Little Drum is a very cool pocket LEGO Great Ball Contraption designed by the Dutch builder LegoMarbleRun. The mechanism from this LEGO GBC module is quite simple and very clever at the same time: a rotation drum in the middle of the marble run machine is absorbing GBC balls by batch of up to 10 units. Balls are blocked within the drum until it rotates enough to them up onto an upper ramp. Fun to watch, you will love to reproduce this pocket GBC with your kids thanks to Free building instructions that you’ll find on Planet GBC.
