Fireworks are a class of low explosive pyrotechnic devices used for aesthetic and entertainment purposes. The most common use of a firework is as part of a fireworks display, a display of the effects produced by firework devices. Fireworks competitions are also regularly held at a number of places.
A mine (aka. pot à feu) is a ground firework that expels stars and/or other garnitures into the sky. Shot from a mortar like a shell, a mine consists of a canister with the lift charge on the bottom with the effects placed on top. Mines can project small reports, serpents, small shells, as well as just stars. Although mines up to 12 inches in diameter appear on occasion, they are usually between 3 and 5 inches in diameter.
