How do fireworks work? How do they make different colors and patterns?
In: 33
Fireworks are made of explosives and fuel. The fuel is usually a powder or liquid that burns very quickly. The explosive is a chemical that makes the fuel burn even faster.
When the fireworks are set off, the explosive sets off the fuel. The fuel burns very quickly and produces a lot of gas. The gas expands very quickly and makes a loud noise.
The different colors are made by adding different chemicals to the fuel. The chemicals make the gas glow different colors.
The patterns are made by putting the fireworks into tubes. The tubes are different shapes and sizes. The different shapes make the fireworks go off in different ways.
