A "banger" is a type of firework known for its loud noise and explosive effect. Typically cylindrical in shape, bangers are designed to produce a sharp bang when ignited. They are often used in celebrations, such as New Year's Eve or Independence Day, to create excitement and mark special occasions. Bangers can vary in size and power, with some being small enough for personal use and others designed for larger displays. Safety is important when using bangers, as they can pose risks if not handled properly. Always follow local regulations and guidelines when using fireworks.
