This is a lego GBC (Great Ball Contraption) miniloop. It uses three technic lift arms to push the marbles up a ramp, then they fall onto another ramp. When a second marble falls onto that ramp it tips them down another set of ramps and back down to the start again. I built this miniloop because I wanted it to be easier for people to get into buildin miniloops, as it can be quite hard to build your first GBC on your own. you can watch it running here:
