    Supposed to create the illusion that the water is supporting the boulder and making it spin due to the high pressure current.
    but to supply enough water volume and pressure to support a boulder of such mass there would be so much water being sprayed that you'd hardly be able to see the boulder let alone be able to confine it to the small containment pool.
    Still cute to watch though.
    Never try to tell me it can't be done

    If bottom of that rock is spherical(and its "bed" have corresponding shape), then it can work similar way to so called rolling sphere fountain.

    yeah I hadn't considered they my had ground the shape of the bottom to match the fountain. I was thinking more along the lines of a boulder being floated in as rushing river.

    Marv,
    You beat me to posting that link.
    :-)

    And here's one with a world map engraved on it:



    There's one like this at the Nike Campus out here in Oregon - it's about 4' in diameter if my memory serves.
    I saw a decade ago and was blown away.
    Really cool!

    I'd like to lay on top of that boulder and let it rock me to sleep.
