Experience this sphere powered by the sun! The vanes in the Radiometer alternate between dark and light in color. When the light strikes these vanes it transfers heat to each one - but not at the same degree. The lighter vane reflects the rays and the darker vane absorbs the rays. This causes the vanes to spin. The stronger the light, the faster they spin.
