Does not generate 400 thousand volts. Takes 75 Thousand volts to jump an inch therefore 400 Thousand volts shoud jump 5.3 inches.My experience wih product was voltage created a apark between the two meta

It's cool but the largest spark I've gotten out of it is maybe 4". That argues for a max voltage of 100,000. At best half of their stated rating.Also, the drive belt broke the second time I got it out for a demo. When I took it apart and found the broken piece, it looked more like an O-ring than a drive belt. Must've been designed from a former Morton-Thiokol employee. If you're gonna do that, at least throw in a few spares.
