Tim Peake: The question you've been busting to ask

How do you go to the toilet in space? What happens to the waste products? And what happens if you miss?

She's also worked at Mission Control in Munich so is well-placed to answer them - with a little help from video of Esa and Nasa astronauts themselves.
