Crookes Radiometer - All Glass Glow In the Dark Once the game is completeThe Crookes Radiometer or light mill was invented in 1873 by Sir William Crookes. Four vanes are suspended in a globe containing a partial vacuum. The vanes are black on one side, and white or silver on the other. The vanes turn when light hits them. The stronger the light is, the faster they will spin! Even after more than 140 years, there is still controversy about why the Radiometer spins. These elegant Radiometers are made entirely of blown glass.
