Hi all,
    I've heard that they do the same thing with a figure 8
shaped coil and induce currents in the brain.. supposedly
causing halucinations.. I have no idea what kind of
currents or energies are involved.. Some kid here at the
university wanted to try it with my 5400J can crusher.. I
told him he was crazy!
