The Tesla Coil

The tesla coil is a super geek's science project.  But, it is a similar type of electrical coil configuration that runs a violet wand.  Tesla coils have much, much higher voltage and the primary and secondary is reversed over a violet wand's electrical coils.  Not portable, though small kit sizes are available.

Not to be messed with.  They can cause death unless you know what you're doing, and it takes a -LOT- to know what you are doing with them. 

 Verdict:  Leave it to the geeks.
