A device for producing a striking display of light, or a figure or figures in plain or colored fire, by the combustion of materials that burn in some peculiar manner, as gunpowder, sulphur, metallic filings, and various salts; also called a pyrotechnic device. The most common feature of fireworks is a paper or pasteboard tube filled with the combustible material. A number of these tubes or cases are often combined so as to make, when kindled, a great variety of figures in fire, often variously colored. The skyrocket is a common form of firework. The art of designing fireworks for purposes of entertainment is called pyrotechnics. The name firework is also given to various combustible preparations used in war.
A device containing pyrotechnic composition that produces audible and visual effects through combustion. All fireworks devices work by combustion, which make all fireworks potentially dangerous if mishandled. Fireworks should only be handled by responsible adults who follow all suggested fireworks safety guidelines.
