About this product

From Stirlingkit's product listing:

Crooks Radiometer Solar Light Mill Amazing Science Toys Features: .Invented by the chemist Sir William Crookes in 1873, as a by-product of certain chemical research, radiometers are made of glass bulbs, most of which have been removed to form a partial vacuum. .Inside the bulb, on the low-friction main shaft, is a rotor with several (usually four) vertical lightweight metal blades distributed equidistantly around the shaft. One side of the blade is polished or white, and the other side is black. .When exposed to sunlight, artificial light or infrared radiation (even the heat of nearby hands is enough), the blades rotate without obvious power, the dark side retreats from the radiation source, and the bright side moves forward. Just place it near a window or directly under an incandescent lamp, because the blades only rotate under the light (sunlight or incandescent lamp). .Light Pressure
