How Fireworks Work
Fireworks have been around for several centuries now and have become a symbol of celebration. Whether it is New Year’s Day, in amusement parks, or any other kind of event, fireworks are known to create their own magic up in the sky.
But one wonders how does this magic really happen? How are fireworks able to make intricate displays within the sky once they get lit up? What goes into making a firework? All of these questions will be answered within this article. Written below is the list of the components that make up a firework and details on how each component is essential to how a firework operates.
Different Components Of A Firework
Generally, one firework consists of about five different components that make up a basic firework rocket. These components are listed below in further details:
- The Tail Or Stick
A long plastic or wooden stick is attached to the bottom side of a firework. This component is known as the tail or the stick. It is responsible for making the firework shoot in a straight line so it does not start flying in a random direction and cause chaos! Plus, it also helps in positioning the firework effects with precision and accuracy.
- The Fuse
The fuse is what starts the main component of the firework, which is ‘the charge.’ It burns and ignites the other smaller fuses that are responsible for making the colorful parts of the firework explode once it’s up in the sky. The fuses get lit by the electrical contacts that are called wirebridge fuseheads in a public firework display. Hence, once the firework technician presses a button, there’s an electric current that ends up flowing through the wire and into the fusehead, causing it to briefly burn so that the main fuse gets ignited. This is much safer than manual ignition since it can be done from a distance.
- The Charge Or Motor
This component is made to blast the firework up into the sky. There are times when it makes the firework travel to great heights, as high as 1000ft at the speed of almost several hundred miles hour, which is as fast as your typical jet fighter! Most of the time, this component consists of coarse and tightly packed explosive gunpowder, which is also called the black powder. The charge is only responsible for sending the firework up into the sky and it does not make the remarkable explosions that everyone sees.
- The Effect
The is the component that’s responsible for creating that amazing display up in the sky once the firework is high in the air. One firework can either come with one effect or several other effects that are packed into different compartments. These effects fire off in a sequence and are ignited by a time-delay fuse that burns slowly and works its way upward and gets ignited by the firework’s main fuse. There is a difference between the effects and the main charge, even though both are explosives. Each single effect is usually made up of a much finer and loosely packed explosive material that’s arranged into separate star-like shapes and they make the smaller colorful explosions from a bigger firework.
- The Head
This component is the top part of a firework and it contains the effect (or effects). The head can either have a pointed cone-like shape or a blunt end. The cone-like shape makes the firework go faster and makes it more aerodynamic, which improves its chances of going in a straight line.
