SOURCES OF INSULATED WIRE Heavily insulated wire is available from some mail-order companies. Look for "high voltage" wire with ratings like 20KV or 50KV. If you cannot find a source, the next best thing is to use the center conductor of cable-TV cable, stripping off the black jacket and the copper braid. The center conductor will have a thick polyethelene or teflon insulation. Next best thing is "test lead wire," available in red and black colors from Radio Shack. Standard plastic-coated wire will usually work temporarily, but support it away from conductive objects such as tabletops. Another trick: give your wires a heavy insulation by sticking them through vinyl aquarium tubing.
