We talking your standard Dyson Ball or Kirby or a space that is devoid of matter?
Outer space. You see, when it gets to about -10' it breaks up from the wind it catches from the force of gravity as it gains speed. I actually wondered if anyone on here ever did a thesis on the subject and could report back the fact that it would essentially be a continuous stream without any gaps due to the cohesion forces of the molecular structure of the liquid. It could essentially draw out the urine in an accelerated manner rendering one wounded or dehydrated or both. Just wondered is all, gheesh.
Schweickart: Well, actually, in Skylab we did something similar to that. But on Apollo the urine then would go outside, and you'd have to heat the nozzle because, of course, it instantly flashes into ice crystals. And, in fact, I told Stewart this, the most beautiful sight in orbit, or one of the most beautiful sights, is a urine dump at sunset, because as the stuff comes out and as it hits the exit nozzle it instantly flashes into ten million little ice crystals which go out almost in a hemisphere, because, you know, you're exiting into essentially a perfect vacuum, and so the stuff goes in every direction, and all radially out from the spacecraft at relatively high velocity. It's surprising, and it's an incredible stream of . . . just a spray of sparklers almost. It's really a spectacular sight. At any rate that's the urine system on Apollo.
