Engenius Contraptions - Helix vr-id-100903 Great BallAnother 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 thats over two metres in length. The motor driven lift keeps the marbles moving in almost perpetual motion.
