Well, I don't know, The first coil i tried was wrapped around a paper towel 
tube(very primitive)but the output was not able to be felt. Same thing with 
the coil that i described in one of the first replies. When it is not tuned 
well and produces 2" sparks, you can easily touch it. It merely tingles, (my 
dad wants to know what effects it has on humans) and it gets a really wierd 
sensation after a little while. Then it gets HOT. Oh well, some of us 
teenagers never learn, and so much for "Predictable" TC's...    P.S., is 
ther anyone out there who has some 22 awg wire?...
