| 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 using a compressed gas to rapidly expel the projectile from a launching tube. Once in the air at a predetermined location in the sky, an electronic 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.

We claim:
1. A system for creating a fireworks display, comprising:
- (a) a fireworks projectile designed to explode into a fireworks display in the air, the fireworks projectile comprising a shell containing an explosive charge, wherein the shell is constructed from a composition that includes an additive such that upon detonation of the charge the shell is exploded along with the charge into small particles that are rapidly burned and consumed;
- (b) an electronic fuse connected to the explosive charge in the fireworks projectile for detonating the explosive charge and exploding the fireworks projectile into the fireworks display in the air at a predetermined time period after launch; and
- (c) a launcher for launching the fireworks projectile into the air, in which a non-explosive launching medium comprising a compressed gas at a controlled pressure is used to propel the fireworks projectile from the launcher into the air.
