The machine is made on a solid 2 cm thick beechwood, the battery holder and the switch are engraved on the bottom, and covered with felt. The wheel raises 8 balls/turn, it’s made from wood also and painted black. The balls roll down on copper tracks, which are bent and soldered by hand at the cost of lengthy work. The track has two mechanisms: One divides the balls evenly in two directions, and the other which only drops two balls at once.

Size: 120x100x100 mm, approx 5x4x4 inch.

The machine has adjustable speed! The ornament has a durable 3 mm thick acrylic glass box (also made by hand), which fits on the beechwood plate.
