Well, I couldn't wait til tomorrow. I practiced on a few pieces of scrap wood with some Calif approved granulated gunpowder. I don't like it much. But at least it shows you what can happen with gunpowder...what happens when you light it...etc. I will be aquiring some real gunpowder next week. The powder kind. This should result in a much more controllable burn and result. As you can see in the video, the result was pretty splotchy, which I think happens because of the granules, and because they are like little flaming balls of joy when you light em and they start dancing around. The true powder form will likely stick to the wood better and the end result will be more uniform. Enjoy. I included a little narrative. I also did the burn in my fire pit...for safety and all, and wore goggles just for fun, because they had cool, yellow lenses. My hands smell like 4th of July. That is all.
