More on the Mini Solar-Powered Car:
The world's smallest solar powered car - it zooms along when the sun shines on the solar panel. No batteries - it gets its power just from the sun. No assembly required. Measures a tiny 3.3 x 2.2 x 1.4 cm. When the sun shines on the solar panel, the panel makes electricity that turns the motor and the wheels. A fun demonstration of solar power. Will also work when close to a strong artificial light source.
