# The Science Behind Fireworks

*Fireworks are an incredible showcase of chemistry and physics. They consist of a shell packed with gunpowder and chemical compounds. When ignited, the explosion releases heat, light, and sound, creating the dazzling effects we see. The height and pattern of a firework are determined by its design. Stars inside the shell burst to form shapes like flowers or hearts. Advances in technology now allow for eco-friendly fireworks, reducing the environmental impact while maintaining their brilliance.
