Explosions in the Sky
If you attend a major outdoor event in the evening, whether it is in Paris, Beijing, or New York City, there is a good chance that it will end in a sensational way. After all of the other activities have concluded, the sky will be lit up by a colourful firework display. Although the show may only last for a few minutes, during that time every eye will look on with amazement as they work their magic in the air. Fireworks were invented in the seventh century by the Chinese. They were quickly absorbed into the culture and became a part of many celebratory events and festivals. Eventually, emperors would organize large firework displays to entertain and impress their subjects. Fireworks didn’t become big in Europe until the mid-17th century. People became interested in fireworks after reading accounts from monks and travellers who saw them while in China. Once they did arrive, it was obvious they were there to stay. Fireworks were frequently paired with triumphant classical symphonies to celebrate the end of wars and other great victories. As time went on, the fireworks continued to evolve and get better in many ways. Fireworks now come in every colour imaginable. The colour comes from different chemicals that are placed inside of each firework. Thanks to modern technology, it is also possible to create firework arrangements in the shape of hearts, smiley faces, and even the planet Saturn. This is because of the way that the aerial shells, or casings, of fireworks are constructed. The cases are packed with exploding pellets and a piece of cardboard. The cardboard enables the designers to arrange the pellets in pattern or shape of the object of their choice. The first time this technology was used was in Washington DC, during a celebration to welcome home American troops who fought in the Gulf War. The visual aspect is only part of the reason fireworks are appealing. The sounds that fireworks make also add a healthy dose of excitement to the display. There are several noises that fireworks can make. The most common is the “bang” which sounds a lot like a gunshot. Fireworks can also crackle, hum, and whistle as they streak across the night sky. The world’s largest firework show was held in Kuwait in 2012. 77,282 fireworks exploded during the incredible 64-minute show. But with people’s love for fireworks at an all-time high, who knows how long that record will last?
