Sep 16, 2012 at 13:35 comment added Craig Feinstein I always thought a person would explode in space if he didn't have a space suit, because there is no pressure on your skin to hold your organs in.
Sep 16, 2012 at 12:09 comment added anna v Since this came up, I heard of an interesting experiment biologists did with a cockroach. In their lab they had a vacuum creating device,which usually was open to air when not in use. One morning they found a cockroach sitting in it and they did an experiment with it creating the vacuum. The roach slowly blew up like a small balloon. They thought "bye bye roach" and let in air. In a little while the roach walked away.

Dec 9, 2011 at 23:04 comment added Keith Thompson @CamJackson: In a vacuum, water can either boil or freeze, depending on the temperature. It can't be in the liquid state at pressures below about 6 millibars (atmospheric pressure is 1000 millibars). The phase diagram of water shows the gory details.
Dec 9, 2011 at 2:37 comment added Cam Jackson Quick clarification: The boiling points lowers as pressure lowers. At zero pressure (a perfect vacuum), water would basically boil at any temperature, even the near-0K of space.
Dec 9, 2011 at 2:30 comment added Cam Jackson I'd just like to add the reason for the boiling saliva: It's not because his saliva somehow got really hot all of a sudden, it's because the boiling point of a substance becomes lower in a low-pressure/vacuum environment. I.e. Your saliva may boil, but it wouldn't burn you.
Dec 8, 2011 at 21:23 comment added nopcorn Thanks for the great answer and references. I tagged it intergalactic-space because it was the most accurate tag I could find. And my reputation doesn't allow tag creation.
