A variation on the saltpeter/sugar recipe is to replace the granulated sugar with powdered sugar (icing sugar). The powdered sugar and potassium nitrate are sifted or mixed together and left in powdered form. The powder is ignited to form smoke.
Zinc & Sulfur Smoke Bomb
Mix the zinc and sulfur. Insert a red-hot wire to ignite the mixture and produce smoke. This is a particularly smelly smoke bomb.
Black Powder Smoke Bombs
Black powder (gunpowder) or pyrodex can be mixed with other substances to produce a lot of smoke:
- as a powder, mixed with sugar and sulfur
- mixed with sawdust
- with sugar, sulfur, and a bit of material from a road flare (red flame)
It's easy to make a colored smoke bomb...
