When I was a kid during the Apollo era, I saw a Saturday afternoon special where astronauts were being questioned by kids, and one of the last questions was "how do you go to the bathroom in space?" I loved the response. They laughed good-naturedly over it, but they answered the question in full detail... and I remember quite clearly, although it was maybe 50 years ago, those urine dumps were described in very similar terms, ice crystals and all: "one of the most beautiful sights I've ever seen", said one, and they all laughed.

now i watched it. it was fun
