This is a video of astronaut Samantha Cristoforetti demonstrating (without actually demonstrating) how to use the International Space Station's toilet. It works pretty much exactly how you'd expect, provided you didn't expect you could just use it like a regular toilet because you don't believe in low gravity. Also, astronauts must be super clean because Samantha doesn't seem to have any problem touching all the parts of the ONE TOILET that her and seven other people use everyday. Did you know the toilet actually bags your solid waste like picking up after a dog? Because it does that. Still, I spend a lot of time in the bathroom so I've got the feeling if I were ever an astronaut it would only be a matter of days before there was a mutiny and I was tossed out an airlock with my space-pants still around my ankles.
Keep going for the informative video, then go pee on your own floor.
Thanks to xAM, who agrees it's important to know these things in case you ever wake up and find yourself on a space station.
