Use stored potential energy to catapult a wooden ball into the air with this exciting robot-themed domino set!

A tipper car, crazy ball track, tipper arm and series of ramps form an exciting robot production line that you can build again and again.

1. Start by building one of the configurations shown on the box.
2. Put a wooden ball in the rail car and release it down the ramp. As the car tips over, the ball is released and starts the Domino Effect. Watch the momentum wheel turn before the catapult fires another ball into the air, starting more dominoes tumbling. Momentum flows through the spinning arm and gravity release arm and into the third ball that navigates a zig-zag track before triggering the see-saw and shooting it the marble into the flag finish box.
3. Now, unleash your imagination by building new trail configurations.
