Rillway Rail

Roll marbles between marble run pylons

The track for the Rillway run: a 230 mm open channel with filleted sides for a 16 mm marble, closed at one end and open at the other. Push the closed end into a high pylon window and the open end into a lower window on the facing pylon, so the stop catches each falling marble and the open end drops it on.
