Smoke bombs are devices that produce a large volume of smoke when ignited. They are commonly used in various applications, including military training, theatrical performances, and photography. The smoke is created by a chemical reaction that generates colored or white smoke, depending on the materials used. These devices can vary in size and complexity, from simple homemade versions to commercially manufactured products. Smoke bombs are often used for signaling, creating visual effects, or providing cover in tactical situations. Safety precautions are essential when using smoke bombs, as they can pose fire hazards and may release harmful chemicals.
