1,000,000-cracker "teepee" built at Western Winter Blast in 2006
A superstring, also known as a cracker wall, is a name commonly given to an immense bundle of firecrackers, usually numbering in the hundreds of thousands, which are often a central fixture at fireworks conventions. Although large compound strings of firecrackers have been constructed since firecrackers were invented, the superstring was greatly popularized by the Pyrotechnics Guild International, whose yearly convention often features a huge superstring consisting of well over a million firecrackers. Superstrings are usually constructed over a rudimentary wooden or metallic structure as a sort of curtain wall.
At the 1976 P.G.I. (Pyrotechnic Guild International) Convention in Grand Junction, Colorado, member Robert (Rob) Berk came up with the idea of connecting a series of firecracker strings together in order to make a "superstring". Fellow members Lino Nivolo, Rudy Schwerdt, and Bob Luke collaborated in the construction. The final count of this first attempt was approximately 2,000 firecrackers. The excitement of building this string increased the following year at the annual convention in St. Croix Falls, Wisconsin when the superstring exceeded the hundred-thousand mark. To add to the excitement, auctioneer Rob Berk pounded the gavel as Lou Czaplewski paid $25 for the right to light it. Over the years, the superstring has increased in size and the amount paid to light it has exceeded $4,000.
The largest superstring ever constructed was built by the Pyrotechnics Guild International in 2006. It was over 1,000 feet long and contained 10,500,000 firecrackers. It was ignited on August 11 and burned for about three minutes. It was ignited from both ends simultaneously and burned towards the center, which was raised into the air on a crane.
A flare, also sometimes called a fusée, fusee, or bengala in some Latin-speaking countries, is a type of pyrotechnic that produces a bright light or intense heat without an explosion. Flares are used for distress signaling, illumination, or defensive countermeasures in civilian and military applications. Flares may be ground pyrotechnics, projectile pyrotechnics, or parachute-suspended to provide maximum illumination time over a large area. Projectile pyrotechnics may be dropped from aircraft, fired from rocket or artillery, or deployed by flare guns or handheld percussive tubes.
Fireworks are a class of low explosive pyrotechnic devices used for aesthetic and entertainment purposes. The most common use of a firework is as part of a fireworks display, a display of the effects produced by firework devices.
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.
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 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.
Incendiary weapons, incendiary devices, incendiary munitions, or incendiary bombs are weapons designed to start fires or destroy sensitive equipment using fire, that use materials such as napalm, thermite, magnesium powder, chlorine trifluoride, or white phosphorus. Though colloquially often known as bombs, they are not explosives but in fact are designed to slow the process of chemical reactions and use ignition rather than detonation to start or maintain the reaction. Napalm for example, is petroleum especially thickened with certain chemicals into a 'gel' to slow, but not stop, combustion, releasing energy over a longer time than an explosive device. In the case of napalm, the gel adheres to surfaces and resists suppression.
A firecracker is a small explosive device primarily designed to produce a large amount of noise, especially in the form of a loud bang, usually for celebration or entertainment; any visual effect is incidental to this goal. They have fuses, and are wrapped in a heavy paper casing to contain the explosive compound. Firecrackers, along with fireworks, originated in China.
A sparkler is a type of hand-held firework that burns slowly while emitting bright, intense colored flames, sparks, and other effects.
In an explosive, pyrotechnic device, or military munition, a fuse is the part of the device that initiates function. In common usage, the word fuse is used indiscriminately. However, when being specific, the term fuse describes a simple pyrotechnic initiating device, like the cord on a firecracker whereas the term fuze is used when referring to a more sophisticated ignition device incorporating mechanical and/or electronic components, such as a proximity fuze for an M107 artillery shell, magnetic or acoustic fuze on a sea mine, spring-loaded grenade fuze, pencil detonator, or anti-handling device.
Flash powder is a pyrotechnic composition, a mixture of oxidizer and metallic fuel, which burns quickly and if confined produces a loud noise. It is widely used in theatrical pyrotechnics and fireworks and was once used for flashes in photography.
