ABSTRACT:
A firecracker construction includes a relatively small firecracker mounted within an enlarged supplemental housing so that an elongated fuse projects outwardly. Except for a portion of the projecting fuse, the smaller firecracker within the housing is completely surrounded by a solid, noncombustible material which enhances the report of the exploding firecracker.
Preferably the construction includes a U.S. Department of Transportation Hazard Class 1.4G explosive. Other preferred forms include a safety fuse. In particularly preferred forms, the noncombustible material is formed of clay, calcium sulfate, or a mixture thereof.
