Demonstrates the sun's energy. When in sunlight or artificial light, the vanes rotate at a high rate of speed. When in darkness the vanes cease movement altogether, showing the simple principle of energy from the sun can be converted into motor energy. This device gives your students the benefit of seeing the bombardment of molecules within a near vacuum. Comes with complete sheet cataloging known and unknown factors about energy. Our Radiometer is made from a glass bulb from which much of the air has been removed. Inside the bulb, on a low-friction spindle, is a rotor with 4 vanes. Each vane has one blackened side and one silvered side; one black vane features a white dot in order to count rotations easily.
