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.

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.
