Exploding fireworks happen when a several chemical reactions take place one after the next. The addition of heat to the fireworks causes the firework to be activated that triggers a chemical reaction. When the chemical compounds which are contained inside the firework burn with oxygen they change into other gases such as carbon monoxide, nitrogen and carbon dioxide, as smoke which comes from the fumes from fireworks.
What Makes Fireworks to explode in different colours?
The colors are produced by an use of salts of iron in fireworks. Metal salts that are commonly used in fireworks include: strontium carbonate (red fireworks), calcium chloride (orange fireworks), sodium nitrate (yellow fireworks), barium chloride (green fireworks) and copper chloride (the blue fireworks). The most common type of fireworks is purple. They are made using a mixture of strontium (red) and copper (blue)
When a firework is lit the firework is then launched into the air by a lift charge. It’s all black, explosive powder in a tight space that when ignited produces rapid heating and gas increase that can send a firework as high as 1,500 meters (300 metres) into the sky.
What Are The Physics of Fireworks?
The solid compounds compressed into the cardboard packaging don’t necessarily rearrange themselves to form other compounds. Most of the energy that is stored in them is transformed into four forms of energy (light thermal energy, sound and heat).
In accordance with the fundamental law of physics, known as energy conservation (one of the most crucial and fundamental scientific rules that govern about how the universe functions) the chemical energy contained in the fireworks prior to it igniting must be exactly the same as the cumulative remaining in it after the explosion has occurred, plus the energy emitted as sound, heat, and light.
In addition, Physics also demonstrates why a firework springs into the air. Its charge is not much more than that of a missile. When it explodes, in similar fashion to the space rocket or jet engine the firework is triggered by action-and-reaction (this is also called Newton’s Third Law of motion). When the powder melts inside the charge, it gives off hot exhaust gases that fire backwards. The energy that is generated by combustion gases that are fired backwards is just like the blast produced by of a rocket engine. It generates an opposing “reactive” force that shoots the firework , sending it in the air.
If you take a look at the different pictures of the fireworks that are featured on this page you’ll see another piece of fascinating physics taking place in the background. Notice how fireworks create color-coordinated blasts? If there’s a part of the firework that’s left, the other part will go to the right. It’s rare to see a firework with all stars going to the left or more blasts on the left than to the right. the blast is still perfect.
Why does this happen? It’s due to a fundamental law of physics , called momentum conservation.
The firework’s energy must be identical prior to, during ignition and after an explosion, explosions must be accurately offset by the correct explosion.
A Few of the Best Fireworks for Beginning Fireworkers
If you’re new to the idea of launching your own fireworks thing , then it’s a good idea to do your first firework experiments with smaller fireworks, like catherine wheels and repeaters. Here are a few of our top fireworks for beginners:
Angel Dust Fireworks
Fireworks made of angel dust, when illuminated, shoot out thousands of jaw dropping stars. They are also relatively quiet , so they are great if have noisy neighbors.
If you’re looking to enjoy some amazing fireworks, but don’t want to risk setting up rockets and then launching them, it’s a good idea to look into barrage packs. They can be lit and left, and they’ll rise one after the next, providing you with a fantastic lighting show.
“Strike A rose” firework
This stunningly quiet display of a firework creates an amazing lighting show that requires minimal effort for the person who is using it. Simply set it up, flick the fuse , and then enjoy the spectacle! It’s a fireworks show with an effect called a crossette. It’s similar to a star which splits into four stars with a cross shape.
