Crookes Radiometer

The sight of the blades turning around in the sunlight is very interesting, no external power source is needed.
The radiometer, also known as light mill, was invented by English physicist Sir William Crookes (1832-1919).
The the point is that there is a vacuum in the glass dome, one side of the paddle wheels placed on a spike is shiny, the other is matte black, so they start spinning under the influence of the warm light.

Does not require battery or external power source.
