Using an estim to electrify a copper pipe

Hi,

I'm hoping someone will be able to help me as I'm stuck. I had some copper pipe from an actual DIY project and decided to try and re-create some of my favourite porn by attaching the copper to a frame so I could adjust how high the pipe was so it meant the sub is on tip toes with the pipe between his or her legs not quiet touching and then send electricity through the pipe so when the sub slightly lowers themselves then thier cunt or cock/bollocks get zapped.

I thought that was simple enough and I thought for the electricity I could just attach my e-stim via square pads to the rod but you can't feel the current at all however close I put the two pads

Is the estim the wrong device? How can I get the pipe up to a zapping level whilst still being safe? Should I make a better electrode?

Any help would be much appreciated

Only ONE pad should be attached to the pipe. The other to the persons body. When the pipe and body touch, the circuit will be completed.

How can you get the zapping level up? Start at ZERO and increase gradually.

Try it on yourself first.

The other thing is to use different kinds of electricity. I'd prefer using a violet wand for this. You don't need a circuit, just touch the copper when the bottom is on the horse.

You could soder a connection to it if so inclined, but do need to complete the circuit
