275 – 32″h X 18″ X 18″ – THREE tracks – Semi Automatic ball release with double helix in center

This is a semi-automatic desktop Rolling Ball Sculpture. Fill the top queue with as many marbles as it will hold – then push the handle at the bottom to release a couple marbles. When a marble reaches the bottom it presses a handle and releases the next marble on it’s own! No lift, no electricity needed to watch this this desktop run on its own. If you release only one marble – this baby will run for over 13 minutes all by itself. Reload the queue at the top and let it go again!
On request this one has a double-helix down the center. Tall skinny coil. Vertical zig-zag. Gravity well. Horizontal zig-zag and lots of great curvy, beautiful track.
