Learn the power of the wind, explore gear ratios and more with this 6-in-1 wind-powered machine kit! From the hand powered hand generator to the big-wheel tricycle, walking robot, and yacht, this kit will engage future scientists as they assemble six models (one at a time) from the 200+ pieces. Full-color manual with step-by-step instructions included. You provide diagonal cutters or scissors, nail file, Phillips-head screwdriver, and a few household items.
Build six awesome bots that move without any batteries or electricity. The secret behind these fascinating machines is one of the oldest power sources in the world: wind! A full-color manual guides you in assembling six models one at a time from over 130 pieces. Build a big-wheel tricycle, quadruped, soaring machine, drilling monster, walking robot, and even a wind-powered yacht. To make them all go, the kit also includes the pieces to build a hand-powered wind generator. As you build and experiment, you will learn about how gears transmit power and torque. Also learn about wind as a power-generating technology — past, present, and future.
