Abstract
Pyrotechnic fireworks launch apparatus is provided. The apparatus includes a base to which is affixed a male-configured launching cylinder adapted to accept thereover, in combination, an internally cylindrical, female-configured projectile, wherein the projectile has a proximal and a distal end thereof. The projectile houses a fused pyrotechnic display charge proximate its distal end and also houses a fused launching charge encased therein and partitioned from the display charge. On insertion of the launching cylinder into the proximal end of the projectile, thereby mounting the projectile upon the launching cylinder, the encased launching charge and the launching cylinder are in abutting relationship. Upon ignition of the fused launch charge, the projectile is launched vertically from the launching cylinder. The external configuration of the projectile may have any number of shapes. In a preferred configuration, it is shaped as a rocket.
