When I was in the 8th grade, all science classes in my school district did a rocketry project.
Teams of 3 chose a rocket from the Estes catalog and built it over a couple weeks in the spring then launched it on a designated day.
I don't recall ANYONE complaining about Sanding Sealer fumes in 1984.
More mamby-pamby nonsense.

Yes, there is such a thing as NORMAL, if you have to ask what is "NORMAL" , you probably aren't !
Failure may not be an OPTION, but it is ALWAYS a POSSIBILITY.
ALL systems are GO for MAYHEM, CHAOS, and HAVOC !
