What is an Aerial Shell?

An aerial shell is a specific type of firework that is designed to be launched into the air, where it then ascends to a predetermined altitude before bursting. This aerial display creates a variety of visual effects that are typically experienced in public fireworks shows. The key characteristic of an aerial shell is its capability to launch from a mortar or similar device, reaching a height that allows for a more spectacular light show as it bursts open, releasing colorful sparks and patterns against the night sky.

In contrast, other options mention fireworks that either remain on the ground or are related to the sales process or safety measures, which do not capture the essence of what defines an aerial shell. Thus, understanding the functional design and purpose of aerial shells is essential for anyone involved in the planning or execution of fireworks displays, as they play a critical role in achieving the desired visual impact that audiences expect during such events.
