Crookes Radiometer by Mindfuel

Witness the captivating dance of light and energy with the Crookes Radiometer! This mesmerizing scientific instrument, invented by Sir William Crookes in 1873, demonstrates the conversion of radiation energy into kinetic energy.

How it Works

Housed within a partially evacuated glass bulb, the radiometer features a delicate set of vanes mounted on a central spindle. Each vane has one side coated in a dark, heat-absorbing material, while the other side remains reflective. When exposed to light, the darker side absorbs more energy, causing the air molecules surrounding it to heat up and exert a greater pressure on that side. This pressure differential propels the vanes into a continuous spinning motion, creating a mesmerizing spectacle.
