Fireworks are a beautiful ancient tradition that we know incredibly little about.
Fireworks were invented in China - many people know about it. But the surprising thing is that they were invented before gunpowder. Even before our era in China, they noticed: if you dry bamboo over a fire and overdo it (that is, overheat the stick), then it will explode with a loud "bang bang". The enterprising Chinese used such firecrackers to frighten opponents: imaginary (various evil spirits) and real (wild animals and invaders). Firecrackers and firecrackers are fun, even if you don't believe in evil spirits. Now, fortunately, there is no need to look for bamboo and make fires to get a good burn. New Year is the hottest season for firecrackers.

Fireworks are a box of energy. Explosions and fires result from chemical reactions (namely oxidation, in a simple way - combustion) that release this energy in the form of light. Each chemical element burns up and glows with a special color. To get red fire, strontium and lithium salts are added to the mixture, dazzling white flashes give titanium and magnesium, and green lights are barium. It was relatively late to use different metals for the production of colored fireworks - in the 1830s in Italy.
Bengal lights are an integral attribute of the New Year's celebration and other holidays.
