Jim,

Terry is quite correct. For shrinking coins or exploding wires
it requires multiple kilo-joule discharges to do it reliably and
this can present some serious dangers to an unwary experi-
menter, both from an electrical and a mechanical perspective.
Anyone contemplating taking on a quarter shrinker/exploding
wire/water arc explosion/rail gun project(s)or any project
requiring large capacitor discharges should read the safety
section of Bert Hickman's website BEFORE starting!
