I can't be bothered to look it up, but he said he got something like 20k ohms across the electrodes, one in each hand. The clips were hooked up to one end of the can, so there must have been SOME contact between the hands and the end. Along the join/edge maybe, that runs along the length of the can?

I find this discussion fascinating from an exterior point of view.
The original cans were steel with Galvanization on them.
With some level of corrosion on them (evidence the pictures of cans in Ebay ads) which would cause some variance between PCs.
The Ohm readings from those would be higher than bare Aluminum cans, until the Aluminum oxidized.
I recall that there was some general rule about the cans getting too old.
Also, the fact that the sweat of the hands would cause some metal from the Galvanization to be removed onto the hands (washed my hands after session a few times).
Galvanization is a Zinc plating process if I remember correctly.
That thought causes me to wonder about the poison effects of too much Zinc absorption.
I seem to recall that Hubbard's cans in all the pictures were brand new with no corrosion.
Did he really get better results?
