No batteries required! Only your breath or a fan will make your 6 robotic builds come alive!
Engineers-to-be will be able to use wind energy to better understand, through play, how this energy source can be converted into motion. The set even comes with a manual fan so you can create your own wind using your muscle power!
A toy for both indoor and outdoor use, kids love being able to build multiple models with one gift! They can build a big-wheel tricycle, a flying machine, drilling vehicle, walking robot, car and even a wind-powered boat!
