12vdc inverted and rectified\n\n\n\nthe positive is a ran through a water capasitor containing distilled water with no electrolite and a 10 plate ss setup +nnnnnnnnn-.\n\nThen - off the rectifier goes through another water capasitor containing distilled water with no electrolite and 2 ss plates. \n\n\ndifferent spacing of these plates give a different spark. maybe this could be acting as a varible capasitor,,,,,just a thought.
