hello malcom,

interestingly i have observed the same type of pre- breakout phenomena with
my large 
wimshurst machine, if i open the gap to a bit longer than it can jump with
two leyden jar 
capacitors, charge it up and then touch one terminal i can see a globe of
beautiful 
feathery 'sparks' that extend for around 6 - 7 inches around the other
terminal, i have no 
idea how this occurs, i can only presume by suddenly grounding one side of
the device 
the other winds up at a huge potential relative to ground, it is really
wierd being a dc 
phenomena as well as an ac one - maybee same effec, different reason. i
would be very 
interested if anyone could proffer an explaination

intruigedly
