Thames & Kosmos, LLC Wind Powered Machine Kit

The Wind Powered Machine Kit lets you build 6 moving toys that harness the eco-friendly power of the wind. Instead of batteries, a built-in turbine creates electricity for 6 kid-friendly engineering projects, including a big-wheel tricycle, quadruped, soaring machine, drilling monster, walking robot and yacht. If there's no wind, you can make your own with the included handcrank fan. Includes 130 pieces and a full-color, easy-to-follow guide. Ages 8+.
