An Avalanche of 2,672 Marbles Crash Into a Giant Wall of Wooden Building Bricks

Ortwin Gri1/4ttner (a.k.a. "Murmiland") created an impressive marble run. He set it up so that a single marble rolls down a set of tubes, onto a ramp, and then triggers an avalanche of 2671 marbles that crash into a giant wall of wooden building bricks.
