The unique shape of this stainless steel flask makes it look like a blood bag full of life-giving serum for the T-1000 from Terminator 2, and that's not too far from the truth. The prototype for the Liquid Body Flask—designed by the folks at The Principals—was actually created by pumping water into a couple of panels of stainless steel welded together at the edges until they inflated like a water balloon.

But instead of blood or liquid metal, you can fill this flask with whatever life-sustaining liquid you choose; be it water, booze, or Hawaiian Punch. It won't officially be available for sale until November, though, so you might want to consider a pair of flask mittens first as the weather gets colder. [Areaware via Chip Chick]
