In a vacuum the boiling point drops of all liquids drops significantly so your body temperature is more than enough to boil the saliva off of your tongue.

I'm sure it'd be quite the sensation, assuming your stomach contents weren't also forced out at the same moment.

Thank you! I always wondered why your tongue would boil in a vacuum, and now I dont have the bother searching on Google

There's a video somewhere on the net of the actual experiment where the guy survived being in a vacuum. There was a malfunction in his suit while he was in a testing chamber, if I remember rightly he collapsed after a few seconds, but after he was dragged out he recovered and was ok.

Might help a bit

Shown on a series called "Moon Machines," in the episode detailing the development of the apollo space suit.

Open the airlock HAL.

There's a short story by Arthur C. Clarke on that subject, called "Take a deep breath".

Now you're talking my language. Me and A-Clark (that's my little nickname for him) go way back. Like 5th-grade back. My hero.

I'm afraid I can't do that... Dave.

Ummm... you ARE aware of why people think he moved to Sri Lanka, aren't you?

^Is it weird that I find honor in that he passed away on my birthday?

He had to go at some point. He led a long and fruitful life. If he was going to die, might as well be on a day that forever ties him to me in my heart!

The boiling point is directly linked to atmospheric pressure. Higher PSI = higher boiling point. Lower PSI = lower boiling point.

A lot of people make the assumption that water boiling in a vacuum is "boiling hot", as in ~100C. The water doesn't get hotter in the vacuum, it boils at a lower temperature. It's one of those things that you can explain to people until you're blue in the face and they'll just never get it.

By the way, the correct response to this question is "upright or canister?"

You son of a bitch. I had to look that up. I didn't need to know that!

Not to nit-pick or reveal my extreme level of nerd-ish-ness but, I believe it's Pod Bay Door

Pretty sure everything liquid starts to boil (or vaporize), including your blood. So you essentially get the bends.

That's not actually true. Blood is kept pressurized by the vascular system. By the time you lost enough blood pressure for it to actually boil, you'd already be dead.
