When the night sky is lit up by brilliant lights and shocking explosions come one after another, are you curious about why people set off fireworks when celebrating? What little-known stories are hidden behind fireworks, a brilliant symbol that combines history, culture and science?
Where did fireworks originate?
The history of fireworks can be traced back to the Han Dynasty in China in 200 BC. At that time, alchemists accidentally discovered the principle of gunpowder while experimenting with chemicals such as saltpeter, sulfur and charcoal. Legend has it that an alchemist put these mixtures into bamboo tubes, resulting in a huge explosion and brilliant flames. This accidental discovery opened the history of fireworks and firecrackers.
Why do people set off fireworks when celebrating?
The tradition of setting off fireworks originated from people’s yearning for a better life and the expulsion of evil forces. In traditional Chinese culture, the sound of firecrackers is believed to drive away evil spirits and bring good luck. This custom gradually evolved into setting off fireworks during festivals and celebrations, symbolizing joy and reunion. As the technology of fireworks spread, people around the world began to use fireworks at important moments to celebrate victory, independence and the arrival of the new year.
What are the scientific principles behind the colors of fireworks?
Are you curious about why fireworks can present different colors such as red, green and blue? This is related to the combustion reaction of chemical elements. Different metal salts emit specific light at high temperatures:
- Strontium salts: produce red flames
- Barium salts: produce green flames
- Copper salts: produce blue flames
- Sodium salts: produce yellow flames
Fireworks makers create colorful visual effects by precisely mixing these chemicals. This process requires not only chemical knowledge but also artistic creativity.
What is the symbolic meaning of fireworks in different cultures?
- China: It symbolizes the exorcism of evil spirits, the celebration of the harvest and the arrival of the new year. Fireworks performances during the Spring Festival are a symbol of family reunion and festivity.

- Japan: The summer fireworks festival is not only a visual feast, but also a time for people to pray and give thanks, symbolizing hope and beauty.

How does the production of fireworks combine science and art?
Fireworks production is known as a precise art that requires a combination of chemical, physical and aesthetic principles. It may take weeks or even months to make a complex firework. Designers need to consider factors such as burning time, height, color and shape. Modern fireworks shows also incorporate computer technology to achieve precise firing programming and create breathtaking visual effects.
