Step 1: Build a ramp with a steep slope. Step 2: Add the Shooting Gallery section.
The ball must have enough speed and
momentum to knock over the Domino
Planks at the end of the ramp.
An action-packed Contraption
that is sure to impress your audience!
Step 3: Line up the Domino Planks and the
Sitting Ducks and load the Shot Ball. It may
take some trial and error to determine the
perfect position for the Trigger Plank.
Tip: The Domino Planks are precisely
positioned so the Trigger Plank will strike
the Shot Ball and send it sailing toward the
targets (the Sitting Ducks).
