A fireworks show is a beautiful display of chemistry art. Fireworks were developed out of the Tang Dynasty in the 7th century.

The energy output releases as color, sound, light, pressure

mother got sick, so instead of our usual Fourth of July tradition of popping fireworks at our grandmothers house, we were stuck at home. The plan was to wait until our mother felt better to go pop fireworks, so like good children, my brothers and I nodded our heads and went off to play, and that lasted for about maybe twenty minutes before we got bored. My brothers Colten and Tyler had the bright idea to steal the fireworks and walk around the neighborhood, and I being about six at the time thought

Fireworks don’t just look stunning they are also quite educational! The chemistry that goes into building fireworks is complex and interesting. It can even be a fun way to teach children about the basics of chemistry with some fun experiments. Here are some of our favourite chemistry experiments to make with children – whether you are a science teacher or a parent looking to entertain your kids!

Date: November 17, 2017 Every 4th of July, many people go out at night and spend hours watching firework shows. Most of us are content to simply enjoy the pretty colors and sparks, without questioning the chemistry behind the spectacle, but have you ever really thought about how fireworks produce such vibrant colors? The colors emitted when a firework explodes come from an aerial shell inside the firework that contains explosive chemicals and metallic salts. These colors appear to us because of luminescence

report The Chinese fireworks industry has experienced significant change since China adopted "open door policy", moreover, it has huge market share in the world's fireworks market.

After black powder was discovered by the Chinese in the 9th Century, the relatively short history of fireworks began with this explosive chemical composition. Black powder is made up of potassium nitrate, sulfur, and charcoal (KNO3); in the correct amounts, this combination has very explosive results. The use of black powder sprung forth the evolution of muskets, rockets, and fireworks. Although history has shown that the development of black powder muskets into modern day guns, artillery, and weapons

the Fireworks by Grucci compound evokes a military test range of the desert West. A network of lonely gravel roads is studded with metal shipping containers, or "magazines," each containing the raw materials of fireworks displays, ringed by hulking berms to prevent a chain of accidental explosions. In nearby cinder-block buildings, specialists wearing static-free clothing are at work "packing programs," or assembling the sequences of color and sound that will embroider the night sky for some future
