Actually if I were up there I'd be more worried about the lack of pressure, I saw the opportunity and couldn't resists on a more serious note though. Agreed, I know a couple submariners who told me they'd tie a string from one side of the room to the other. As they dove the string would begin to droop and loose tension, a lot of tension. Makes my head spin just thinking about the possibilities, which I'd be doing if I were down there...

> Actually if I were up there I'd be more worried about the lack of pressure Interesting you should mention that. I learned a few days ago that while the ISS at large is kept at 1ATM, the spacesuits they use for spacewalks are only pressurized to a fraction of that (if you pressurize a suit too much, it becomes too balloon-like to easily move). Because of this astronauts/cosmonauts have to spend several hours before each space-walk breathing pure oxygen so that they don't get the bends. That degree of preparation before every spacewalk would disturb me to some extra degree I think. If there was a problem, it's not like somebody else could just hop into another suit and come help you.

  There are several different "pre-breathe protocols" used prior to US spacewalks to avoid the bends. Some involve taking the airlock down to 10.2 psi (as opposed to 14.7 psi for 1 ATM) and sleeping there overnight. Also the crew may hang out in the suit while still in the space station for several hours before the spacewalk. The suit is pressurized with pure oxygen and is at a 4.3 psi. All of this does make for a long day. Even though the spacewalk may only be 6 or 7 hours, entire day with preparations and clean up afterwards is exhausting.
