History of Fireworks
Although no one is for certain when fireworks actually were created, experts do know that they were developed in ancient China, during the Han dynasty (about 200 B.C.) long before the rest of the world had any knowledge of them.
The Chinese developed two of the major components in fireworks. They invented paper and the substance which causes the explosions, gunpowder. However, gunpowder was developed long before guns or combustible firearms were developed.
• Only buy fireworks marked BS 7114.• Don’t drink alcohol if setting off fireworks.• Keep fireworks in a closed box. • Follow the instructions on each firework.• Light at arm's length, using a punk.• Stand well back.
• Never go near a firework that has been lit. Even if it hasn’t gone off, it could still explode.• Never put fireworks in your pocket or throw them.• Always supervise children around fireworks.• Light sparklers one at a time and wear gloves.• Never give sparklers to a child under five.• Keep pets indoors.
Black powder is one of the most dangerous explosives because it ignites easily by heat, friction, or spark.
In 2005, almost half of injuries caused by fireworks were to children under 18.
The art of firework creating
Light NOT produced from heat
Electron of atom or molecule absorbs energy, becoming unstable
Photons (light) released when electron returns to lower energy state. Photon’s energy determines its wavelength (color)
Gunpowder: 75% potassium nitrate, 15% charcoal or sugar, 10% sulfur
Component in gunpowder react when heat is applied (lighting the fuse)
Charcoal or sugar is the fuel
Potassium nitrate is the oxidizer
Sulfur moderates reaction
Fuel: charcoal and sulfur
Binder (holds mixture together): sugar or starch
Mix in water, forming a slurry that can be coated on wire or poured into a tube
Once dry…BAM!! You have a sparkler
Fuel and oxidizer are proportioned so it burns slowly for several minutes of fun!
A tube containing gunpowder is lit with a fuse
Gunpowder is used to propel firework in the air
A hole at bottom of firework lets expanding N and CO2 launch into sky
Packing of gunpowder, more oxidizer, and colorants determines shape
