| Abstract: |
A system and method for launching projectiles, such as fireworks projectiles, which explode in the air into a pyrotechnic display. The projectile includes a shell constructed from a binding agent and an explosive additive which explodes the shell into small particles. The explosive additive, which may be nitrocellulose, causes the exploded particles to be rapidly burned and consumed to form lightweight, inert flakes that fall harmlessly to the ground. The projectile is aimed and launched by a launcher to rapidly expel the projectile from a launching tube. Once in the air at a predetermined location in the sky, a fuse inside the projectile operates to detonate the projectile into its intended pyrotechnic display. The fuse is extremely accurate and enables detonation of the projectile at precise altitudes. An electronic control system controls launching and detonation of the projectiles in a precise and repeatable manner. The external geometry of the projectile also is configured so that the projectile tumbles when launched and follows a more predictable, repeatable and accurate path in flight.

We claim:
1. A fireworks projectile for exploding into an aerial pyrotechnic display, comprising:
- (a) an explosive charge connected to a detonating fuse, wherein the charge contains a composition adapted to explode into a pyrotechnic display upon ignition by the fuse;
- (b) a shell containing the explosive charge; and
- (c) a priming composition comprising a mixing agent and an explosive additive that are added to the shell to facilitate burning and consumption of the shell upon ignition of the explosive charge, wherein the mixing agent comprises acetone and the explosive additive comprises black powder.
