The vanes are blackened on one side, and they rotate when exposed to strong light. Just place the bulb in the sun, or next to a lamp, or any other healthy light source, and watch the vanes spin faster and faster according to the light's intensity. No batteries are required - the light makes it go! Learn the mysteries of light, mechanical, and heat energy (but most of all have FUN) with the amazing Radiometer.
