VIDEO: British astronaut Tim Peake explains how to poop in space

Have you ever looked up at the stars and wondered: how do astronauts poop?

Well, you can sleep soundly now, as British astronaut Tim Peake has finally given us a definitive answer on the matter - and no, it doesn't involve space nappies. Rather than wasting water - which is a scarce resource on the International Space Station - astronauts rely on fans to suck their waste out. It's a bit like going on an aeroplane, just a little more terrifying. https://www.youtube.com/watch?v=Vg5-9PMrWBo
