Very original device! I'd love to see some specs or plans on this contraption! I think it would be an awsome addition to a Fireworks Display Show!!

Well, the concept of a "Pyrophone" can be traced back to the 1700s. Think of it as a Steam Whistle. Only this one is internal combustion(If it's made like the old Pyrophones).
