Helix Marble Run is part of the Award Winning Engenius Contraptions range.
Once constructed, the motor-driven lift raises a column of marbles which are then ejected one by one down a mini slide.
As the marbles drop off the slide they land on a series of miniature trampettes, bouncing from one to the next.
The marbles then return to the base of the lift via the spiral hopper.
Easy to build with click-together parts, and made from precision laser-cut plywood.
It’s a brilliant and stimulating construction kit that has a guaranteed wow factor.
The finished size is 800mm x 220mm x 240mm
