Description

Description:

This Crooks Radiometer is made of glass and the interior is close to vacuum. It can rotate on its own through light, and it can also turn in the opposite direction through cold wind. It is a magical scientific exploration teaching instrument with a height of 205mm, a sphere diameter of 90mm, and a base diameter of 80mm.
 

Principle:

When the black vane surface absorbs heat energy if it is illuminated, the white vane surface releases heat energy, vanes transfer heat to each one but not at the same degree, which can push the four leaf surfaces to rotate. This physical and technical miracle shows you in a clear way how sunlight is converted to energy. To make the testing you can place it near a window or under incandescent light and the vanes will rotate.
