• Long sparks between a VDG dome and a sphere will not occur when a roofing nail is placed on one of them.
  • Other "lightning rods", such as a thumbtack, work to a lesser extent.
  • Use the wand between domes to discharge the VDG.

        (Plug into dedicated outlet to avoid tripping circuit breaker)
        (Keep VDG away from smart cart, computers and microphones)
