Another all-new addition to the Engenius range, the ‘Helix’ has been designed with both simplicity and reliability in mind.

An elegant combination of laser-cut plywood parts and paper 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 lift keeps the marbles moving in almost perpetual motion. 'Shortlisted' in the Gift of the Year Awards 2022.
