New Year 2011 Fireworks Around The World

The most common feature of fireworks is a paper or pasteboard tube or casing filled with the combustible material, often pyrotechnic stars. 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, although the first skyrockets were used in war. The aerial shell, however, is the backbone of today's commercial aerial display, and a smaller version for consumer use is known as the festival ball in the United States. Such rocket technology has also been used for the delivery of mail by rocket and is used as propulsion for most model rockets.
History
The earliest documentation of fireworks dates back to 7th century China where they were first used to frighten away evil spirits with their loud sound (鞭炮/鞭砲 biān pào) and to pray for happiness and prosperity.
