Satisfying marble run with a vortex

This is no less than a 100 coach train. It seems as if a 100 coach train is moving together in one direction.

I find this satisfying ASF

Just as a snake waves, in the same manner the train is moving at the same speed.

Epic marble run

Humans, these pranks aren't a joke!

Nice

Run baby run

marbles in a vortex - physics or just plain fun?
