My grandfather wired a Ford vibrating spark coil to a metal lamppost that the town drunk used to piss on every Saturday night, until................he lit up one night after the coil was turned on****************.
A friend used a Ford coil tied to his 49 Mercury chopped and channeled chassis. If someone leaned on the car, he turned the coil on after dropping a chain through the floor to complete the circuit.***********************************
A Ford coil was used to fire sparkplugs in the exhaust pipes that went up just behind the cab of another friends pickup. The sky lit up when they were fired.***************(probably not enough unburned fuel in today's cars to do the same, but i would lke to try
