Thanks for the info. It's not really the direction I was looking at. Personally, I wanted to stick with the ultra safe Tannerite product, but get a fireball to go with the report. It might just not be possible, or perhaps it just requires 50 gallons of gas. The Tannerite is the explosive, nothing more necessary in that department, just research into common materials to creating a rolling fireball. We'll keep trying.
Looking through the boomershoot notes, the recipies contain a lot of materials I don't have immediate access to, don't want to pay for, or don't want to grind up (I'm lazy). The preparations require a lot of safety precautions. Other factors including in the prep of those recipies may include sunlight, humidity, storage time, etc.
You could throw one of our bombs in a bonfire and all you would get is a flame up when the fuel ignites, but no boom. We don't have to worry about sparks.
ETA: I think we were successful in our last couple of bombs, but we want a bigger fireball. Video to be link shortly, see for yourself.
