We've all seen the movies: if you're ever thrown out into the vacuum of space, you can basically expect to disintegrate, right? Or your blood will boil, or something. Not true! Turns out, we're made of tougher stuff than Hollywood seems to think. For example, although many liquids do boil in open space, our blood is kept in check by our circulatory system and would therefore be OK. Freezing isn't a concern either, as a vacuum actually acts as a pretty good insulator. It's not all good news though: your death would still be pretty gruesome. The lack of air will render you unconscious in about 15 seconds... before you asphyxiate and die in about a minute.
