this point because the tiny seed has enough energy stored inside
19:39to help it grow to the level of the soil, where it gets the sunlight it needs to continue.
19:46Because of their relationship with the sun, plants are called autotrophs,
19:50or organisms that use exposure to light to feed themselves.
19:55A lot of us think that plants get their daily menu from the soil we place them in,
19:59but that's not feeding them.
20:01Plants need sunlight, water, and the gases in the air to produce glucose,
20:06the substance they use for food.
20:09This whole process is called photosynthesis and is performed by all plants,
20:14algae, and even a bunch of microorganisms, like the purple sulfur bacteria.
20:20Now back to our unfortunate human patient.
20:23While it's true that the pea seed might have germinated since it had sufficient moisture in there to survive,
20:28it didn't grow into a full-sized plant.
20:30It would have needed sunlight for that so that photosynthesis could begin.
20:35That's not to say it wasn't damaging or dangerous.
20:38A lot of other emergency room doctors have similar stories too,
20:43like this one coming from some doctors in Essex,
20:46whose patient initially seemed to have lost her dentures.
20:49The woman was elderly and already had memory problems,
20:53and they initially didn't give this mistake much thought.
20:55That wasn't until the woman was later discovered to have some other problems with her lungs too.
21:02It didn't take them long to connect the dots and figure out that the woman's upper dentures weren't all lost.
21:08They were just inside her body.
21:10The woman had swallowed them but didn't realize and they got stuck at the bottom of her throat,
21:16also causing her respiratory problems.
21:19Not all such mishaps happened by accident.
21:21Another man in the UK wanted to offer his fiancée the engagement ring of her dreams,
21:26but it didn't fit his budget.
21:28So he came up with what he believed to be a clever plan.
21:32He went to the jewelry parlor and patiently waited for the jeweler to shift his focus from the ring for
21:37a split second.
21:38As soon as that happened, he swallowed the ring.
21:41The jeweler wasn't easily tricked and called the police.
21:45Once under the metal detectors, the man could only confess.
21:48The crafty romantic was escorted to a cell where he was expected to,
21:53um, pass the ring back to its rightful owner.
21:56It's not the only reason people were caught swallowing jewelry.
21:59A woman once came up to the emergency doctor complaining about stomach pains.
22:04There was nothing bizarre about her.
22:06On the contrary, she was a middle-aged woman, both fashionable and tidy.
22:11Her physical exam didn't reveal anything suspicious about her.
22:15But the x-ray they had to make sure did.
22:18As they were looking at the images, the doctors were perplexed.
22:22A whole lot of jewelry was stuck inside the woman's stomach and intestines.
22:26The medical staff obviously questioned her about how the objects got there,
22:30and her response was even more outrageous.
22:33She said she wanted to keep her jewelry safe from her husband,
22:37which she claimed had a bit of a habit of gifting her jewelry to other women.
22:42Nice guy!
22:44One other doctor remembered having a patient with a bottle cap stuck in his throat.
22:49The problem is, he didn't even notice he had a strange object stuck inside of him.
22:54It was simply discovered at a routine checkup.
22:57Fortunately, no surgery was needed to fish this one out.
23:00Doctors managed to get it out using a small medical net.
23:04They were curious how this man managed to get a bottle cap stuck in his throat and not even know
23:09it.
23:10His response was simple.
23:11He did remember drinking water some days prior, but he couldn't find the cap.
23:15He brushed the whole thing off and went on with his day.
23:19Other times, naughty things we do when we were young can come back to haunt us years later.
23:25A 30-year-old woman surely learned this lesson the hard way
23:28when she ended up in the emergency room with a stuffy nose.
23:33No medicine seemed to help, so she knew she had to get it examined by a professional.
23:38Once the doctors had a look, they realized she had some inflamed tissue up her nose
23:43and something that resembled a foreign object.
23:46It also looked like that object had been there for quite some time.
23:50They couldn't figure out what it was, so she was immediately taken to the operating room.
23:56What the surgeons removed was then taken to be further investigated,
23:59and it turned out to be some sort of material resembling paper.
24:04After they questioned her, the woman did remember having stuffed some paper in her nose when she was little,
24:10but was just as surprised as the doctors that the small piece had stayed there up her nose for over
24:1620 years.
24:18Some extractions of foreign objects are more complicated than others.
24:22A kid ended up at the emergency room after he stuffed his brother's plastic construction toy up his nose.
24:28As the doctors were trying to carefully remove it, the kid coughed,
24:32and the toy went down his throat and into his stomach.
