Today is 4th of July…! Americans celebrate their country’s Independence. Happy Independence Day Americans…!
4th of July is known as Independence Day in United States, It’s one of the biggest holidays in the US calendar since 1941. But the tradition dates back to 18th century. On July 2nd 1776 the continental congress voted in favor of independence, and two days later delegates from the 13 Colonies of America declared themselves states and no longer part of the British Empire. The Revolutionary War continued for awhile after though.
How do they celebrate?
It’s historically important for Americans, but it has also become a huge holiday celebration with parties and events across the country in every state. The day is commonly associated with fireworks, parades, barbecues and picnics, family reunions and baseball games. It’s an excuse – or reason – to go all out and celebrate.
For many Americans, the Fourth of July wouldn’t be the same without a dazzling display of fireworks. Then we should know from where the so called “red rockets” or “the bomb bursting in air” or “fireworks” people have been awed by the bright lights.
Chinese people made the first fireworks by filling bamboo shoots with gunpowder and exploding them at the New Year or any festival with the hope that the sound would scare away evil spirits.
Now I am going to tell you the basic thing about fireworks.
Above pic explains about basics of fireworks…
Fire color by chemical
Early fireworks were enjoyed more for the sound than the show in its simplest forms gunpowder explodes quickly, leaving a terrific bang but not much to see other than a brief golden glow. Over time people discovered that using chemical compounds with greater amounts of oxygen made the explosives burn brighter and longer.
Adding trace amounts of metals that burn at high temperatures, creating beautiful colors. Other additives also produced interesting effects. For example, calcium deepens colors, titanium makes sparks, and zinc creates smoke clouds.
Here you can see which color is produced by which compound or metal.
You got to know how fireworks got color?? So many things we can do from Chemicals right? Yeah… We are living in Chemical World itself… 🙂
