Description

How do the vanes turn under no apparent power?

  • Made from a glass bulb from which much of the air has been removed

  • Each vane has blackened side and silvered side
  • Heating by sunlight or artificial light makes vane rotate
  • Differential heating of the two sides results and creates the motion
