Fireworks

Fireworks are devices that produce visual and audible effects through controlled chemical reactions. Typically used for celebrations and events, they consist of a shell filled with explosive materials, colored powders, and metal salts that create vibrant colors. When ignited, the shell explodes at a certain height, releasing the materials to form patterns and shapes in the sky. Fireworks have origins in ancient China and have evolved into a popular form of entertainment worldwide, often associated with holidays, festivals, and public displays. Safety precautions are essential, as they can be dangerous if not handled properly.
