Astronaut's YouTube video: How to use the loo in space
It's a question European Space Agency astronaut Tim Peake gets asked a lot -- how do you go to the "loo" in space? Peake took to YouTube to explain how it works.
"It really is plain simple, here's the tube you pee in, " Peake says while holding up a long grey tube with a yellow cap at the end. "Take the cap off, turn on the fan, the airflow keeps everything going down the pipe."
Peake then pats an space station toilet behind him, explaining that airflow works the same way for that as well.
Admit it -- you've been wondering. Check out Peake's video below for more details.
