I wouldnt take anything that the so called "myth busters" peddle as gosple truth. Everything they do is a dilluted dumbed down version, and an insult to anyone with a functioning brain... There are a lot of other ways to approach this with an AC current... I'm going to start experimenting on this personally, at the moment I need to purchase supplies, but it's going to take a while, first step is aquiring a function generator, (that's going to be the expensive part)... Next I will have to construct an apparatus, I'm thinking about going with a water tube design using stainless steel 3/8 in tubing, and transparent pvc pipe... I should have a working device here in the next 3 weeks or so... I'll keep the thread posted on my findings.
