Pyrotechnics and Fireworks

Firstly, you should consider that a minor firework display will cost approx. between £4000 and £8000 pounds. A reasonable council run display on 5th November is likely to have around spent £20,000 on fireworks (plus more on other costs such as security). A large, full scale display will set you back well over £100,000. Therefore, assuming that each council has at least 1 display a year (multiply 160+ unitary councils @ £20,000 = £3.2 million) and there will be many minor events across the UK (perhaps 300 x £6000 = £1.8 million) and numerous large scale events such as New Year etc (e.g. 100 @ £100,000 = £10 million). Then the total cost spent on fireworks within the UK each year is around £15 million.

The imporntance means something that is a important position or sanding. Firewors are dangerous so the importance is that all laws have a different age groupe and soe children and adults both do them. They break the law. Some people do not have fireworks.

Copper compounds, such as copper chloride or copper sulfate, are often used in fireworks to produce a turquoise color when they are heated during the explosion. The presence of copper ions in these compounds leads to the emission of specific wavelengths of light that give fireworks their vibrant turquoise hue.

Fireworks are a type of pyrotechnics, like a subcategory. Definition of pyrotechnics: Mixtures of substances that produce noise, light, heat, smoke, or motion when ignited. When fire works are ignited, they create a combination of the above, so they are in the category of pyrotechnics.

Assuming that the box has at least one airway and the fireworks are not all on top of each other, it is very possible to light fireworks in a cardboard box. Just try to make sure that the cardboard box is outside, and that the box has nothing in it, like cobwebs or even water stains.

A according to this internet site http://www.fantasticfireworks.biz/site/templates/ff_template.php?id=1,

The first recorded display in England celebrated the wedding of Henry VII in 1487.

Both fireworks and neon signs produce colorful displays using a combination of gases that are excited by an electrical current to emit light. They both create visual spectacles that capture attention and are commonly used for celebration or commercial purposes.

The Odyssey fireworks display typically starts around 9 pm. It's always a good idea to check the event's official schedule for the most accurate and up-to-date information.

No, it is not safe for a 2-year-old to handle or be around fireworks due to the risk of injury from sparks, burns, or explosions. Fireworks should only be handled by adults who follow proper safety precautions.

The two most common machines in firework manufuring is the ball mill which grinds up chemicals to make them very fine and for making black powder. The other common firework machine is a star roller which rolls firework chemicals onto a core and makes stars which are the pretty colors you see when a arial shell explodes.

yes.. firework display is at 7.15pm on Saturday 1st November 2008

Fireworks are matter. Everything that is a solid, liquid, or gas is matter, and a firework is a solid. The explosion of a firework is not a solid, however. Fireworks' explosions are chemical reactions, where atoms are rearranged.

You can visit the website of the National Fire Protection Association (NFPA) for valuable information on fireworks safety. They provide guidelines and recommendations to ensure a safe and enjoyable fireworks experience.

Jehovah's Witnesses have very few 'hard-fast' rules. If you were to see a list of our "do's and don'ts" it would read similar to what is known as the 10 commandments, such as 'don't steal,' don't commit adultry,' etc. Most of the ideals that guide a typical JW are based on what we call "principles." Bible knwledge on certain matters guides what a JW will decide for themselves what they will do under certain conditions. On the matter of fireworks, this could be a situation where a JW will weigh matters to make a decision. There is nothing wrong with fireworks in themselves. In fact, a JW may even purchase fireworks to set them off on their own, provided that it is legal in the area in which they are. My wife and I are both Jehovah's Witnesses. She loves fireworks, I couldn't care less about them. It's a matter of preference. Most fireworks displays are done in celebration of a holiday that we do not celebrate, such as Fourth of July or New Years. If the JW in question feels that to observe the fireworks show is tantamount to engaging in the celebration, then he will likely make a decision based on his conscience not to see the fireworks show. However, if he feels that to do so would not be taking part in the celebration, then he may choose therwise. It boils down to his or her conscience or that of the parent if it is a Jehovah's Witness child.

methane+oxygen ---> heat energy+carbon dioxide

I think this is correct. Feel free to change it, if it is wrong!!

Fireworks are sold at specialized shops in the U.S.A, primarily around Independence Day and other holidays. Regulations on fireworks vary by state and locality, so availability and types of fireworks sold may differ. It is important to adhere to local laws and safety guidelines when using fireworks.

Fireworks typically involve a combustion reaction, where a fuel (such as gunpowder) rapidly reacts with an oxidizer (such as potassium nitrate) to produce heat, light, and gases like carbon dioxide and nitrogen. Different metal salts are added to produce the vibrant colors seen in fireworks.

Again, this is word for word the question on a charity find raising quiz sheet. It's one thing to use the internet to do research, but to get other people to answer the questions for you is truly pathetic.

The time difference is due to the differences in the speed of light and sound. Light travels near 300,000,000 meters/second where sound travels 343 meters/second. Light travels almost one million times faster than sound therefore it reaches you first.

Volatile compounds in the wood undergo combustion, or reaction with oxygen, forming H20 and CO2 gases. Because of the makeup of wood being mostly carbon-based compounds, this reaction leaves behind soot and charcoal.

Some common parts of fireworks include the shell (outer casing that contains the explosive material), fuse (ignites the fireworks), and stars (particles that create colored effects when ignited). Other components may include lift charges (propels the firework into the air) and a bursting charge (explodes the shell to release the effects).

In a house - Hydrogen. It gives off heat when burnt and has non-toxic products of combustion (water vapour). It doesn't damage the atmosphere when used as a fuel as no carbon dioxide is produced. Out of doors - carbon. Readily available. Non-toxic products of combustion.
