Apollo 13

Apollo 13 ★★★

I cannot stop thinking about the bit where tom hanks peed into space, like, I have so many questions. where does the pee go? does is disappear? does it freeze? does it just float around? where does it end up? does is come back to earth? if so, what happens then? can it get through the atmosphere? is it still a liquid? what if when it rains we're all being showered in tom hanks' piss?
