A "Fire Rocket" is a type of pyrotechnic device designed to produce a bright display of light and sound. It typically consists of a cylindrical body filled with combustible materials that ignite and propel the rocket into the air. Fire rockets are often used in celebrations, such as New Year's Eve or Fourth of July festivities, to create colorful explosions in the night sky. These rockets operate on the principle of thrust, where the combustion of fuel generates gases that push the rocket upward. Fire rockets can vary in size and complexity, with some designed for professional displays and others for personal use. Safety precautions are essential when handling and launching fire rockets to prevent accidents.
