An igniter device (10) operable to remediate a floating oil spill in a body of water is provided. The device (10) comprises a pyrotechnic device (28) that is actuated through an actuator assembly (20) comprising time delay circuitry (24). Upon actuation, the time delay circuitry (24) begins a countdown permitting the device (10) to be safely deployed from an aerial vehicle. The pyrotechnic device (28) ignites a fuel source (38), which in turn ignites the floating oil spill.

Disclosed herein are pyrophoric composite materials comprising nanoporous pyrophoric alpha iron nanoparticles dispersed in a ceramic matrix for use as aerial decoys. The composite material is prepared using tape casting methods to produce a thin film. The iron precursor in the film is then activated by reduction under a hydrogen atmosphere. The composite nanoporous pyrophoric alpha iron nanoparticles and ceramic material is an improvement over current pyrophoric decoys as it eliminates the use of harmful chemicals and the need for a substrate to support the composite.

Disclosed is a kind of combination fireworks, in which a plurality of paper tubes form a tube row, and the plurality of tube rows are stacked and assembled for forming, wherein each tube row is provided with a bottom cardboard, two sides of the bottom cardboard are correspondingly provided with notch positioning holes, and the bottom cardboard beside the notch positioning holes forms the protruding cardboard beside the holes; the cardboard beside the holes is folded and stuck on both sides of the paper tube, and both ends of the paper tube are respectively embedded in corresponding notch positioning holes. The structure of spaced tube rows is adopted, so that the radial size error of the tube body of the paper tube is not accumulated in the tube rows, thus allowing the tube body to accurately reach a predetermined work position, and improving the accuracy and reliability of subsequent processes.

A Cold Spark Device (CSD) is provided and includes a CSD base, wherein the CSD base includes a CSD collector defining a collector cavity, wherein the CSD collector includes a collector top, collector sides and a collector bottom, the collector top defining a top opening, and wherein the collector bottom defines a first collector bottom opening and a second collector bottom opening, a CSD sparkling device, and a CSD display case, wherein the CSD base includes a base structure which defines a base cavity for containing the CSD sparkling device, wherein the base structure defines a base cavity opening communicated with the base cavity.

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.
