Electrical theory demonstrates that IF you are using an un-gapped metal accessory inserted into a wand that does not have a safety spark gap AND the internal wiring fails, there is a chance that there would be a subsequent draw on the line current. This could be a lethal occurrence. While this has not been documented (nor rumoured) to have happened in 70 years of violet wand history, there is still a chance it COULD happen if those circumstances occurred. It's safest to play with the glass electrodes, spark-gapped metal electrode accessories, or make sure your wand has an internal safety spark gap. If a spark gap is present in neither your wand nor your metal accessory, there is a slight increase in actual statistical risk that you should fully understand before making the choice to play with those circumstances. SSC players will stick to metal accessories that have a spark gap of some type..this can even be an air gap, the poor connections between ball chain links, or a resistant spacer. RACK proponents will understand the additional risk involved with ungapped metal accessories.
