Up to two balls in the double kick are waiting for action.
The double kick can set balls 7.5 stones higher in motion. This works with the help of a pendulum. This pendulum is touched by a ball at the bottom, launching the ball at the top in the opposite direction.
The second ball, still at rest at the top, is not released but can be used later. This works, as long as the ball at the bottom doesn't pass through at too high a speed and cause the pendulum to move too rapidly. Higher speeds, in turn, offer the option of releasing both balls.
Scope of delivery:
1x double-kick insert
1x lever
To use both sides, a base stone of the tunnel straight is required.
