Kids today demand more from their toys, since mobile devices have freed them from the burdens of imagination. So if you were thinking of introducing your kids to the DIY joys of origami, the wonders of seeing a paper boat actually float won't be enough. You'll also need this tiny outboard motor so it can cruise around your bathtub on its own.

From the same folks who brought us the electric motor for paper planes comes this miniature wind-up wonder—the PowerUp Boat—which clips onto the back of a paper boat and propels it for up to ten seconds. No batteries required, and the $12 kit even includes waterproof Dupont paper so your paper pirate ship doesn't get soaked and sink minutes after launch. [PowerUp Toys]
