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 colored smoke. Smoke bombs are often used in various applications, including military training, photography, and special effects in movies. These devices can come in different forms, such as handheld canisters or larger pyrotechnic devices. The smoke produced can serve multiple purposes, such as signaling, creating visual effects, or providing cover in tactical situations. Safety precautions are essential when using smoke bombs, as they can pose fire hazards.
