@Joernroeschen There's lots of vomit in space. 50% of astronauts experience "space sickness" or "space adaptation syndrome.

The surface tension keeps the vomit balls together in giant spinning orbs, until they hit something, at which point they will wrap around it like an amoeba.
@Joernroeschen Every person to launch carries emesis bags in their flight suits. It usually clears up in two to three days, but not for everyone.

NASA informally measures space sickness on the "Garn scale"

Senator Jake Garn got very, very sick in space.
@Joernroeschen The Garn scale "...represents the maximum level of space sickness that anyone can ever attain, and so the mark of being totally sick and totally incompetent is one Garn. Most guys will get maybe to a tenth Garn if that high."
