Description & Details

The Radiometer uses the power of science to create some fun kinetic motion. When this solar motion toy is in direct sunlight, the top spins. The spinning action is caused because the sunlight is reflected off the lighter colored blades and is absorbed by the darker blades. Keep a Radiometer on your desk to watch the energy of light in motion!
