Fireworks come in different forms, with each type having different features and characteristics. There are many different types of fireworks, including fish, stars, flares, and aerial patterns. In this article, we will cover the different types, as well as safety precautions. Read on to learn about fireworks! Listed below are the different types and the chemical reactions they go through. Read on to learn how they work and why fireworks are so dangerous. And remember to always keep a safe distance!
Explanation of chemical reactions in fireworks
Fireworks are colourful explosions caused by chemical reactions between metal salts and oxygen. The heat generated by the firecrackers causes the atoms to be excited to higher energy states, where they relax and emit light in the specific wavelength. Different metals produce different colours. For example, sodium glows red, copper burns orange and strontium emits green. By mixing and matching metal salts, we can produce all sorts of other colours, which is called painting in the fireworks industry.
Elements used in fireworks
In a typical fireworks show, the most important element is carbon. Carbon forms the black powder that launches the fireworks into the sky. Its properties are important as carbon can also be found in many other substances, such as diamond. A diamond is made of four atoms surrounding each other, while a graphite firework is composed of two layered layers of covalent bonds. Each of these substances has a unique chemical structure, allowing the explosion to occur with varying colours.
Types of fireworks
There are several types of fireworks. One type of aerial effect is the crossette, a firecracker-like bursting device that shoots out stars. The word crossette comes from the French, and refers to the diminutive form of the word crosse. The other types include sparklers, rockets, cakes, and snakes. The term salute refers to anything that explodes, and this type of firework is most often used for aerial effects. Another type of aerial effect is the peony, which is a combination of two common firework types.
Safety precautions
When observing a celebration, use caution when handling fireworks. Young children should never handle them, and adults should always wear protective eyewear and gloves. Always keep a bucket of water nearby. It is also essential to wear safety eyewear and to protect your ears. Never relight dud fireworks. Instead, soak them in water before discarding them. Do not turn around after shooting a dud. Never aim fireworks at your eyes.
Pollution caused by pyrotechnic devices
The use of fireworks can cause significant air pollution, especially on Fourth of July. According to the World Health Organization, PM2.5 levels can rise more than three times the normal level on July 4. That’s the same amount of smoke produced by a moderate wildfire. This pollution affects people in many different ways. It’s also more dangerous for vulnerable populations, such as children and the elderly. If you’re planning to light fireworks this Fourth of July, take these steps to keep the pollution down.
