The Confligationator

A man’s walking cane built on a recycled 20 ga. shotgun barrel.  The contents consist of a highly flammable binary concoction that, when mixed in a reaction chamber and ignited, combusts with an intense heat, its expansion causing the flame to erupt from from the nozzle at the head of the cane with significant force and range.  The chambers within the cane hold sufficient volume for half a dozen seconds of pyrotechnics.  This has been patented by the United States Patent Office, 1877.
