Introduction A firework is an incendiary device or material that can be used for signalling orentertainment. There are chemicals located in the nose of the rocket that explode, producing the colours seen. The art of fireworks, first originated in ancient China, with the first explosive being made from a mixture of black powder during the Sung dynasty. It is believed that the explosive mixture was created by a combination of sulfur, saltpeter and charcoal. The Chinese found that
Chemistry behind Fireworks Did you know that when you see a commercial fireworks display you are looking at chemistry in action. You may have asked yourself “I wonder what is going on to make all those pretty colors and patterns” It is controlled chaos!! I tell you. Let us break this down to the basic we will start with a typical shell. Starting at the bottom we have a lifting charge which contains good ole black powder. The lifting charge gets the party started by creating an explosion
All year round, fireworks illuminate the night sky with countless spectacular effects in displays taking place worldwide. “People everywhere enjoy the fantastic explosions and the brilliant light displays of fireworks” (Www.Wisc.edu). Fireworks are used in many celebrations around the world. When fireworks first came into Europe they were only used for special events, such as the arrival of a king or queen from the capital or another country. “However, these spectacles are much more than just a form
The Science behind Fireworks Fireworks have been around for centuries. The chemistry and physics that are used in the making of fireworks has become very well rounded. Most people are unaware of how much science is used in this process. As spectators at a firework show we know a fuse is lit, we hear a loud boom, a whizzing sound as the mortar flies up into the sky, explodes, lighting up the sky with brilliant colors. So what happens when the firework explodes? What causes such vibrant colors?

FIREWORKS There is a lot of physics and chemistry involved in making fireworks. Their colors come from the different temperatures of hot, glowing metals and from the light emitted by burning chemical compounds. Chemical reactions propel them and burst them into special shapes. Here's an element-by-element look at what is involved in your average firework: Aluminum - Aluminum is used to produce silver and white flames and sparks. It is a common component of sparklers. Antimony - Antimony is
Chemical Reactions: Section 2 Chemical reactions do not just occur in a chemistry classroom; they are constantly taking place everywhere. It may be a simple or even complex reaction. For example, a simple chemical reaction that takes place in our everyday life is cooking. When food is heated, it undergoes three main changes: appearance, structure, and flavor. This is due to the chemical reactions going on inside of the food. Different methods of cooking generate different reactions as they happen
Honors Chemistry 1. History of Fireworks Red, Blue, and Orange. These are just few of the colors seen in many different fireworks. These wonderful explosions have been going on for thousands of years all dating back to the tenth century china where it originated from first. Fireworks are a part of Chinas culture and eventually this spread to other countries. The largest manufacturer and exporter of fireworks in the world is China. Fireworks can either be performed on the ground or air by a
Survey of the Sciences Unit 4: The Science of Fireworks 7-7-14/7-14-14 What is a firework? An explosive or combustible used for display. In the 19th century the introduction of new ingredients such as magnesium and aluminum greatly heightened the brilliance of such displays. There are two main classes of fireworks, force-and-spark and flame. In force and spark compositions, potassium nitrate, sulfur, and finely ground charcoal are used, with additional ingredients that produce various types
discovery. Johan Arfwedson passed away in 1841 at his estate in Sweden. Sodium Sodium was discovered in 1807 by Sir Humphry Bartholomew Davy. Davy was born in 1778 in England. He was originally apprenticed as a surgeon, but instead took up chemistry in the pharmacy. Many of his early experiments took place in the home of his grandfather John Tonkin. Davy is best known for his research in the field of electrochemistry 1/6 Alkali Metals- Group 1 (IA) and his discovery and isolation
