Liked on YouTube: Making an Infinite LEGO Domino Ring

A never ending (theoretically) domino ring, built using LEGO bricks. Turn on captions for some commentary on the build.

Building instructions:

1 hour live stream test:

The ring contains 64 dominos. A ramp runs along the inside of the ring, opposite the falling dominos, to lift them back up. A Mindstorms EV3 is used to monitor and control the speed of the ramp so that it matches the falling dominos.
