Fireworks \nFireworks 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 \nof materials that burn in some peculiar manner, as gunpowder, sulfur, metallic filings, and various salts. The most common \nfeature of fireworks is a paper or pasteboard tube filled with the combustible material. A number of these tubes or cases are often \ncombined so as to make, when kindled, a great variety of sparkling shapes, often variously colored. The skyrocket is a common form \nof firework. The name is also given to various combustible preparations used in war.
Improper use of fireworks may be dangerous, both to the person operating them (risks of burns and wounds) and to bystanders; in addition, they may start a fire if landing on flammable material. For this reason, the use of fireworks is generally legally restricted. In some jurisdictions, their use is restricted to professionals; in some others, some smaller models can be used by the general public, while the others may only be operated by professionals. Also, in general, firing them near houses or in fire hazards areas is prohibited.
History of fireworks\n
In the Han Dynasty (206–220 BC) firecrackers were made by roasting bamboo to produce the loud sound (known as "bian pao") that was intended to frighten evil spirits. In the Northern and Southern Dynasties (AD 420–581) the firecrackers were used not only used to dispel evil but also to pray for happiness and prosperity.
The discovery of gunpowder and the invention of the first true fireworks are traditionally credited to the Chinese, although India is also a likely source. Some scholars believe fireworks were developed in the Sui and Tang Dynasties (581–907), but others believe there were no fireworks until the Northern Song Dynasty (10th century).
Since then, any event -- a birth, death, wedding, coronation, or New Year's celebration — has become a fitting occasion for noisemakers.
Musick for the Royal Fireworks, was composed by George Frideric Handel in 1749 to celebrate the peace of Treaty of Aix-la-Chapelle, which had been declared the previous year.
America's earliest settlers brought their enthusiasm for fireworks to the United States. Fireworks and black powder were used to celebrate important events long before the American Revolutionary War. The very first celebrations of Independence Day were in 1777, six years before Americans knew whether the new nation would survive the war; fireworks were a part of those festivities. In 1789, George Washington's inauguration was also accompanied by a fireworks display. This early fascination with their noise and color continues today.
