Such displays are the focal point of many cultural and religious Celebration (party), celebrations, though mismanagement could lead to List of fireworks accidents and incidents, fireworks accidents. Fireworks take many forms to produce four primary effects: noise, light, smoke, and floating materials (confetti most notably). They may be designed to burn with colored flames and sparks including red, orange, yellow, green, blue, purple and silver. They are generally classified by where they perform, either 'ground' or 'aerial'.

Pyrotechnics
Pyrotechnics is the science and craft of creating fireworks, but also includes safety matches, oxygen candles, Pyrotechnic fastener, explosive bolts (and other fasteners), parts of automotive airbags, as well as gas-pressure blasting in mining, quarrying, and demolition. This trade relies upon self-contained and self-sustained exothermic chemical reactions to make heat, light, gas, smoke and/or sound. The name etymology, comes from the Greek words ''pyr'' (πυρ; 'fire') and ''technikós'' (τεχνικός; 'artistic'). Improper use of pyrotechnics could lead to List of pyrotechnic incidents, pyrotechnic accidents. People responsible for the safe storage, handling, and functioning of pyrotechnic devices are known as pyrotechnicians. Proximate pyrotechnics Explosions, flashes, smoke, flames, fireworks and other pyrotechnic-driven effects used in the entertainment industry are referred to as proximate pyrotechnics. Proximate refers to the pyrotechnic device's location relative to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Skyrocket
A skyrocket, also known as a rocket, is a type of firework that uses a solid-fuel rocket to rise quickly into the sky; a bottle rocket is a small skyrocket. At the apex of its ascent, it is usual for a variety of effects (stars, bangs, crackles, etc.) to be emitted. Skyrockets use various stabilisation techniques to ensure the flight follows a predictable course, often a long stick attached to the side of the motor, but also including spin-stabilisation or fins. These rockets have been made at least since the early decades of the 20th century, and in many countries, including Japan and China. The older type of bottle rocket was typically a black powder skyrocket with an engine about 2 inches (5 cm) long and up to 0.375-inch (9-mm) diameter, mounted on a thin bamboo splint and often having a small report charge. Modern bottle rockets are small and very cheap. They are often sold by the box (but more commonly by the pack, or by the gross, a packet of 144 rockets) for ...

Explosive
An explosive (or explosive material) is a reactive substance that contains a great amount of potential energy that can produce an explosion if released suddenly, usually accompanied by the production of light, heat, sound, and pressure. An explosive charge is a measured quantity of explosive material, which may either be composed solely of one ingredient or be a mixture containing at least two substances. The potential energy stored in an explosive material may, for example, be: * chemical energy, such as nitroglycerin or grain dust * pressurized gas, such as a gas cylinder, aerosol can, or boiling liquid expanding vapor explosion * nuclear energy, such as in the fissile isotopes uranium-235 and plutonium-239 Explosive materials may be categorized by the speed at which they expand. Materials that detonate (the front of the chemical reaction moves faster through the material than the speed of sound) are said to be "high explosives" and materials that deflagrate ar ...

Pyrotechnic Stars
Pyrotechnic stars are pellets of pyrotechnic composition which may contain metal powders, salts or other compounds that, when ignited, burn a certain color or make a certain spark effect. They are a part of all projectile-type fireworks. The most common is the aerial shell. When watching this firework, it will launch into the sky, burning a lifting charge. Once the shell has attained proper altitude, due to other mechanisms within the firework, it will ignite the stars. Procedure Stars are either rolled, pumped or cut. *Rolled stars are small cores of a hard material (often lead shot or an organic material such as mustard seeds or even cut stars) which are coated in a rotating mixer similar to a concrete mixer. First, water is sprayed on these cores. Then an amount of a pyrotechnic composition is placed into the mixer. As these two steps are repeated, the stars grow into a larger spherical A sphere (from Ancient Greek, Greek , ) is a surface (mathematics), surface anal ...

Port Jackson
Port Jackson, commonly known as Sydney Harbour, is a natural harbour on the east coast of Australia, around which Sydney was built. It consists of the waters of Sydney Harbour, Middle Harbour, North Harbour and the Lane Cove and Parramatta Rivers. The harbour is an inlet of the Tasman Sea (part of the South Pacific Ocean). It is the location of significant landmarks such as the Sydney Opera House and Sydney Harbour Bridge.
