How do you make fireworks ?

If you’ve found this article you’ve most likely experienced the joy of watching fireworks displays and are wondering about the science behind making your own fireworks at home. Truth is, it’s very easy to make your own fireworks. Every tutorial on this website, and every firework has a few basic components:

  1. Every firework should have a fuse
  2. A chemical propellant will accelerate the reaction
  3. The components that make up an effect / reaction at the end.

Both aerial and ground fireworks will have a fuse and some sort of propellant. Once the fuse is lit and the flames reach the propellant chemicals, a reaction among various other materials such as aluminum, steel, zinc or magnesium will create different effects such as a spark, bang or report.

The size and shape of the firework can change the effect as well. Bottle rockets are typically narrow and have a small hole which emits enough sparks to thrust the rocket into the air. If there was not a hole in the case it would end up exploding since all the energy would build up.

Some of the most fascinating fireworks involve more complex recipes.

Mortars are some of the most spectacular fireworks and often have multiple stages. Each section can have different chemical mixtures that cause different effects.
