These three Japanese guys use almost anything stackable when they built a domino chain around their house. They used CDs, VHS tapes, toast, bars of soap and more. There were a couple of premature chain reactions along the way but they do manage to get their chain to go from start to finish.
Update: This one is even better. This makeshift domino chain uses a baby ostrich and a monkey! [LINK]
