Assemble one of the most complex mechanisms ever fitted to a model. The upwards movement of marbles up the track is powered by one single motor which, via a network of gears and rods, allows for 3-axis movement of the conveyor.
The pre loading of the marbles is done via a staircase-style mechanism, powered by the same motor. Once assembled you'll get lost for hours in the complexity of it all, a mesmerising dance of gears, cogs & rods.
Once all marbles make it through simply dump them back into the starting position and get lost in the movement all over again!
