The Classic Sphere Powered by the Sun!
Set our radiometer (also known as a light mill) in the sun, or bright light, and watch the vanes spin! More light, more spin!
How does it work? The vanes, or wings, in the Radiometer are alternately dark and light in color and set on a spindle in a near vacuum. When the light strikes these wings, it transfers heat to each one - but not to the same degree. The lighter wing reflects the rays, and the dark wing absorbs the rays. This difference causes the big spin!
