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.

Provided is a party popper in which, inside of a cylindrical body having a discharge port at the front end, an explosive charge to be exploded by an operation of pulling a pull string and launchable objects arranged between the explosive charge and the discharge port are accommodated, and the discharge port of the cylindrical body is closed by a lid member that is push-opened by the launchable objects discharged toward the discharge port upon receiving a blast generated by explosion of the explosive charge.

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.

A Pyro-Cube fireworks includes a plurality of fireworks units. Each of the fireworks units includes a fuse, a plurality of fireworks launching tubes, at least one male tube, and at least one female tube. The fuse connects with the female tube. The male tube and the female tube are configured in a rim of the fireworks units. The fuse connects all fireworks launching tubes with the male tube from the female tube. The female tube of one fireworks unit engages with the male tube of another fireworks unit to connect the fuse of the female tube with the fuse of the male tube of adjacent fireworks unit. Only the fuse on the female tube of the first fireworks unit has to be ignited, and all fireworks units are ignited in a sequence corresponding to the connecting sequence of the fuses. The igniting operation of the fireworks is simple and safe.
