If you find yourself going into a freefall inside a metal tube hurtling through the clouds at hundreds of kilometres per hour, and an oxygen mask drops down right in front of you - try not to panic.  Aeroplane crashes are highly survivable. And here's what you can do to increase your chances of survival, according to science.  

Underknown shows take you to the frontiers of science, tell the greatest underknown stories from history and make the most complex ideas and theories entertaining and accessible. Underknown takes you beyond the familiar to explore, question and marvel at the magnificent vagaries of life on Earth and the Universe and ponder our best hopes for our planet, our lives, our children and our future.

How to live through one of nature’s most powerful events.

You’re on a beach. Not a worry in the world. The sun bronzing your skin, sand trickling between your toes,

Where’d all the water go? Did you see it going out? Now what?

Nope. Quicksand—that is, sand that behaves as a liquid because it is saturated with water—can be a mucky nuisance, but it's basically impossible to die in the way that is depicted in movies. That's because quicksand is denser than the human body.

Picture this, you’re having a nice, relaxing walk on a private beach without a care in the world. All of a sudden, your foot drops into a  deep and murky puddle. You struggle to pull your leg out, but it just won’t budge.

Before you know it, you’re sinking rapidly, and half of your body is submerged in cold, wet quicksand. The more you struggle, the more you sink. Talk about a terrible way to end a vacation.
