do you enjoy watching fireworks?  

A fireworks event (also called a fireworks display or fireworks show) is a spectacular display of the effects produced by firework devices on various occasions. Fireworks competitions are also regularly held at a number of places.
Fireworks probably originated in China (206 BC–AD 220) and produced 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 to dispel evil but also to pray for happiness and prosperity.

Taoist monks played with the basic components of gunpowder to create fireworks in their spare time. Eventually, the art and science of firework making developed into an independent profession of its own. In ancient China, pyrotechnicians (firework-masters) were well-respected for their knowledge and skill to mount dazzling displays of light and sound. Some scholars say fireworks were developed in the Sui and Tang Dynasties (581–907), but others argue there were no fireworks until the Northern Song Dynasty (10th century).
Since then, any event—a birth, death, wedding, coronation, or New Year's Eve celebration—has become a fitting occasion for noisemakers.
Amédée-François Frézier published a "Treatise on Fireworks" in 1706. In this treatise, Frézier studied the recreational and ceremonial uses of fireworks, rather than their military uses. The book became a standard text for fireworks makers.
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.

The World Showcase Lagoon at Epcot during IllumiNations: Reflections of Earth, the nightly fireworks showThe largest manufacturer and exporter of fireworks in the world is China. China is estimated to have exported over 6 million cases or 120,000 tonnes of fireworks to the US in 2005.
In 2004, Disneyland in Anaheim, California, started using aerial fireworks launched with compressed air rather than gunpowder, the first time that such a launch system was used commercially. The display shell is detonated in the air using an electronic timer. The advantages of compressed air launch are a reduction in fumes, and much greater accuracy in height and timing.
This is the history of fireworks from the period where they were introduced in competitions to nowadays big events where the spectacle of watching fireworks is guaranteed.Best wishes
