  • One of his inventions was a fountain that functioned without any aid.

Description

  • Hero’s Fountain worked by water falling onto an empty pressure chamber forcing air up into a second water container, below the first.
  • The pressure of which, forced the water up through a narrow tube, producing a jet of water, higher than the top basin.
  • The fountain continued until the top basin had run out of water.
  • It was not a Perpetual Motion machine as the top basin had to be constantly replenished.
