Wouldn't want to do that with a CW coil. There will be lots of current passing through your body, possibly damaging nerves and heating up all sorts of stuff inside you that shouldn't be heated up.

the best conductor in your body is your major bloodveins, even if the current would flow on the outside of those, I would never try it on purpose, in my job as an electrician I have been zapped too many times to ever take chances.
Once I had a 3 phased shortwiring directly in my hand from 3x 400VAC, knocked me unconscience for minutes and the scars to remind me. Use photoshop if you want images of yourself with streamers tbh.

I bellive there has been one person killed doing that stunt. A streamer from a TC left the top of his head and connected with something grounded in the room he was in. I would say don't do it.

Yeah, dont try it unless you absolutely know your TC isnt going to deliver more than 2ma into you. I'd say you could do it with a SGTC, but not a SSTC.

Skin effect in humans is a myth. Skin effect applies to perfect conductors, the human body of which is far from it. I believe Bert Hickman actually did the calculations but the skin depth in human flesh turned out to be several meters (i forgot the actual number)
So yes, all current you conduct with a SSTC is going through your body heating up nerves / tissue, and because your nerves aren't sensitive to that frequency, you feel no pain - but the damage is being done.
So in a nutshell . . . don't try this at home kids!

interesting, with mine 2000W coil (maybe it was 2500W or more, i don't remember) i take 50W electric bulb (wolfram thread ) and take on contact with metal pincers and in other contact go bright white spark from my coil , and in short time electric bulb was red color (not very bright) but just it go red, i get electric low frequency (i feel electricity in my body, so maybe it was low frequency,) kickback and i let go electric bulb but i don't get ground in to my body, just my capacity did it

I don't totally agree with the skin effect being a myth in humans. if it is truly cause significant amounts of damage you'd feel it. you might not feel the actual electricity but you would definitively feel the RF internal burns etc.
In my opinion if it looks dangerous it probably is so I wouldn't be doing this anyway. I'd rather do this with a SSTC than an SGTC if I had my choice. That 60Hz neon sign transformer would really worry me.

i really worry for MOT's, its 1A and 2KV, it's killing machine
