Techno-balls are meant for those blokes who like to play and take things to bits or for kids to sit down one afternoon and keep dad away from the football.
Great fun to build yet taxing enough to give that huge sense of achievement once the first marble is picked up by the motor and drops it at the top to start the journey down the roller-coaster-like track.

Techno-Balls 920: The ultimate twin-lift set.

These amazing marble-runs are ideal for the techno-mad dad or any mechanically-minded male (or female!). Hours of absorbing fun are guaranteed as they assemble this cleverly-crafted, ingenious power-driven puzzle.
This Techno ball run comes with an enormous 920 pieces to construct together and is guaranteed to keep any techno-minded person entertained for hours as they try and piece the techno balls together piece by piece. The marble run tracks are suspended between the two towers and also driven by 2 motors. This takes the marble right to the top of the helter skelter and releases the marble again and again.

This is the most advanced marble run in our fantastic techno ball range and is for those who are ready for a real challenge.

Simply build the towers, mount the motor, link the chain, and wind the tracks. Span the gaps and you can test your run. Have you built it right? Then switch it on and away it goes!
