Fireworks are explosive pyrotechnic devices that are used for entertainment and display purposes. They produce vibrant displays of light, color, and sound through the combustion of various chemicals. Fireworks are typically launched into the air and consist of a combination of explosives, color-producing agents, and other special effects. They are often used to celebrate special events and occasions, such as Independence Day or New Year's Eve, and are admired for their dazzling visual effects and the excitement they bring to spectators.
