aerial shell

An aerial shell is a type of fireworks that is designed to explode in the air, creating visual effects such as colorful bursts and patterns. These shells are typically launched from mortars, which are tubes that provide the force needed to send them high into the sky. Once at a certain altitude, the shell ignites and releases its pyrotechnic materials, resulting in a display of light and color. Aerial shells are commonly used in professional fireworks shows and are popular for their dramatic impact and ability to cover large areas of the sky.
