Color Changing Waterfight Vest   (+6, -1)  [vote for, against]
A vest or breastplate that changes color to bright red when hit with cold water.

Plastics that change color with temperature changes are readily available. Form them into breastplates or vests that can be worn during summer afternoon water fights to show who has been recently hit.

Any bets on how long it takes one of the toy companies to scoop this idea?

Cloths are available that do this, too. Hypercolor I think was the brand name of these T-Shirts, back in the 80s.
