How Do Fireworks Work?

Fireworks have different compartments. First there is the aerial shell, and this has the different types of powered metals, such as lithium carbonate, copper (I) chloride, calcium chloride, and etc. Also different metals will affect the colour of the firework.  Second the lifting shell, it’s attached to the bottom of the aerial shell, and this helps launch the firework by the compressed air. Third, the fuse is the wire that is hanging outside of the tube/ casing, and it’s connected to the around the base of the lifting shell. After, it will be placed into a tube, and it’s ready to be launched. The fireworks will be propelled into the air and later explode in a suitable distance away from the people.
