Although the “look” of this dancing-girl automaton by English toymaker Ron Fuller is not personally to my taste, I could not resist the fact that it is powered by a stream of falling sand, which is a trick I’ve never seen before.

  1. Is there a link somewhere that shows the mechanism I am missing? It mentions it uses falling sand but doesn’t show it. So it’s a trick you still haven’t ‘seen’ :)

    I thought at first the automaton was playing the sound too but is is just on the video right?

      1. @jeff-o:
        You and Pocket-Sized are right on the mark. This technique of using a hopper full of sand to power a water-wheel-like device has been used in automata for hundreds of years. Sometimes the sand it caught in a tray so it can be easily fed back into the hopper without the need to turn it over to reload. I once had the pleasure of operating an automaton from the 1700s that used this principle.

        @Simon:
        Right, the music was added to the video. This automaton doesn’t have any musical element built in.

        Best,
