It’s that period again when the nights grow darker and the skies brighten, with fireworks shows taking place all around the country.
Around the world, fireworks are a practically universal emblem of excitement. They are used during festivals, on holidays, and for a variety of other reasons. Hundreds of thousands of people queue to see fireworks displays, and millions of dollars are spent on their purchases.
Fireworks have been fascinating and entertaining humans with large explosions and brilliant colours for years. But the question is, where did it all begin? What are the things you should know about fireworks?
What Is the Story Behind Fireworks?
Firework Originated in China
In China, fireworks have been used since the 7th century. There is, however, proof that ancient Chinese made sparklers since 200 BC.
It’s believed that a cook in China inadvertently produced gunpowder using three basic materials in the kitchen.
The unplanned finding became the forerunner to modern gunpowder and the active element in fireworks. According to findings, China now makes well above 90% of the world’s fireworks today.
Fireworks Was Used at a Royal Wedding in England
Fireworks are thought to have been available in the UK since the late 13th century. However, it only started gaining a large measure of popularity some 200 years later.
The initial recognised use of fireworks in the United Kingdom was during a wedding ceremony of a royal couple
Fun Fact:
In England, there used to be someone assigned to be a Fire Master during Queen Elizabeth’s reign when fireworks fully gained ground across the country. Queen Elizabeth was so enthralled by fireworks that she established the post of “Fire Master of England.” The master was appointed as the head of all royal fireworks shows, being the best fireworks creator in England.
The Colours Are from Chemical Compounds
Although gunpowder remains the primary fuel for fireworks, a variety of chemical compounds – metallic salts/oxides – are used to get the required colours and tones. Yellow, for example, is produced by sodium nitrate, red, by strontium and lithium salts, and purple is by a combination of red and blue-producing chemicals.
Radiative heat transfer causes these additional chemicals to emit light during combustion. The colours we see are caused by radiative heat transfer at specific wavelengths, which vary depending on each compound.
The Initial Fireworks Shows Weren’t Very Sophisticated
Back then, the Chinese did not use colours and had not yet invented projectile explosives, so fireworks displays weren’t the type that lit up the sky and displayed a different style. They just flung the bamboo or paper-wrapped concoction into fires, where it ignited and emitted a series of bursts, similar to today’s firecracker strings.
Can Fireworks Be Harmful?
Fireworks Can Hurt Humans
Each year, thousands of people are wounded by fireworks.
In 2019, according to records, ten thousand people were hurt badly enough in fireworks incidents to need emergency treatment.
Therefore, it’s important to have in mind that while fireworks enhance celebrations, they should be used safely. No one wants a celebration to be interrupted by fatalities caused by fireworks.
Today’s brilliant fireworks displays are absolutely magnificent displays when done well. So you should do it well.
The Colours of Fireworks are Harmful to the Environment
Remember fireworks’ colours are from chemical compounds?
Let’s refresh.
When a specific chemical composition is heated to just the appropriate temperatures, it produces each colour. The colour created is determined by the metal salt used. When the salts and explosives in fireworks come into contact with oxygen, they combust.
Smoke and gases such as carbon dioxide, carbon monoxide, nitrogen dioxide, and sulphur dioxide are emitted when this chemical reaction happens. And these three gases happen to be the most significant greenhouse gases.
Fireworks are detrimental to the environment, and even subject us to dangerous substances and endanger our health. What does this imply? Heavy metals do not miraculously vanish when these fireworks go off. Instead, their atoms become aerosols in the air and poison our air, water, and soil.
Do You Know?
Disney is the world’s largest user of fireworks.
The Walt Disney Company is reported to be the world’s largest user of fireworks. Their displays are projected to cost roughly $50 million per year.
If you ever want to use fireworks, remember:
- Avoid leaving fireworks in the hands of small kids. As for older children, they should use them with adult supervision.
- Avoid using fireworks while under the influence of drugs or alcohol.
- Never use them inside.
- And remember to use them away from people, buildings, and flammable materials.
Preferably, you can choose to avoid any unprofessional mistakes when you light fireworks yourself by going to watch public fireworks displays or watching displays on television.
