If a friend of yours has fallen through ice into a frozen body of water and you would like to save them, lie down on the ice and crawl out to them, DO NOT walk out to them standing up. This maximizes your surface area and lessens the likelihood that you will fall through the ice as well. – PhannyPaqued on Reddit

If you happen to someday find yourself on a sinking boat, and it goes underwater and you’re somehow able to get free, beware. Once the air neutralizes, if you’re far down enough, water pressure will kill you, and collapse your lungs.

To avoid this, scream all the way to the top. No joke. While you swim up, scream. It’ll keep the pressure from killing you. – _Fengo on Reddit

If you ever find yourself caught in a riptide, swim PARALLEL to the shoreline until you get out of the riptide. Swimming directly back to the shore while caught in one won’t get you anywhere and it’ll only exhaust you, making it extremely dangerous to do so. – TakeAHintDontRain on Reddit

I imagine pretty much any snack food that is starch based would work. Personally I find Doritos to work quite well.

So next time you’re lost in the woods, stop at the next vending machine you see and it might just save your life! – ATLL2112 on Reddit

If your hair on your arm or on your head is standing up on one end during a thunderstorm, lightning is about to strike you. If there is not a building or a car nearby, crouch down immediately. This forces lightning to find the next shortest distance possible it can strike, since lighting strikes the tallest thing in it’s area. – bbrocuber on Reddit
