In the past few years, we have covered plenty of awesome marble machines here. The Clip Clop Large Marble Pyramid is also worth a look. It stands 40″ tall and puts on a mesmerizing show as the marbles move from top to bottom. This piece has steps, bells, chutes and spirals for marbles to travel through.
These marble machines are Amish handmade and ship with the marbles you need to start playing.
