Ping Pong Parachute
Per the national website:
10/29/19 (Divisions B and C) 5.c. Competition, should read, edits in bold: When called to launch, teams will load their rocket onto the launcher. Once the rocket is loaded, but NOT pressurized, teams will place the parachute payload system on or in the rocket. After the payload parachute system is loaded it cannot be manipulated. Teams will then pressurize the rocket to the pressure (psi) of choice based on their practice log data. At no time should the pressure vessel (bottle) be pressurized beyond 65 psi. The Event Supervisor will check the gauge on the pump to ensure the rocket is pressurized to the psi chosen and justified by the team's data. (A new maximum pressure is now listed)
Although this event could be performed in many types of spaces, the space should have a high ceiling.
1. Timing starts at launch. Timing ends when:
A) Ping Pong Ball touches ground. Note that striking the wall is allowed, and timing only stops when ball touches floor. A device that ‘slides down’ a wall is timed to when the ball touches the floor.
B) Device is stuck on an obstruction at some point above the floor.
2. Tier 3 violation occurs if device strikes the ceiling or anything attached to the ceiling (rafters, girders, fans, etc…). Striking a wall is not a Tier 3 violation.
3. Event supervisors may wish to clarify with their competitors what will be counted as ‘the ceiling’ if obstructions are present. Is the basketball hoop an obstruction or the ceiling? Whatever is chosen, be consistent in the application and let the competitors know ahead of time.
