A method of converting conventional Class C fireworks having an explosive body portion and a safety fuse which extends therefrom into safer and louder firecrackers comprising the steps of: (A) forming a housing having a cylindrical side wall and first and second end portions of a size to completely receive the body portion of a conventional Class C firecracker therein so that an air space is created between the side walls of the cylindrical housing and the body portion of a conventional Class C firecracker, (B) inserting the conventional Class C firecracker within the cylindrical housing so as to be spaced inwardly of said side walls thereof and spaced inwardly of said end portions thereof and in such a manner that the safety fuse extends outwardly of said housing adjacent one end portion thereof, (C) closing the end portions of the cylindrical housing by inserting first and second material disks therein so as to firmly abut the conventional Class C firecracker and simultaneously engage the cylindrical side walls of said housing, (D) sealing the material disks to the cylindrical side walls of the housing by filling the end portions of said housing with a glue.
