00:00Walking on pool covers is just asking for trouble, seriously.
00:05They might look harmless, all shiny and tempting, but some models aren't built to handle our
00:10weight.
00:11Fall through and you're in a whole world of trouble.
00:14First, you'll likely struggle to find the hole again, and once trapped, good luck trying
00:19to escape!
00:21Those covers are designed to float, so they're going to cling to you.
00:25Trashing around only makes things worse, increasing your chances of getting tangled up.
00:31From pools to swamps, now the danger shifts to bubbles seemingly drifting your way.
00:37Watch out, because that's a sign that an alligator might be nearby.
00:41During mating season, male alligators put on quite the show to attract females, even
00:46to the point of roaming neighborhoods.
00:49It usually takes a few weeks for the male to win over the female, and if she thinks
00:52he's a suitable partner, they start swimming around each other.
00:56But the mating act itself is surprisingly private, as it happens underwater.
01:01All that can be seen of the actual mating are the bubbles that rise from the bottom
01:05of the swamp.
01:07The next underwater threat is much smaller, only about 14 inches long.
01:13Bloodworms might seem small, but they're like little dangerous mutants.
01:17During their life, which is normally about 5 years, they feed on the metal they find
01:21in the sediment at the bottom of the ocean.
01:24This metal actually fuses with their jaws, creating metal teeth.
01:29Yep, their super sharp teeth are made of 10% copper, the highest concentration found in
01:36any animal.
01:37When this bright red marine worm is ready to strike, it inverts its digestive system,
01:43including those metal teeth, and shoots its guts like a torpedo right at its target.
01:48Oh, and its venom contains 32 different types of toxins, paralyzing its prey completely.
01:56The next red threat on our list is a flyer, the hooded patoe.
02:01Despite its cute appearance, this bird packs a venomous punch.
02:05Its feathers contain a chemical called batruchotocin, also found in poisonous frogs and certain
02:11beetles.
02:12Basically, when this toxin gets into your system, it messes with the normal functioning
02:17of sodium channels in nerve cells.
02:21This disruption keeps these channels open longer, causing nerves to fire uncontrollably.
02:26That can lead to paralysis, breathing problems, or worse.
02:30So if you ever find yourself in their native land, New Guinea, stick to the chicken dinner
02:36and stay away from this bird.
02:39Another thing you should never eat is the pufferfish, especially a type that is highly
02:43famous in Japan, known as fugu.
02:47If you really want to try it, just know that only skilled and licensed chefs can prepare
02:51it.
02:52Fugu has to be handled very carefully, because certain parts of the fish contain a toxin
02:57called tetrodotoxin.
02:59To understand how dangerous this substance is, consider that around 55 people per year
03:05lose their lives after eating this fish.
03:09Hundreds more experience symptoms like dizziness and vomiting.
03:13If prepared correctly, and I emphasize if, this type of pufferfish can be enjoyed as
03:19sashimi or in hot pot dishes.
03:22But I wouldn't dare to try it.
03:25If you ever stumble upon a foaming watermelon, do yourself a favor, don't eat it.
03:31The foam coming from the cracks in the rind happens because it's grown in super hot weather.
03:37In the US, for example, this fruit comes mostly from Florida, Arizona, California, Delaware,
03:44and Texas.
03:45When watermelons grow in that heat, they start fermenting.
03:49Once this process begins inside a watermelon, it creates the perfect environment for toxic
03:54pathogens to flourish.
03:56Trust me, that's not the flavor you want to explore since it can make you sick.
04:01Plus, if the fermentation process builds up and you decide to cut the watermelon, be prepared
04:06for a fruit explosion.
04:09Get rid of stinky potatoes as soon as possible.
04:13When these spuds turn mushy, they start giving off a nasty gas called solanine.
04:19Inhaling enough of it can knock you out cold and even give you wild hallucinations and
04:25raging fever.
04:26Usually, potatoes in that stage have a green color.
04:30Although the green color that forms on the skin of a potato is actually chlorophyll,
04:34which isn't toxic at all, its presence indicates concentrations of solanine.
04:40This toxin is produced in the green parts of the potato, the leaves, the stem, and any
04:45green spots on the skin.
04:47This strange process occurs because it's the plant's defense mechanism against insects,
04:53diseases, predators, and apparently, humans too.
04:57To prevent any bad consequences, remember to store your potatoes in a cool, dark place
05:02and remove the skin before eating them.
05:05Next on our list is something that we all love, hot dogs.
05:10Besides their zero nutritional value and controversial ingredients, the shape of hot dogs is a perfect
05:16plug for airways.
05:18In fact, this is actually the leading cause of choking for kids under 14.
05:23As a grown-up, you're probably already pretty cautious, but it's still smart to skip those
05:29hot dog eating contests.
05:32Never pick cashews straight from the trees.
05:35In their natural state, those little guys contain an oily resin called urushiol.
05:40If you come into contact with it, you can end up with a rash that itches and looks like
05:45a bad case of poison ivy.
05:47Fortunately, those raw cashews you find in supermarkets aren't really raw, they've been
05:52roasted at high heat once or twice to make them safe to eat.
05:57Once cashews are clear of urushiol, they go through quality checks and then they're good
06:01to hit the shelves.
06:03One thing that is not safe to buy, though, is clothes labeled as stain-resistant.
06:09I know it seems like a great deal, but those words might actually mean the item is packed
06:13with some not-so-cool stuff that can mess with your body, like purr and polyfluoroalkyl
06:20substances.
06:21So, along with all the usual stuff like processing and dyes, these fabrics get an extra dose
06:27of chemicals that stick around even after you wear them.
06:31Yep, stain-resistant clothes might be poisonous and can cause you all sorts of issues, like
06:37rashes, headaches, and brain fog.
06:40And I don't need any more brain fog.
06:44We've all heard it a million times, but it's worth repeating.
06:48Don't stand too close to a moving train.
06:50But why?
06:51Well, when a train speeds by on the tracks, the air rushes past at different speeds on
06:56either side of you.
06:58According to something called Bernoulli's theorem, the air pressure between you and
07:03the train is lower than the pressure on the other side of you.
07:06This creates a kind of suction that can pull you towards the train, putting you at risk
07:11of getting hurt.
07:13So yeah, it's definitely best to stay away from the tracks.
07:18But if your travel plan involves hopping into the passenger seat of a car, don't rest your
07:23feet on the dashboard.
07:24I get it, we've all done it.
07:27But this chill habit is seriously risky.
07:30One of the most crucial reasons to avoid putting your feet on the dashboard is the danger it
07:34poses if the airbag deploys.
07:37You might be wearing your kneecaps as a sleep mask.
07:40Airbags are meant to deploy with some serious force in a crash.
07:44If your feet are up there, you're way more likely to get hurt when that airbag slams
07:48into you, possibly causing some serious injuries, like fractures or dislocations.
07:54Plus, this bad habit compromises the effectiveness of the seatbelt.
07:58With your feet in an elevated position, the seatbelt might not keep you securely in place.
08:05So you're on a road trip headed for a camping adventure.
08:08You're wandering through the forest looking for the perfect spot to pitch your tent.
08:12But hold up, is that an orange X painted on a tree?
08:16You might think that this is just a sign that the tree is getting axed, but it's actually
08:20something else entirely.
08:22The U.S. Forest Service uses that symbol to mark boundaries, usually indicating the edge
08:28of the government-owned land.
08:30So if you spot an orange X on a tree, your best move is to turn around and head back
08:35the way you came.
08:37That's it for today!
