Thinking about a couple of thermal and gas laws demonstrations I want to conduct with the kiddos at school. Part of the agreement with admin is that the students will conduct themselves under the NAR safety code. NAR stipulates:
1. Is "body" open to interpretation and excluding internals
2. Would a 3" long, 3/4 piece of perforated (drilled) aluminum tubing joined at the lower end of a B-D motor, strictly as an exhaust duct, be a no-go
What is the prevailing consensus/interpretation?
- Materials. I will use only lightweight, non-metal parts for the nose, body, and fins of my rocket.
