2 Stroke, Rolling Ball Sculpture, is built on a 2 cylinder aluminum engine head as a base and has 2 paths down for the marbles. If you release 1 marble from the top, the total run time is approximately 5 minutes. The real fun begins when you let down 2 (or 3) marbles at a time. They compete with each other to reach the bottom and you feel compelled to lift the marbles out of the tray and place them back on top so that they don't run out.

Aluminum base with stainless steel sculpture above and ten 7/8" glass marbles.
