This is a smoke bomb test with a rough 60/40 potassium nitrate/sugar mixture, it is about 40-60 grams. As you can see i've probally added too little baking soda to slow down the burning, but heck, now you can see the nice red potassium flame :) The smoke seems to be a little dark in the beginning which indicates that some sugar was burned, next time i should get it off the fire a little earlier. The smoke doesnt last very long either, that is partialy due to the fact that it isnt much mixture and that it burned with a flame.
