schematic for a butane flame mod, aka schematic for a butane flame mod, butane, flame, mod, and schem

New from KillCo! The do-it-yourself butane flame modification kit! Shoot and burn your friends OR enemies. Not approved for use in all states.

It tells you how to make a butane flame kit with the following components:
2 - piezoelectric ignition circuits
2 - liquid reservoir assemblies
1 - short steel pipe
Making this would take decent familiarity with craft and decent familiarity with brains.
In the upper right corner is a note: 'First discovered by Dr. Ilids.'

It weighs about 100 grams. It is a electromechanical schematic. You think it might fetch about $2 on the market.
