I learned some really fascinating things today. (c: Heh. If you are in an airplane and you lose cabin pressure, don't hold your breath. Exhale as well as you are able. The gas in your lungs can be lethal if you allow it to expand. So let it out! Also, dress warm on flights because it's cold enough already, and if you lose cabin pressure, it gets REALLY cold.. like.. frosbite. Not pleasant.
And for all of you who thought your blood would boil if you were ejected into the vacuum of space, well... you're wrong. A human can actually maintain consciousness for about 9-11 seconds in a vacuum. Even after that, animals who've been subjected to a near absolute vacuum have survived up to two minutes in such conditions. (I think making surprisingly good recoveries.) Amazing! So, don't hold your breath, and act quick to restore pressure if you somehow find yourself in a low atmospheric pressure condition.
One account I read about someone who was subjected to a near vacuum pressures said that among the last things the guy experienced before blacking out was the water boiling on his tongue. Weird!

I am kind of wondering what inspired this frenzy of investigation into a topic I had never even thought of. Umm, do airplanes often lose cabin pressure and then restore it? I thought most people in a serious airplane situation worried more about impact than frostbite...
so, when flying, what exactly should I fear most?
this is another piece of lint in the bellybutton of life...
yup! Uh.. I'd say don't fear anything if you're a christian and fear everything if you aren't. (c: Heh.
As to what inspired looking and finding this out.. well, i'm a curious sort. So I started looking up the atmosphere of Mars, because I wanted to know how close it is to "sustainable" (not very). And I later found out that Venus has a sustainable place in it's atmosphere for humans... in a balloon. And it went on from there until I found out that humans won't die in a vacuum. (c:
This is starting to feel like Friday Facts. =D
Also, don't worry about all those complicated instructions for how to handle a water landing, since in the history of aviation there has never been a water landing in which passengers survived.
hey, that's good to know, phil!
another anecdote regarding an airplane and a rapid change in air pressure is that it would very quickly form a fog in the cabin itself, so you will, 1) Get really cold, 2) Not be able to see much and 3) Probably will kill you if you hold your breath or crash into water. Amazing!
I have a nearly 7 year old with this same inherited curiousity. (Inherited from both sides.) It was only 7:30am and I already had to look up what the largest counties are in this world. Thankfully, he can't read your blog without help so I won't have to be answering questions about surviving in a vacuum!
Hey Luke, thats a bit of a stranger post, where did you get this info from? Didnt no they were allowed to do such tests on animals? What inspired you into this topic?
Anyways mate really wanted to wish you a very happy b-day 3rd Nov hope u had a great day! What did you get up to?
