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 modular pyrotechnic launch unit includes a launch module, a first module, and a second module. The launch module includes a launch barrel. The first module is coupled in series to the launch module. The first module includes a first ignition state in which the first module ignites a pyrotechnic element that will then pass through the launch barrel. The first module also includes a first pass-through state in which the first module allows a pyrotechnic element ignited by another module to pass through the first module. The second module is coupled in series to the first module. The second module includes a second ignition state in which the second module ignites a pyrotechnic element that will then pass through the first module and through the launch barrel.
