A rocket in its simplest form. F
the nose of the rocket explode to produce colors, while the shape of the
firework depends upon the construction of the firework’s shell and the
arrangement of the exploding stars
History of Fireworks
You might be wondering who invented fireworks >. It is believed that the first natural "firecrackers" were bamboo stalks
that when thrown in a fire, would explode with a bang because of the
overheating of the hollow air pockets in the bamboo. It’s thought that the
first fireworks were used in China more than 2,000 years ago. They were
used in religious ceremonies and to celebrate New Year. The Chinese
believed these natural "firecrackers" would ward off evil spirits.

In big displays, fireworks are put inside metal tubes or launch tubes. These
stay on the ground, while the rocket flies to the sky.
2. Fuse
Fuse paper contains chemicals that burn steadily, allowing time for a person
to stand back after lighting. This is the part that starts the main part of
the firework burning and ignites other, smaller fuses that make the
interesting, colorful parts of the firework explode some time later.
3. Propellant
Inside the cardboard case, gunpowder burns quickly to shoot the rocket
skyward. It's usually made up of tightly packed, coarse explosive
gunpowder also known as black powder.
4. Gun powder
Explosive gunpowder is stored in a chamber inside the firework., which is
responsible for the loud sound and the spread of stars.
5. Stars
The gunpowder is mixed with stars. Stars are the chemical mixtures that make a
firework’s flashes of color.
Firework patterns
Manufacturers also use multi-break shells that have different compartments
inside them, often with stars of various colors and compositions. When these
are placed and fused in a specific order, they will explode in sequence to
create recognizable patterns and shapes in the sky.

Ring shell - a bright, expanding ring of stars.
Palm trees
- stars move up as a “trunk,” then spread out as “branches.”
- a pattern that leaves long trails of stars.
Serpentine - many
stars that zigzag outward as they fall
Fish - a swarm of stars
moving randomly across the sky
Willow - in this, star trails fall
nearly all the way to the ground.
How fireworks get their colors?
Fireworks contain metallic salts which then make fireworks produce
different colors.
Purple is made from
strontium salts
and copper.
Red comes from
lithium salts
Orange >flashes are created by calcium salts.
>Green >lights are made using barium compounds.
>Blue >flashes come from copper compounds.
How Hi-tech Modern Firework displays work?
Firework displays that you often see on TV on big events are often run by
computers. The computer sends an electric spark down a wire to light each
fuse. It makes fireworks launch in the right order and explode at their
highest points in the sky.
