Cat-007 [Big Boss Cuts] Take-5 <~>
Cat-007 [Big Boss Cuts] Take-5 <~> Fireworks... It is unclear exactly how the mixture of saltpetre, sulphur, and charcoal was discovered to make what we know today as gunpowder. However, we do know that flying fireworks have been around for centuries. It is also certain, based on the popularity of these explosives, that setting off fireworks is really good fun.
Rocket type: Rockets are actually powered by an internal engine. The rocket type of firework has more in common with a mortar shell than it does with a space rocket. These fly through the air when ignited. They sometimes carry parachutes, stars4, or big bangs when they reach the peak of their flight.
Roman candles: These long tubes shoot compact balls of chemicals from one end, creating a series of flaming stars. Inside the tubes, the chemical balls are packed one on top of the other, with layers of sawdust between them.
Fountains: These are cone-shaped and sit on the ground. A hole in the top allows gases to escape, shooting coloured sparks into the air.
Sparklers: These are long pieces of wire. Half of the length of the wire is covered in chemicals that give off bright sparkles of light when lit. The sparks burn off at 1650°F. Sparklers are credited with causing some of the most serious firework accidents.
Aerial shells: These are the kings of fireworks. The most spectacular visually, and usually the loudest. These are the ones the professionals use. These are launched the same way military mortar shells are launched. After placing the shell into a skyward facing tube, an external fuse is lit. The explosion of the lift charge inside the tube then launches the shell...
