Screamer fireworks are made by combining a metal powder, typically aluminum or magnesium, with a suitable oxidizer and a binder. The mixture is shaped into a small projectile, often with a fuse attached, and then encased in a casing that allows for the sound to resonate. When ignited, the rapid combustion of the metal powder and oxidizer creates loud, shrill sounds as the gas expands and escapes through the casing. The design and material choices influence the pitch and duration of the scream produced.
