The "director" wants our help with the timing mechanism that detonates the fireworks and he's also worried about the safety of the spectators.
Aluminium is used to produce silver and white flames and sparks. It is a common component of sparklers. Ba Barium is used to create green colors in fireworks, and it can also help stabilize other volatile elements.
C Carbon is one of the main components of black powder, which is used as a propellent in fireworks. Carbon provides the fuel for a firework. Common forms include carbon black, sugar, or starch. Ca Calcium is used to deepen firework colors. Calcium salts produce orange fireworks.
Cl Chlorine is an important component of many oxidizers in fireworks. Several of the metal salts that produce colors contain chlorine. Cs Caesium compounds help to oxidize firework mixtures. Caesium compounds produce an indigo color in fireworks.
Cu Copper compounds produce blue colors in fireworks. Fe Iron is used to produce sparks. The heat of the metal determines the color of the sparks.
K Potassium compounds help to oxidize firework mixtures. Potassium nitratepotassium chlorateand potassium perchlorate are all important oxidizers. The potassium content can impart a violet color to the sparks. Li Lithium is a metal that is used to impart a red color to fireworks.
Lithium carbonatein particular, is a common colorant.
The Boise Fire Department says they want fireworks vendors to know that if an illegal firework sold from their stand causes a fire, they will be held responsible.

Mg Magnesium burns a very bright white, so it is used to add white sparks or improve the overall brilliance of a firework. Na Sodium imparts a gold or yellow color to fireworks, however, the color is often so bright that it frequently masks other, less intense colors.
O Fireworks include oxidizers, which are substances that produce oxygen in order for burning to occur. The oxidizers are usually nitrates, chlorates, or perchlorates.Worse, fireworks-associated air pollution can lead to medical problems in people with pre-existing lung and heart conditions.
Fireworks and Air Quality Several environmental researchers have studied air quality following fireworks displays, at . Many of us enjoyed watching spectacular fireworks displays to usher in the new year.
However, the vibrant colours of fireworks belie the effects that they can have on the environment. With this graphic, we take a look at some of the issues that they can cause. To an onlooker, it seems as if.
Fireworks CS6 does not display 4-byte characters in the document tab’s title on Windows XP. As a workaround, name the titles with ASCII or 2-byte Chinese characters. On Windows XP and Vista, some 2-byte and all 4-byte characters aren't correctly pasted to Illustrator when you use the Copy Path Outlines feature in Fireworks.
Fireworks competitions are also regularly held at a number of places. Fireworks 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 including red, orange, yellow, green, blue, purple, and silver.
Fireworks on the Fourth of July dramatically increase air pollution, boosting exposure to potentially dangerous pollutants for millions of onlookers, according to a recent study in the journal. Fireworks are responsible for thousands of fires and injuries each year. Fireworks by the numbers Fireworks start an average of 18, fires per year, including 1, structure fires, vehicle fires, and 16, outside and other fires.
