NEW! Due Sept 2018
Instantly captivating, this Engenius Contraption is a flat-pack marble run made from plywood that you assemble yourself.
Powered by an electric motor, the marbles are raised to the top of the lift...first descending down the spiral then down the zig-zag track...then the spiral, then the zig-zag...in a mesmerising perpetual motion.
It is a puzzle to construct and a joy to see in action!
