The competition will take place indoors so that no objects will impede, and wind is not a factor in the ball's path. A line will be designated as a launch position. The target will be 25 feet away. A team's catapult will be placed at the launch position and loaded with a s quash ball which will then be fired at the target. The target is composed of concentric rings.
