Description
| Fun Science Radiometer Dome Spinning on the windowsill. If you put it on the windowsill on a sunny day, the wings inside it will spin around lightly. The principle is complicated, but it looks very light. Principle of spinning One side of the feather inside the glass is painted black. When exposed to light, the black surface of the feather absorbs the light and becomes hotter. Molecular activity of the gas near the surface becomes active, and the pressure due to molecular collisions on the surface of the vane differs from that on the other surface, causing the vane to rotate toward the unpainted surface. (The inside of the glass sphere is in a semi-vacuum state.) |
