Nasa uploaded video on 20 January, showing British astronaut Tim Peake explaining how astronauts go to the toilet in space. Peake explained the process and showed the equipment used on camera.

"And of course the answer to the big question everybody asks: how do you go to the loo in space? It really is quite simple, here's the tube you pee in, take the cap off, turn on the fan, the air flow keeps everything going down the pipe and also for number 2, the air flow does the same thing"

Peake is spending six months in space as part of his Principia mission. The mission is Peake's opportunity to spend time on the ISS and run a range of experiments and test out multiple new technologies for future human exploration missions.
