Fireworks

Fireworks are explosive devices that burn with colored flames and sparks. Fireworks are used in pyrotechnic[?] exhibitions and displays.

These devices are used in producing one or more loud bangs or striking displays 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, sulfur, metallic filings, and various salts. 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 sparkling shapes, often variously colored. The skyrocket is a common form of firework. The name is also given to various combustible preparations used in war.
