Care was taken but as expected the salt water pool will have an extremely low E field in it and is just like a big ground. The chain mail glove also has a separate copper braid extending down towards my feet just in case I brought my hand out too far. There was no sensation at all at any time.
People do have negative connotations about electricity and water some of which was taught to us by our mother's. So we have this uneasiness about the two together.
Nevertheless the circuit paths are clear and dont involve me.

You didn't put salt in your swimming pool did you?

Woah! That is a pretty fat arc!

I hope some kid with mots doesn't try to duplicate what you're doing here.

I have a 4 MOT supply running this under oil but it was not pushed at all. No, kiddies, don't do this at home (like much of the stuff on 4HV). No-one seems to have been interested in replicating any of this stuff anyway.

And the salt in the pool? Salt water is used for two reasons. It is closer to isotonic with human extracellular tissue fluid (not sure how close) so it doesn't sting your eyes. Sea water is about 5 times isotonic if I recall. Chlorination is achieved by simple electrolysis with a titanium cell.

A light bulb used as a plasma globe? wink an AC flyback, ignition coil, or a plasma globe driver.

Correct on the subject of the picture, as for the power...It was my very weak SSTC running at 12v.

For those who celebrate Easter and those that don't...

What happens next to this chocolate Easter bunny (a highly commercialised Australian custom).

Ohhhhh, I'd never guess. Near instantaneous destruction by pulsed discharge followed by combustion of aluminium foil and steel wool? Or maybe it will get Z-pinched and form a chocolate black hole. Can I have an ear if I can find one intact? tongue
