WindBots: 6-in-1 Wind Powered Machine Kit

Available from Snapdoodle Toys & Games Seattle when we last checked. Sold from the shop’s own store; the price there is the one that counts.

Build robots powered entirely by the wind! A big-wheel tricycle, a quadruped, a soaring machine, a drilling monster, a walking robot, and even a wind-powered yacht... The full-color manual guides kids along as they build each one. Plus, they'll discover the science that makes them work! They'll learn how gears transmit power and torque. They'll explore the past, present, and future of wind as a power-generating technology. And if there isn't any wind in their house, there's no need to worry. Wit
