British astronaut Tim Peake may have a fairly packed schedule on the International Space Station -- he did his first space walk the other day, he hosts a regular music quiz, and there's the not-inconsiderable matter of the 265 experiments he has to complete before his return to Earth -- but that doesn't mean he hasn't got time to answer some of the public's more burning question, how to use a toilet in space?
In the video above, Peake cheerily demonstrates how astronauts go about their number ones and twos.
