A fireworks aerial display shell is provided with multiple casings of cylindrical configuration that are joined together in end-to-end relationship. Each casing defines an interior volume in which an effects charge is packed. A plug is positioned between the effects charges and has an opening through which an ignition source passes to ignite one of the effects charges as a result of burning of another of the effects charges. An outer casing may surround at least parts of the multiple cylindrical casings and includes multiple partially ball-shaped segments.

A fireworks aerial display shell is provided with lift charges positioned at opposite ends of a casing that additionally contains an effects charge. Fuses are operatively associated with the lift charges and the effects charge in a manner to ignite the lift charges a period of time before igniting the effects charge. When either one of the ends of the casing is placed facing a closed bottom of a launch tube of a reusable mortar, the burning lift charge at that end of the casing when ignited exerts a propelling force to propel the aerial display shell upwardly out of the launch tube to an intended height before the effects charge is ignited to create a pyrotechnic visual effects display.

An improved, multiple-use fireworks launcher (10) is provided for the launching of fireworks such as an artillery shell (40) having a lower lift charge (42) and an upper effect charge (44). The launcher (10) includes a base (12), with an upstanding, open-top launch tube (14) operably coupled with the base (12). A reinforcing section (16) is positioned about the lower end of launch tube (14), and preferably comprises a tubular sleeve (36) tightly secured to the outer surface (32) of launch tube (14). The combined thickness of the tube (14) and section (16) are sufficient to prevent catastrophic failure of the launcher (10) in the event a shell (40) is improperly placed within the tube (14) in an inverted condition with the lift charge (42) thereof positioned over the effect charge (44).
