Heron's Fountain - Construction

Construction

Heron's fountain is built as follows:

  • Start with a basin, open to the air. Run a pipe from a hole in the bottom of that basin to an airtight air supply container. (Glass flasks are shown here, and serve the purpose well. Cans with airtight lids may also be used.) The air supply container stands significantly below the basin.
  • Run another pipe from the top of that container up to the top of the airtight fountain supply container, which is filled with water.
  • From the fountain supply container, have a pipe that reaches nearly to the bottom of the container, through the top up to the spout of the fountain. A refinement is to have the spout coming up through the centre of the basin, and the containers may be concealed in a column supporting the basin, as long as the air supply container is lower than the fountain supply container.
  • Fill the basin with water.
  • The water from the basin flows by gravity into the air supply container. It fills the container, displacing the air.
  • The air flows into the fountain supply container, displacing the water, which shoots out higher than the original basin.
  • The flow will stop when the water supply container is empty (i.e. when the water level drops below the lower end of the outlet pipe).

Famous quotes containing the word construction:

    “No real “vital” character in fiction is altogether a conscious construction of the author. On the contrary, it may be a sort of parasitic growth upon the author’s personality, developing by internal necessity as much as by external addition.”
    —T.S. (Thomas Stearns)

    “No construction stiff working overtime takes more stress and straining than we did just to stay high.”
    —Gus Van Sant, U.S. screenwriter and director, and Dan Yost. Bob Hughes (Matt Dillon)

    “When the leaders choose to make themselves bidders at an auction of popularity, their talents, in the construction of the state, will be of no service. They will become flatterers instead of legislators; the instruments, not the guides, of the people.”
    —Edmund Burke (1729–1797)
