Make German Dark Aluminum Powder

These days, it's difficult to find decent instructions on how to make firework ingredients. This Instructable will teach you step-by-step how to make a very important ingredient in some pyrotechnic devices - German Dark aluminum powder. And in a high yield, too! It's called German Dark because it contains charcoal (Carbon), which gives it a darker color. The carbon prevents the aluminum particles from oxidizing, thus making them considerably more reactive. German Dark can and will emit a dazzlingly bright white light when ignited on its own. I give a demonstration of this in the video. Now then, let's make some of the stuff!
