Pyrotechnics and Fireworks

light is frequency as our eyes detect the frequency spectrum of colors white is the brightest that we can see. Of course black is just the absence of light

Yes fireworks can kill you fireworks can also cause burns and scars and death and blindness and loss of hearing alsoThe big danger is that you can start a fire that will get out of control. This can certainly kill people.

why not !!

Transition metals are used to make fireworks because they can produce a variety of vibrant colors when heated. Each transition metal ion emits a characteristic color when it releases energy in the form of light. By incorporating different transition metals into the fireworks composition, a wide range of colors can be achieved, creating visually stunning displays. Additionally, transition metals are often used because they are relatively stable and safe to handle in pyrotechnic applications.

I actuall wrote a paper on this subject for my college English class and I learned that some people don't like them because they disturb their pets and wake them up. They also believe they are extremely dangerous which is not true when they are used properly, which often they aren't. The fireworks that cause the most injuries are bottle rockets and sparklers. The reason there are so many sparkler injuries is because a lot of people let their kids play with them. I guess they don't realize they burn at about 1,800 degrees.

because it will be very strong the flame k

china at the moment but idnia is catching up.

Worldwide, millions of fireworks are produced and launched every year.

In storage, they can last indefinitely provided they are kept dry and cool. In use, a firework may last anywhere from a second to a minute.

Fireworks use solid oxidizers within the chemical makeup of the charge. The chemical oxidizer fulfills the need for both oxygen and fuel in the fire equation. All that is needed is heat. Or just the surronding air.

The answer for 2007 is not a straight "yes" or "no." The City of Westminster has a very good and informative web site, although sometimes it takes some hunting to find what you're looking for. It may be too late for this question's asker for this year - here's the link though:

the cheaper firecrackers are in china but you can find it in your country in firecrackers stores... I recommend not to buy it on Internet, the service is good but it is very expensive (3 or 4 times higher than in stores)

A chemical change is one where new compounds or atoms (products) are being formed from other compounds/atoms (reactants). Fireworks involve combustion, which is a type of chemical reaction because the reactants are being changed into different products.

NOTE: don't mistake this for a nuclear reaction, all chemical reactions have the same number of each element on each side, but many form elements in their pure form (such as Hydrogen) from a reactant like H2O.

I believe the term is "pyrotechny." Hope this helps!

Thomas Jefferson (who wrote that the Declaration of Independence in 1776) said that the date should be celebrated with fireworks. So I would think fireworks were first used in July 4 1776 or so after the first Independence day.

The Illuminatios Fireworks are at 9pm every night.

However according to the Disney website; Epcot park closes at 9pm on common nights.
