Firework
Fireworks are a class of low explosive pyrotechnic devices used for aesthetic and entertainment purposes. They are most commonly used in fireworks displays (also called a fireworks show or pyrotechnics), combining a large number of devices in an outdoor setting. Such displays are the focal point of many cultural and religious celebrations. 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'. Aerial fireworks may have their own propulsion (skyrocket) or be shot into the air by a mortar ( aerial shell). Most fireworks consist of a paper or pasteboard tube or casing filled with the combustible material, often pyrotechnic stars. A number of these tubes or cases may be combined so as to make when kind ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sydney New Year's Eve
Sydney New Year's Eve is an annual New Year's Eve fireworks event in Sydney, Australia. The event currently consists of two fireworks shows, with an evening display known as the "Family Fireworks" held at 9:00 p.m. AEST, and the main "Midnight Fireworks" held at 12:00 a.m. Fireworks are launched from barges in Port Jackson, as well as nearby landmarks such as the Sydney Opera House, and the Sydney Harbour Bridge—which serves as the main focal point of the show via lighting and pyrotechnic effects. As one of the first major cities to celebrate the New Year, the event is widely-viewed in Australia and worldwide. Organizers have estimated the annual in-person attendance of the event to be around 1.5 to 1.6 million, with tourists accounting for a large portion of its attendees. Some locations, such as the Royal Botanic Garden, host ticketed seating areas. The event is usually organized by the city; as of 2020, the state of New South Wales was given "temporary custodianship" of ...

Pyrotechnics
Pyrotechnics is the science and craft of creating such things as fireworks, safety matches, oxygen candles, 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 comes from the Greek words ''pyr'' ("fire") and ''tekhnikos'' ("made by art"). 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 an audience. In the majority of jurisdictions, special training and licensing must be obtained from local authorities to legally prepare and use proximate ...

Skyrocket
A skyrocket 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, China, and Macao. 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 less than US$0.20 e ...

Collecchio
Collecchio (Parmigiano: ) is a town in the province of Parma, Emilia-Romagna, northern Italy. It is located by road southwest of the centre of Parma. A major food-producing area, it is home to multinational Italian dairy and food corporation Parmalat and the Parma F.C. training complex, Centro Sportivo di Collecchio, and is connected by railway. Under the Romans the town was called Sustrina, Later, in Christian times it was called, Colliculum, because of its location on a small hill. In 2015, Collecchio became recognized as the first community to mandate that all fireworks set off in the town be silent. History The first signs of human settlement in Collecchio date from the Paleolithic Age. With growing numbers of inhabitants in the Neolithic, deforestation led to flooding in the plains. As a result, settlements were moved up into the hills. The Roman road Clodia Segunda linking Parma and Luni (via Fornovo) and the Cisa Pass was a mainstay for the local economy and for the ...

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 some water is sprayed on cores. Then an amount of a pyrotechnic composition is dropped into the mixer. These two steps are repeated, and the stars will grow bigger and bigger into a spherical A sphere () is a geometrical object that is a three-dimensional ...

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 BLEVE * 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 are said to be "low explosives". Explosives may al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
