Div C Events
Prior to the competition, teams design, build, and test a Roller Coaster track to guide a ball/sphere that uses gravitational potential energy as its sole means of propulsion to travel as close as possible to a Target Time.

Rule 3 (Construction Parameters) - The entire track must not be fully enclosed and the ball should be easily removable for the entire roller coaster, not just the loop in 3.k.ii. For the ball to be considered “easily removable”, the device/track must not have to be manipulated by the Event Supervisor to get the ball out.
