How Can You Gross-out Your Friends with a Spacesuit?
Phil: Under all of these layers of protection and cool equipment, a spacesuit is really just a big balloon - shaped like your body - which provides a pressurized environment for working in space.
But an "inflated balloon" is hard to twist and bend (he tries to twist and bend a balloon), and a spacesuit's not doing its job unless it let's you move so you can do yours!
The trick is building a spacesuit that doesn't change volume much as you move. That's why this suit has extra fabric wherever you need to bend (he bends his elbow) and ball bearings wherever you need to twist (he twists at the waist).
The flexible design lets me move my arm move like this (Phil rolls shoulder around so that American Flag is underneath arm). Of course you don't want the American Flag in your armpit. We really haven't checked that with the Supreme Court yet - but it can't be a good thing.
Oh yeah, one more cool thing the ball bearings in the wrist are good for. Grossing out your little sister! Check this out (He twists his glove all the way around his wrist). Gets 'em every time!
