What term refers to a device containing multiple pyrotechnic effects that are ignited and dispersed by a lift charge into the air?

The term that describes a device containing multiple pyrotechnic effects that are ignited and dispersed by a lift charge into the air is "Mine." In the context of NFPA 1123, a mine is a specific type of aerial shell that typically launches multiple effects at once when it is ignited. The lift charge propels the mine into the air before it bursts, creating a visually impressive display with various pyrotechnic effects, such as colors, shapes, and sounds.

Understanding the definition of a mine helps differentiate it from other types of fireworks. For instance, a finale typically refers to the concluding portion of a fireworks display, often featuring a rapid succession of large aerial effects but is not a device itself. A ground display piece is a type of pyrotechnic device that remains on the ground rather than being launched, and a comet is usually a type of aerial effect that leaves a long burning trail. Therefore, the term “Mine” accurately fits the description given in the question.
