Set the dominoes in motion and watch as they release a ball and unleash the mighty robot hammer. Watch the whole process from start to finish! As the ball collides with the robot hammer, its potential energy is released, and more dominoes topple before the big flag ending! A finishing flag pops up for a dramatic ending as your last domino falls. Kids will actually be thrilled with the "chain reaction�. The ball unleashes the hammer which pushes over more dominoes and launches the momentum wheel. The transparent tunnel reveals the running process of balls. Watch the Domino effect as your dominoes topple and release a wooden ball into the transparent tunnel.
