LEGO Great Ball Contraption - GBC hourGlass, by tomas Ullrich | planet GBC

GBC HourGlass

GBC HourGlass is an astonishing LEGO Great Ball Contraption from Tomas Ullrich. In this crazy-cool LEGO marble run machine, your GBC balls are going to do several 360° turns within some vertical tubes looking like hourglass. A vertical conveyor placed on top of the entry ramp in injecting the balls, one by one, into the main hourglass structure. The rotations of the transparent hourglass structure is then doing the rest: whenever it does a full turn, GBC balls are shifting by one position towards the exit ramp. After eight full rotations, your favorite LEGO basket and soccer balls are released. Rush to discover this brilliant mechanism on the YouTube channel from Tomas.
