Wait until you see it in the motor and rocket! This stuff is just amazing. I was afraid the aluminum was too low, but its just spot on withe the oxidizer ratios. Very little losses to agglomeration and condensed phase flow.
Gotta get that Mavericks Gold formulation dialed up next. Will have to move to a steel casing though, to take the MEOP.
Sorry about your fire pit. Replace it with an old washing machine tub. They are low carbon steel and have a higher melting point. Only problem though, is that with the high oxidizer ratios you will get a secondary thermite reaction with the aluminum in the propellant.
Sounds like fun!!!!

I imagine you never made it to the marshmallows! That is some intense bonfire!

Copper lasts a lot longer than iron alloys in the salty air of the sea-side bluffs.
As for the inspiration, yes!!!! That is exactly what motivates Tom. Check out the video at RocketMavericks.
So many people have contacted me since my TED video went up to relay how rocketry inspired them in their childhood. There have been over 500 million Estes rocket launches in the U.S. alone.
Rocket science is tangible. Here’s a beginner’s propellant primer for the curious.
Dr. Dad: we started with marshmellows and smores…. with a clear breakpoint between eating and chemical fires…. =)
Here are the extra photos from the burn… The P-size solid rocket motor grain is the cylinder in the middle:
It burned right through the metal fire pit, and glazed the gravel. Here is the post-burn glow:
Looking out the burn hole this morning:
Molten copper drippings (at the bottom… I have them on my desk now:

Steve you could have lied and told us this was your recipe for chili!
