Hang Time

Q1. For Hang Time: Is hot glue allowed in the construction of the parachute? I understand it is not allowed for rocket construction as it can change or weaken the chemical make up of the bottle. Thank you.

A1. As written, the Detailed Event Description allows glue but forbids the use of hot glue and super glue.  We will take this under advisement for future revisions of the event.  In the mean time you can still use white glue, tape, sewing, etc to construct a parachute.


Q2. I’m coaching 5th grade Hang Time, and my students wanted to create an anchor (basically a weight made out of clay) on a string that would trail behind the rocket, pulling it down and away from the payload at a certain point in its flight. Would this violate the rules surrounding kinetic and potential energy that govern the event?

A2. The rule referred to in L7 talks about the energy to *launch* the rocket and is written to ask participants to avoid external sources of thrust.  There is no upward force (thrust) to be gained from a clay anchor.  This idea does not violate the rules but we would caution you to test it thoroughly as any sort of extra strings hanging off the rocket could potentially get caught up in the launcher and cause a launching malfunction.
