Vietnamese shop, Wood Marble Machine has created an amazing wooden marble contraption that uses gears and lifts to endlessly push marbles down three separate tracks.
There are endless ways to lift a ball high enough to get your marble machine running. If you can get it to the top, gravity will do the rest. With a lift that lifts three or more marbles simultaneously, and releases them to three separate tracks. Two of those tracks are connected in series, so a marble will therefore alternate between those tracks. The third track loops back onto itself.The machine has been designed for 10 mm balls as marbles.
