Large fireworks are explosive devices designed to create spectacular visual displays in the sky. They typically consist of a shell filled with gunpowder and various chemical compounds that produce vibrant colors when ignited. These fireworks are often used during celebrations such as New Year's Eve, Independence Day, and other festive events. When launched, large fireworks ascend into the air before bursting into dazzling patterns. The explosion creates a loud sound, which adds to the excitement of the display. Safety measures are essential when handling large fireworks, as they can be dangerous if not used properly.
