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 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. [Areaware via Chip Chick]
