Uses
Devices or cartridges containing only the dye are used with an external heat source in a smoke machine.
In the military, smoke bombs are a means for creating smoke-screens.
Smoke bombs are often sold as consumer fireworks, but smoke grenades (with pins rather than external fuses) are not considered fireworks and are usually not sold at fireworks shops. The military-style smoke grenades typically cost much more than smoke bomb fireworks. Military-style smoke grenades often cost around $5–$40 USD, while smoke bombs often cost around 2 to 3 dollars each.
