Display
fireworks can trace their origin back to the Chinese long before
gunpowder was invented. Some think that the original display fireworks
consisted of chunks of bamboo thrown into a hot fire. When heated the
bamboo which stores sap and air explodes making a loud noise. Later on
in Chinese history, alchemist discovered gunpowder. When this
gunpowder was inserted into a shoot of bamboo and thrown into the fire
a very loud bang was the result. This is considered the first
firecracker.
Later on in the history of display fireworks other chemicals were
added to produce different effects. For example, by adding strontium a
red color was produced. Green was produced by adding barium, and
copper produced blue. The Italians are given credit for these
improvements in display fireworks and people throughout the ages have
enjoyed their efforts.
Today display fireworks can be purchased in a variety of colors,
sizes, and strengths. You can purchase shells, rockets or repeating
aerial displays, or what is known as cakes. Cakes have a long duration
and are very popular in home display fireworks. Shells are also
popular because they explode high in the air much like professional
display fireworks.
Regardless of what type of display fireworks you purchase make sure
that they are legal in your state or county and that you follow all
safety rules and precautions. A complete map of state display
