Design news latest “Gadget Freak” shows you how to make your own Tesla coil plasma gun -

Here’s a gun that can light up an unplugged fluorescent bulb or spark electrical storms in an unplugged incandescent bulb — the same effect as a plaza globe. Richard Morrow of Cheshire, England, built the Tesla Coil plasma gun using the casing of an inexpensive cordless hand drill. He uses the trigger of the hand drill as the plasma gun’s trigger. The device is powered by a 12V battery. The high frequency, high voltage from the gun causes the argon gas in light bulbs to become ionized, which creates streamers that are attracted to the fingers holding the bulb.
