I remember reading in Estes literature you could not ignite their motors with a match.
At age 13 I set out to prove them wrong in my BEDROOM.

I placed an unlit wooden match at the top of the grain of a C6-0 motor.
I touched that match atop the grain with the glowing ember of a blown-out but previously lit wooden match. It Ignited EASILY. So much for that BUNK/GUFF/HAWGWARSH/BALONEY of cannot be ignited by a match.

I remember being startled of how large the flame was when burning the motor in "reverse".
Windows were quickly opened. Fans placed in windows to suck out fumes/smoke.
Parents never found out.

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 !
