All that education, and none of your gung-ho experts or books had ever
considered the possibilities of a bit of news\tissue paper, a two minute
wait, a match or cigarette lighter and pairs of functioning eyes and ears.

polarise the solution and apply a voltage across it, so you could term this
`electrophorysis with thermally mediated sonic assessment.'
