Smoke bombs are a firework designed to produce colored smoke upon ignition. While there are smoke generating devices that are dropped from airplanes, the term "smoke bomb" is typically used to describe the three varieties of smoke devices:

Smoke balls - hollow, cherry-sized spheres of brightly-colored clay filled with a smoke composition. They produce a forceful jet of colored smoke for 10-15 seconds.

Smoke candles - (also called a smoke generator or smoke canister) cylindrical cardboard tubes with a fuse, usually 1½ inch (37 mm) in diameter and several inches long and looking like a giant firecracker. Such devices create a thick cloud of smoke for up to several minutes. Uses include providing smoke for smoke testing and creating a smoke-screen for paintball and airsoft games.

Smoke canister - A metal can that releases smoke when a pin is pulled. Used for signalling by military personnel.
