Windmill Demonstrator

Product Details

This wind power generator can be used to demonstrate the generation of electricitiy by a wind-powered turbine. Wind produced by the hand-cranked fan subsequently turns a second fan connected to a generator. When the fan rotates, it produces electricity and lights up a small bulb, and a connected voltmeter indicates the amount of current being produced. Instructions included. Unit measures 12" x 8-1/2" x 7-1/2". Grades 7-12.
