Answer 2

Not sure if this is EXACTLY what you are looking for, but what the hey?

A firework is classified as a low explosive pyrotechnic device used primarily for aesthetic and entertainment purposes. The most common use of a firework is as part of a fireworks display.

Fireworks (devices) take many forms to produce the four primary effects: noise, light, smoke, and floating materials (confetti for example). They may be designed to burn with colored flames and sparks. Displays are common throughout the world and are the focal point of many different cultural and religious celebrations.

Fireworks were originally invented by the Chinese, for entertainment purposes, as a natural extension of the Chinese invention of gunpowder. In China, they were first made by firework masters who were well-respected for their knowledge of the many complex techniques used to create truly dazzling firework displays. Such important events and festivities as New Year's and the Mid-Autumn Moon Festival were and still are times when fireworks are guaranteed sights.

Fireworks are generally classified as to where they perform, either as a ground or aerial firework. In the latter case they may provide their own propulsion (skyrocket) or be shot into the air by a mortar (aerial shell).

The most common feature of fireworks is a paper or pasteboard tube or casing filled with the combustible material, often pyrotechnic stars. A number of these tubes or cases are often combined so as to make, when kindled, a great variety of sparkling shapes, often variously colored. The skyrocket is a common form of firework, although the first skyrockets were used in war. The aerial shell, however, is the backbone of today's commercial aerial display, and a smaller version for consumer use is known as the festival ball in the United States. Such rocket technology has also been used for the delivery of mail by rocket and is used as propoulsion for most model rockets.

Improper use of fireworks may be dangerous, both to the person operating them (risks of burns and wounds) and to bystanders; in addition, they may start a fire if landing on flammable material. For this reason, the use of fireworks is generally legally restricted. In the United States, fireworks are classified as either consumer or display fireworks based upon the amount of pyrotechnic composition an item contains. Display fireworks are restricted by law for use by professionals. Consumer items are available to the public and are smaller versions containing limited amounts of material to reduce potential dangers.

Answer 3

maximum fireworks comprise 4 aspects: a field, "stars" that are pellets of cloth that produce colorations and spark at the same time as ignited, a "bursting charge" or explosive, and the fuse which guarantees that the firework gained't ignite till it is reached the proper altitude. The "stars" are prepared in a particular progression to create the shape, and explosives are positioned interior them to cause them to boost outward. colorations are produced by technique of the diverse chemical substances used contained in the fireworks. in a lot of cases they're metallic salts that produce diverse colored flames at the same time as they burn. (Sodium nitrate burns yellow, copper chloride burns blue, etc.) As for the sounds, the "crackling" sound you listen is small quantities of gunpowder or black powder. those that "sizzle" are aluminum or iron fillings burning. those that "scream" or "whistle" as they upward push have cardboard tubes packed with gas and open on one end, and at the same time as the carbon dioxide rushes out this small area, it makes a whistling sound.

Answer 4

Well when a firework is made they get a stick and fill it full of chemicals which make them different colors, so when a firework is lit they zoom up and like spurt out different colors. Hope that helps u! =]

Answer 5

Different metals and chemicals. For example Magnesium burns bright white, copper, blue. Not sure about the others. Science was never my best subject.

Answer 6

I am sure you have seen in your Physics lab experiments that different materials burn with different colours.

Answer 8

I believe I have your solution to your problem. One of my friends is the actual creator of the firework (he is chinese). So he taught me all about fireworks. Fireworks sometimes do have color in them, this is usually because they put the color into them. It's very simple. My Chinese friend explained it to me, and after all he did invent the firework so I feel safe in his judgement on this. Hope that answered your question.

Answer 9

Various chemiicals and metals.. Copper, iron, magnesium and so on ..

Answer 10

chemicals : specifacly "salts" that are compositions of metals and halogene like , cobalt-chloride
