If for some reason you needed more incentive to take a bath–besides the fact that they're just plain awesome–allow me to introduce to you the 'PowerUp Boat.'
The PowerUp Boat is a conversion kit that transforms your origami boat into an actual seaworthy vessel that Blackbeard himself would use to voyage across the seven seas. This powered paper boat conversion kit supplies you with everything the Captain of a paper ship would need: two sheets of Dupont waterproof printed paper, a quick connect windup motor, a flag, a pirate figure, an anchor and instructions.
The windup mechanism requires no batteries and provides you with up to ten seconds of "propelled fun." Perfect for using in swimming pools, puddles and of course the bathtub.
