The right stuff. Floating around.
"Sort of windy when you're sitting there."
Juno: He's talking about going to the bathroom in space, and the various "problems" associated with going.
So here's a transcript. Enjoy.
"When you go to the bathroom on Earth, you're relying on gravity pretty heavily. Imagine if you were halfway done and somebody shut off gravity, it'd be a mess. And you'd float off the toilet, so, so when we designed our space toilet, first it has to have a seatbelt on it, to hold you down. And then we decided to separate solids and liquids, cause they're easier to store that way. So we just have a tube that you pee into, and it has air pulled into the tube, so it's not a big deal. For the women, there's a cup that fits up against them, and for the guys it's just like a little funnel, you just pee into this tube, and it goes into a sewage tank. But, the solids that come out of your body, that's a harder problem to solve, and it's an important medical one. Cause on Earth, everything falls on the floor, but in space it's gonna float around. So, so it'll really make you sick, if you reingest something that came out of your body it will really make you sick, and we can't afford to get that sick. So we designed a toilet that instead of gravity pulling everything into the toilet, it has air flowing, air pulling down into the toilet. It's sort of windy when you're sittin' there, but it pulls everything out of your body. Everything that comes out of your body gets pulled down into the toilet by the air. And then in the storage tank, we just expose that to the vacuum of space, which basically just freeze-dries everything, so it kills all the bacteria, so that there's no smell. And that, then we just store it.
And then when you have a whole bunch of it stored, we put it in a little unmanned supply ship, and we undock it, and it burns up in the atmosphere. So the next time you see a beautiful shooting star going across the sky (
audience laughter), that's what it might be."
