1. A fountain apparatus for producing fountain streams and sprays adapted to move in complex oscillatory fashion to provide an aesthetically pleasing and entertaining display, said apparatus comprising:

  • a float provided with a hull adapted for flotation in a body of water;

    a first dual entry nozzle having dual entry ports and a single exit port, said first dual entry nozzle being mounted on said float with its exit port providing an opening in the top of said float;

    a second dual entry nozzle having dual entry ports and a single exit port, said second dual entry nozzle being mounted on said float with its exit port providing an opening in the hull of the float below the waterline;

    liquid supply means for generating and delivering pressured flows of liquid medium from a reservoir of liquid to the dual entry ports of said first and second dual entry nozzles, said liquid supply means including a pump having an outlet port and a conduit system connecting said pump outlet with each of the dual entry ports of said first and second dual entry nozzles; and

    valve means in said conduit system for communicating the outlet of said pump with the dual entry ports of each of said first and second dual entry nozzle in a fashion to produce a nozzle dispersal stream from the exit port of each of said first and second dual entry nozzle which moves in an oscillatory fan-like motion;

    said second dual entry nozzle being mounted in and oriented with respect to said float such that the nozzle dispersal stream from said second dual entry nozzle moves in an oscillatory pivotal motion to thereby produce a thrust force resulting in a reciprocating oscillatory to and fro movement of said float,wherein, the nozzle dispersal stream produced from said first dual entry nozzle ejects upwardly from the hull of said float.
