Summer festivals are not only fun for all the foods they’re providing and the activities they’re offering, but also because of their well-anticipated fireworks. Those orchestrated explosions are so grandiose that most can’t help but feel moved by the spectacle. Some may even start wondering what makes those magical displays, and I am for sure one of them. Most of my knowledge about fireworks came from school, where one of my teachers told us about the many components: Oxidizers, fuel, colouring salts and a binding agent.
