I personally am not carry a hot cup of something challenged.  I fact after watching the video I think I’d be in more danger of an over enthusiastic NoSpill user clocking me in the head with the silly thing.  You see, this particular thingy uses centripetal force, a physics concept that means an object is forced to move in a curved line, to make the mug remain perfectly balanced. This sucker can carry a mug or glass up to 4.5” wide.

Coolest thing to me is it is American made product by a company out of Virginia available through ThinkGeek for around $15 if you’ve got a yen. According to the manufacturer 'It doesn’t matter how much or how little you move, it will not spill, and that is due to the curvature in the arm of the holder.

But watch the video first.
