Different elements and compounds burn in different colours. By carefully arranging the substances in fireworks gives a spectacular multi-coloured display.
The legality of fireworks varies with the type of fireworks, the state, and local or county laws. Here in California, "Safe and Sane" fireworks can be legally sold for two weeks before Independence Day. However, some counties and cities are banning them this year due to the extreme wildfire danger caused by our 5-year drought.
Propagation rate of burn exceeds the speed of sound ... i.e. it's a sonic boom.

If it's a straight one, you secure it in some dirt, light the fuse and stand back about 25 feet.

The scheduled day for Independence Day fireworks will depend upon your location. For 2016, some places set them off July 2, others on July 3, and yet others on July 4. The scheduled time is usually around dusk - 9pm or 9:30pm. Check your local media for locations and times.

The Chinese invented fireworks. They use them to celebrate all sorts of things. In the old days, it was believed that evil spirits roamed the earth on the last night of the year, and the fireworks scared them away so you could start the New Year without any evil.
Firework was invented by ancient Chinese
Yellow usually comes from sodium while gold coloration usually comes from iron. There are several possibilities, but sodium lines dominate all the rest.
The Chinese invented gunpowder and when Marco Polo left China he brought gunpowder back with him. Soon the Europeans figured out how to make it. The introduction of gunpowder changed the world and how people fought wars. With the addition of gunpowder wooden Mott and Bailey castles had to change to stone. Armor no longer protected people and cannons could sink ships and knock walls down. The first guns were made and the first political… Read More
I think so:)
Carnivals and circuses fit into the category of traveling shows. They begin with the letter C.
The addition and combination of various powdered metals and minerals added in various combinations produce the colors that we see. Copper, magnesium, iron powders, sulphurs , and many other elements all combine to create the palette of colors pyrotechnical artist's employ for our pleasure. Copper is used to make the blue colour of fireworks. Although copper produces a green flame in a laboratory flame test, the use of copper in relatively low temperature flames and… Read More
The brilliant colors you see when the fireworks explodes comes from a wide variety of metal salts that are packed inside the firework. Now, when most people think of salt they're thinking of the white crystals they sprinkle on their food. That is a salt, but it's not the only salt. That's sodium chloride (NaCl). A salt is any metal atom bound to a non-metal atom. In the case of table salt, sodium is the… Read More
Their ions (produced by the burning of the fireworks) emit a wide variety of different colors of light.
Fireworks that are set off are a chemical change.
A certain material in the fire work gives it the color when it explodes into miny pieces.😃
That's a pretty wild dream. Perhaps the fireworks and unidentifiable person are significant of someone important coming into your life or your sister's life in the near future.
Dealers pay low(wholesale) prices at a public auction, private might be better. A lot depends on the car and the markey for it in your area.
This entirely depends on where you live. Even county to county regulations vary, so you best contact the local fire marshalls office to get a definite answer answer 2 In some states, it is illegal for a private citizen to light fireworks at any time. A special license is given for a municipality to have a fireworks show.
All fireworks, even Safe and Sane are illegal in New York State.
Fireworks combine art and science. And you should NEVER EVER attempt to make your own unless you *really* know what you are doing. The colors in fireworks come largely from different metals in the fireworks which when heated glow different colors for different elements (this same effect is used to test for elements in something called the flame test). See the Related Links for "Chemistry of Firework Colors" to the bottom for the answer.
The largest firework ever produced was Universe I Part II, exploded for the Lake Toya Festival, Hokkaido, Japan on 15 Jul 1988. The 1,543 pound shell was 54.7 inches in diameter and burst to a diameter of 3,937 feet. Note: This was not an aerial shell but a shell that was placed on a floating platform and ignited.

Fireworks were invented because a Chinese cook spilled the ingredients of gunpowder into his cooking, he found that the chemical burned very hotly and made loud explosions. The Chinese soon put this crude gunpowder into sticks of bamboo, and when thrown into a fire it exploded making a large flame and a loud noise.
Fireworks Fee: It depends on what kind of fireworks show you are talking about - a show for the town... or a box in the backyard? A 15-minute show for family and friends - which will include some fountains and cakes and artillery shells - will cost approximately $500 to $1,000.

This is what Wikipedia has to say: The earliest unequivocal documentation of fireworks dates back to 12th century China, where they were first used to frighten away evil spirits with their loud sound ("bian pao") and also to pray for happiness and prosperity. Eventually, the art and science of firework making developed into an independent profession of its own. In ancient China, pyrotechnicians (firework-masters) were well-respected for their knowledge and skill to mount dazzling displays… Read More

Fireworks tubes are made by rolling thick paper tightly around a former, such as a dowel. Though they can be made by hand, most firework/tube factories use machinery to manufacture tubes. Whenever tubes are used in fireworks, at least one end is always plugged with clay to keep both chemicals and burning gases from escaping through that end. The tooling is always made of non-sparking materials such as aluminum or brass. Clay is inserted into… Read More

they are actually considered exothermic change because they release energy.
To burn something requires oxidation (usually with O2 in the case of combustion).. therefore 'burning' is a chemical reaction with oxygen (O2)... Fuel + Oxygen (in air) --> carbon dioxide + water (The above works in most cases, obviously sulfur [for e.g.] would give SO2 and no water) H3CCH2CH3 (g) + 5 O2 (g)--> 3 CO2 (g) + 4 H2O(l) Propane + Oxygen --> Carbon Dioxide + Water In the case of fire works the… Read More

The stars (pretty colored balls) are arranged in the shell in the desired shape. It's just that simple.
Any explosion will generally happen symmetrically. When it's on the ground, the ground stops the "bottom" part and you only see the top part. An explosion with an extreme amount of heat, such as a nuclear explosion in the atmosphere will also be influenced by the "heat rises" factor.

when a cardboard container filled with pyrotechnic material that has been launched into the air explodes ------------- A break is the portion of an aerial shell that sits above the launch charge. It is ignited by a timed fuse to go off at it's maximum altitude. There are an abundance of types of breaks such as star-bursts, scramble comets, brocade, etc. A multi-break shell has two or more color bursts when launched~Chaz
