Ball Pump machines are very popular in the world of Great Ball Contraption. Pinwheel has brilliantly taken up the challenge to propose you his own version called Reveal Ball Pump, aiming to visually show how a ball pump works. The principle of this LEGO marble run machine is similar to other ball pumps: the GBC balls are stacking, progressively pushed to the top of the module to an exit ramp. The asymetric design of the module and the usage of trans-clear panels allow viewers to watch the smart and compact mechanism from this cool LEGO build. You can reproduce it thanks to free building instructions provided by Pinwheel.
