What is the composition that propels a firework device into the air known as?

The composition that propels a firework device into the air is referred to as a Lift Charge. This is a crucial component in the construction and functionality of aerial fireworks, as it provides the necessary thrust to launch the device into the sky. The Lift Charge typically consists of a specially formulated explosive material that generates a significant amount of gas when ignited, pushing the firework upward.

Understanding the role of the Lift Charge is essential for anyone involved in the design, setup, or execution of a fireworks display, as it directly affects the altitude and trajectory of the fireworks once launched. Proper handling and knowledge of this component are vital for ensuring safety and effectiveness during a display.
