Watch NASA inflate the space station's expandable habitat

It is about time they got around to it. If you have ever seen a mockup of the space station you know that 10' diameter cylinder that is 13' deep is huge.

And with no equipment on the walls it could be a good place to try out activities where you might bump uncontrollably into the wall by accident :-) Either way, its going to be a really interesting space to hang out in.
