Rolling Ball Sculpture #9 - Watch Video

A two track Rolling Ball Sculpture using 1" (25mm) marbles. It contains a flat spiral, tipping arm and loops. The unique part of the sculpture is, that it has a semi-automatic ball return system. It still requires the operator to move the arm, but the balls roll out on their own. Very interactive, and the children just love it!! I have sculpted this piece so that it fits inside a box, rather than on the outside of a frame. The frame has adjustable feet to ensure that it is always on a flat and level surface.
