There are only a few proud humans who can boast of pooping in space. But at the very least, we can now all visualize how they do it.

Has this ever happened to you? You're having a great fantasy about being an astronaut, but then you think about using the bathroom, and you just don't know how it works? Your lack of space toilet knowledge takes you right out of the fantasy and brings you back to dumb ol' Earth! What a waste of time.

Well, unless you were one of those lucky rich kids who went to Space Camp, you're not alone. (I assume that like, 40% of Space Camp was about learning about space toilets, right?) And thankfully, there's now this video from the European Space Agency and astronaut Samantha Cristoforetti to help you out. Cristoforetti explains the different suction systems for #1 and #2, plus how urine is recycled.
