The world is full of surprises. One moment you might be having a relaxing swim and the very next a rip current is dragging you away from the shore.

But that doesn't mean that we have to stop enjoying ourselves. Instead, we should focus on what we can control and prepare for all the curveballs.

And surprisingly, social media might be a good place to start. TikTok user Knowledgesaurus has been creating a video series that he calls "Facts that can save your life" where he explains how to escape dangerous situations or at least greatly improve your chances of staying safe.

Each of his uploads has received millions of views.

If you ever find yourself buried in rubble and can't get out, don't yell. You'll end up just wasting energy and losing your voice. What you should do is grab something and start tapping in intervals of three. Humans are great at noticing patterns and the rescuers will start to move towards that. Once you hear them, then you can start yelling.

If a tornado looks like it's not moving, that means it's heading towards you.

Or away from you, but better to assume that it is coming towards you!

A lot of backpacks have a hidden built-In whistle. The actual clip on many modern day backpacks that are meant for hiking or camping have that built-In whistle.

If you're ever at the beach and you see the water receding or far away from where it normally is, run. This normally means a tsunami is coming. And someone who paid attention in school in 2004 used this and saved their own life by getting out of there.

If you ever see square waves in the water, get out immediately. These waves have powerful currents under the water that can sweep you out and take you away.

Oh yes...or if the sand is being tumbled a lot, that's usually another sign.

If your car ever goes into water, open a window or door immediately. If you don't do this, the pressure differential is too great and it will keep everything shut and you have to wait until your car is completely filled with water in order to get out.

As an ice fisherman I've learned that if you choose to drive your car on ice, regardless of how thick it is, keep your seatbelt off and your windows down. That said, I don't care if the ice is 2 feet thick, I'm walking or snowmobiling, not driving a truck on it.

If you ever get caught in a rip current swim sideways, a rip current is a strong flow of water that moves directly away from the shore. And if you get caught in one and you try and swim straight in, it's just going to keep pushing you back and you're going to lose energy. So you need to swim sideways until you're out of it and then you can swim in.

And I read forward and see the riptide thing. Still, learn what they look like from the shore. Easy to see from above.

If you ever get lost or in an emergency situation, you have your cell phone, but you have no service. You can still call 911. Emergency calls will go through any connection, whether it's your carrier or not. And the same thing goes for any payphones. You don't have to pay. It's free to make a call to 911.

True only if there is at least one network with some signal. If you really are out in the wilds, with zero signal on any network, it is not going to work. Your phone should tell you whether you can do this - mine says "Emergency Calls Only".

If someone falls in cold water and is close to hypothermia, don't put them next to a fire. They need to be warmed up slowly. Otherwise it could be potentially fatal and they could experience something called afterdrop. And this is due to the fact that your blood flow cannot adapt quick enough to that change from extreme cold to extreme hot.

Also, keep them in a lying position. Sitting puts too much stress on the heart (unfortunately, this tidbit was discovered by Nazi experiments that killed the test subjects)

Rolling them in the snow immediately after they get out helps to remove excess water drying the clothing!

The explanation is bullsh*t. The problem about having them next to a fire is that the skin senses the warmth, so your brain wants to expand your blood vessels. The warmth is, at that point, only superficial though (skin is warm, muscles etc. below are still cold), so instead of absorbing heat from your extremities, your body will pump a lot of relatively warm core blood to your arms and legs, resulting in drastically sinking core body temp. Why do so many people - especially on tikfock - feel the need to explain stuff they don't understand themselves?

If you're in the wilderness with only a fire for heat, putting them close to the fire may be your only option to warm them. Your best bet in such a situation is to seek professional help, but if you're out in the wilderness with no help, pretty much anything you do is going to be sub-optimal, but will almost certainly be better than doing nothing.

And realize hypothermic bodies aren't able to warm up each other. Not enough body heat left.

there's an old story about some people off the coast of Scandinavia in a fishing boat that capsized. they got picked up within an hour by a cargo boat, and were fine when they got on the ship. they went downstairs to get hot coffee and died on the spot.

Oh no. That's awful. How sad. (The waters near Scandinavia would be bloody cold).

you get almost nakey, they get almost nakey, you snuggle up together and your body heat will warm them. (Better to have more almost nakey humans, so you can switch and/or have one human on each side) - nakey because wet clothes wil deplete more heat)

In movies, they put the person in a bathtub with warm water. Does it actually work?

Before natural disasters make sure to fill your tub up and your sink with water that is clean. According to the FDA, after major disasters, water's either cut off or heavily contaminated. So it's important to make sure you have enough supply of clean water.

It would be better to fill up containers rather than to have the water in contact with the air. Algae starts growing immediately in water, but the more you can slow it down enough so that it won't be dangerous to drink for several days.

If you're somewhere and you don't have the right size battery, you can use a smaller battery and put aluminum foil in that extra space and it will still work. The aluminum foil will transfer the electricity and get the job done.

This one is too short. You need the right voltage. AA and AAA are both 1,5V per cell, so it works, but this is no universal truth.

When you walk back to your car and you see something like a dollar bill or something on it, don't touch it. This is a common method for kidnapping where while you're going to grab that, they'll come up and grab you. So do not grab it, just drive. And the most common with this is T-shirts around a mirror or a dollar bill.

Urban legend. If someone is going to "grab you" that extra 2 seconds you take to grab something under a wiper or around a mirror is not going to make a difference.
