A deception perpetrated by the movie industry that 12 volts DC does anything other that make sparks when making a direct short. Add a coil and capacitor, well that is a different story.

Don’t know if you remember the old crank telephones of the 40s and 50s. The crank turned a 48-volt generator. Not much current, but would definitely get your attention. Probably would work better than 12V.
