I read somewhere that you can test ignition wires for leaks by moving a "grounded" screwdriver over your wires in the dark. If there is a leak, then there will be an arc of electricity jumping from the wires to the screwdriver and down the grounded wire.

Has anyone ever tried this? And is a "grounded" screwdriver something that you can buy at an automotive/tool store, or is it something that you need to make from scratch?
