US Patent 5,756,920 Special effect flame cannon

Abstract
A flame cannon for producing an explosion, the cannon including a tank, an effect valve, a nozzle and an ignitor, the tank coupled to a carbon dioxide source and a propane source, the tank and sources used to pressurize liquid propane therein. The nozzle forms a substantially linear and non-atomizing channel. When the effect valve between the tank and nozzle is opened, the pressurized liquid propane is forced through the nozzle and forms a liquid propane column thereabove which begins to disburse into the atmosphere wherein it is ignited to form a mushroom-shaped explosion.

When my brain itches I scratch it at the patent office.
