This hi-tech motor driven marble run is a joy to build, tune and watch it run. Consisting of 173 parts, this helter skelter is sure to keep you busy. Build the tower, then fix the cogs, link the chain, next wind the track, tune the runners, mount the motor and then you’re ready to go. Simply switch on, and off it goes – and goes – and goes – and goes!!


PCNews Verdict: A perfect toy for geeks :)
