We picked this kit for a hands-on (and battery-less) learning experience on the value of renewable resources. It uses green science to light an LED bulb – all you need to add is a recycled soda bottle.
The kit includes a rotor, the front housing with the gear and rotor shaft pre-installed, the back housing, tail, the toy motor, and cover, screws, LED unit, and detailed assembly instructions, plus fun facts about renewable energy. Pro-tip: Use a blow-dryer for maximum wind-harnessing and LED lighting power!
