Made eight "smoke bombs" today, with my own formula, I found a trick to getting the material to bind together better, and instead of forming that ugly and hard "caramel" type appearance that's nearly impossible to work with, I have been able to get it to look more like thick petroleum jelly, that can be fit into containers, spread about, and molded. I set a small one off, and it burned strong for a good minute, although the smoke wasn't very thick and it took a bit to catch fire, (it was a small one down the tube, so there was limited Oxygen for good ignition). The larger ones that are packed better catch well. I made my own fuses/wicks out of a twin and my own alcohol solution.
