A smoke bomb is a Fireworks designed to produce a large amount of smoke upon ignition.
Colored smoke devices use a formula that consists of an oxidizer (typically potassium nitrate, KNO3), a fuel (generally sugar), a moderator (such as sodium bicarbonate) to keep the reaction from getting too hot, and a powdered organic dye. The burning of this mixture Boiling the dye and forces it out of the device, where it condenses in the atmosphere to form a smoke of finely dispersed particles.
Home-made smoke bombs, even preceding Yale's 1848 invention, were and are most commonly used in pranks and street conflicts. They are typically made from materials that burn poorly and contained in vessels with a limited air intake that inhibit combustion.
