This Wind Powered Generator demonstrates the production of electricity by a wind powered turbine. Wind that is produced by the hand-cranked fan turns a second red-colored fan when positioned directly in front of the hand cranked one. When the red-colored fan rotates, it produces electricity and lights the bulb in the circuit. The power generated is also registered on the voltmeter. An instruction manual is provided. Dimensions: 8.5" x 5.25" x 5"
