A consumer-ready, disposable pyrotechnic display system includes a pyrotechnic module and a control module. The pyrotechnic module includes a mounting substrate, electrically ignitable pyrotechnic devices, and electrical conductors connected to the pyrotechnic devices and disposed beneath the mounting substrate. The control module includes a housing having an upper surface and a bottom surface on which electrical contacts are disposed; and a processor, a memory, a power supply, and a transceiver within the housing. The electrical conductors are connected to the electrical contacts prior to receipt by the consumer. When the transceiver receives a signal from a remote device (such as a cellular telephone), the processor ignites each of the electrical conductors in a sequence programmed into the memory of the control module.

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.

A firecracker and firecracker arrangement. The firecracker includes an outer sheath having two face sides and that is closed at both face sides with a layer of barrier material. Pyrotechnic effect elements and a bursting charge are arranged inside the outer sheath. A first ignition line that penetrates the barrier material is guided up to the bursting charge. The bursting charge is accommodated inside a completely closed, cylindrical jacket that is arranged coaxial to the outer sheath such that a longitudinal center axes of the outer sheath and of the cylindrical jacket coincide. The first ignition line is guided through an opening in the cylindrical jacket to the bursting charge. The pyrotechnic effect elements are arranged to form a predefined geometric shape in at least one plane extending transverse to the longitudinal center axis of the outer sheath.
