Hi all,

Anyone got any high-current/low-voltage horror stories they'd care to
share? You know; where your messin' about with a car battery or

Though there is considerable voltage involved in the production of the
currents involved, it is the (forces of the magnetic field of the)
current that crushes the coins.
