Exploding fireworks happen when a series of chemical reactions occur one after the other. In addition, adding heat to the explosive triggers the firework that initiates a chemical reaction. Once the solid chemical compounds which are contained inside the firework are ignited by oxygen they transform into gasses such as carbon monoxide nitrogen, and carbon dioxide as smoke which is a result of the combustion gases from the fireworks.
What are the reasons why Fireworks explode with different colours?
The colours are created by using metals within the fireworks. The most commonly used metal salts in fireworks include: strontium carbonate (red fireworks) and calcium chloride (orange fireworks), sodium thermitrate (yellow fireworks) as well as 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, it is pushed into the skies by a lifting charge. This is all black and explosive in a confined space that is ignited and causes an explosive heat and gas surge that can create a fireworks that can reach up to 1,500 feet (300 metres) in the air.
What Are The Physics of Fireworks?
The solid compounds compressed into the cardboard packaging don’t necessarily reorganize themselves into other substances: the majority of the energy stored in them transforms into four other forms energy (light thermal energy, and sound).
According to the fundamental law of physics known as energy conservation (one of the most significant and fundamental scientific principles that regulate the way that the universe operates), the cumulative chemical energy contained in the fireworks prior to its ignition should be the same as the total remaining after the explosion has occurred, along with the energy that is released in the form of the sound, heat and light.
Additionally, Physics also demonstrates why fireworks shoot up into the air. The energy is no more than the charge of the missile. When it explodes, in much the same way as space rockets or jet engine it is powered by reaction-and-action (this is also called Newton’s Third Law of motion). When the powder ignites within the charge, it gives off gasses that are hot and emitted backwards. The energy that is generated by combustion gases that are fired backwards is similar to the blast that comes out from a rocket engine. It creates an counter-reactive “reactive” force that shoots the fireworks up, and then flies up into the sky.
If you take a look at the different pictures of the fireworks that are featured on this page you can see another bit of fascinating physics happening too. Do you notice how fireworks always produce uniform blasts of colour? If there’s one part of the fireworks going left, the other one will go right. It’s not common to see firework sending all the stars to the left, or greater numbers of blasts to the left instead of to the right. the blast is still symmetrically perfect.
Why is that? It’s due to another fundamental law of physics known as momentum conservation.
The firework’s energy should be equal before, during ignition and after an explosion. The explosions have to be precisely offset by right explosion.
Some of The Best Fireworks for Beginning Fireworkers
If you’re brand new to the all-in-one firework launch idea, it’s an excellent idea to begin your first experiments with smaller fireworks, like catherine wheels and repeaters. Here’s a few of our most popular fireworks for beginners.
Angel Dust Fireworks
The Angel Dust fireworks when ignited, explode with thousands of jaw dropping stars, they are relatively silent, which is great if you have fussy neighbours.
If you’re in the market for stunning fireworks but don’t want to risk setting up and launching rockets, you should consider barrage packs. THey can be lit and left and they will climb one after the other providing you with a fantastic illumination show.
“Strike A rose” firework
This quiet and eerie spectacle of firework produces an amazing light show with minimal effort for the person who is using it. Simply set it up, flick the fuse and watch the show! It’s a fireworks show with the effect of a crossette. It’s similar to a star which splits into four more stars, forming a cross shape.
