A wetsuit is a diving suit that isn't waterproof, but it still keeps you warm. The small amount of water that gets in is warmed with body heat and is also insulated from the cold outside the suit. This guy went swimming in a pool in a wetsuit -don't ask me why- and it appears that the water got into the suit a whole lot easier than it's getting out. Maybe he borrowed a suit that's too big for him.
Look! He's turned himself into a water slinky! That has to be frustrating. And heavy, too. But he made us laugh, so that's worth something. -via Digg
