A smoke bomb is a device that produces a large amount of smoke when ignited. It typically contains a mixture of chemicals that, when burned, create a dense cloud of smoke. Smoke bombs are often used in various applications, including military training, theatrical performances, and photography, to create dramatic effects or to obscure visibility. These devices come in different forms, such as handheld canisters or larger pyrotechnic devices. The smoke produced can be colored or white, depending on the chemicals used. Safety precautions are essential when using smoke bombs, as they can pose fire hazards and may release harmful substances into the air.
