Relay Stairs

Carry a falling domino chain up and over

A folded ribbon staircase for domino runs: six 10 mm steps up and six down, with 20 mm treads that hold a standing domino each. A domino chain climbs over the summit and runs on down the far side, a classic chain reaction trick made neat and repeatable.