L'International des Feux Loto-Québec, also known as the Montreal Fireworks Festival, is the largest and most prestigious fireworks competition in the world. It has been held yearly in La Ronde over the Dolphins lake, since 1985, and is named after its main sponsor, Loto-Québec. It hosts an estimated 3 million spectators each year, with approximately 6,000 fireworks set off during each show. Each summer, eight or nine pyrotechnical companies from different countries present a 30-minute-long pyromusical show, competing for the Gold, Silver and Bronze Jupiters or trophies.
The Pyrotechnics Guild International or PGI founded in 1969 is an independent worldwide nonprofit organization of amateur and professional fireworks enthusiasts. Its membership is the largest pyrotechnic community in the world.
A Judas' belt, sometimes called Judah's belt, is a type of firecracker that produces multiple explosions. It is one of the most popular firecrackers in the Philippines during New Year's Eve celebrations.
Film budgeting refers to the process by which a line producer, unit production manager, or production accountant prepares a budget for a film production. This document, which could be over 130 pages long, is used to secure financing for and lead to pre-production and production of the film. Multiple drafts of the budget may be required to whittle down costs. A budget is typically divided into four sections: above the line, below the line, post-production, and other. The budget excludes film promotion and marketing, which is the responsibility of the film distributor. Film financing can be acquired from a private investor, sponsor, product placement, film studio, entertainment company, and/or out-of-pocket funds.
Consumer fireworks are fireworks sold for use by the general public. They are generally weaker in explosive power than the fireworks used in professional displays.
This is a list of worldwide fireworks competitions.
On the morning of December 31, 2007, ten fireworks stores began burning in Barangay Turo, Bocaue, Bulacan, Philippines, causing a series of explosions in the area. The fire lasted for almost an hour and caused several traffic jams in Fortunato F. Halili Avenue and the North Luzon Expressway.
M-80s are an American class of large powerful firecrackers, sometimes called salutes. M-80s were originally made in the mid 20th century for the U.S. military to simulate explosives or artillery fire; later, M-80s were manufactured as fireworks. Traditionally, M-80s were made from a small cardboard tube, often red, approximately 1+1⁄2 inches (3.8 cm) long and 9⁄16 inch (1.4 cm) inside diameter, with a fuse coming out of the side; this type of fuse is commonly known as cannon fuse or Visco fuse, after a company responsible for standardizing the product. The tubes usually hold approximately 3 grams of pyrotechnic flash powder. The "M" is designated by a U.S. military convention for "standard" equipment and "80" is for the 80 grains of flash powder within it.
Mexican handcrafted fireworks production is mostly concentrated in the State of Mexico in central Mexico. The self-declared fireworks capital of Mexico is Tultepec, just north of Mexico City. Although the main ingredient for fireworks, gunpowder, was brought by the conquistadors in the 16th century, fireworks became popular in Mexico in the 19th century. Today, it is Latin America’s second largest producer, almost entirely for domestic use, with products ranging from small firecrackers to large shells and frames for pyrotechnics called “castillos” (castles) and “toritos”. The industry is artisanal, with production concentrated in family-owned workshops and small factories with a number operating illegally. The relatively informal production and sales of fireworks have made it dangerous with a number of notable accidents in from the late 1990s to the present, despite attempts to safety regulations.
The National Pyrotechnic Festival, which takes place in Mexico, is an annual event to promote the country's tradition of production and use of fireworks. It began as celebration in honor of John of God, the patron saint of fireworks makers, in the municipality of Tultepec, State of Mexico, which produces about three quarters of all Mexico’s fireworks. The main event, a parade of "toritos" or bull-shaped frames with fireworks on them, began in the mid 19th century. The modern national festival began in 1989 and includes various events including fireworks competitions, but the main event remains that of the toritos, with about 250 "running" along the streets of Tultepec in 2013.
On 10 April 2016 at approximately 03:30 AM IST, the Puttingal Temple in Paravur, Kollam, Kerala, India, experienced an explosion and fire after firework celebrations went awry. As a result, 111 people were killed and more than 350 were injured, including some with severe burns. The temple and at least 150 houses in the area of the temple were damaged by the blast. According to local reports and eyewitnesses, the explosion and fire were caused by sparks from a firecracker being used in a competitive fireworks display igniting fireworks in a concrete storehouse. The temple did not have permission from Kerala government authorities to conduct a "competitive fireworks display". About 15,000 pilgrims were visiting the temple to mark local Hindu celebrations during the last day of a seven-day festival of the goddess Bhadrakali.
