Engenius Contraptions: Helix Marble Run

Engenius Contraptions Helix Marble Run is an elegant combination of laser-cut plywood parts and construction straws, this kit is straightforward yet rewarding to build. Inspired by Victorian cast iron engineering, the balls revolve three times around a helical track that’s over two metres in length.
The motor-driven (battery powered) lift keeps the marbles moving in almost perpetual motion. A great STEM product with eco credentials.
