I used a plastic container, and the electricity doesn't travel through. That would be the same as using enameled container. So if electricity doesn't travel, how does it work? Does it work? Do you need to get electricity to travel through the container?
If I put one finger inside the positive wire in the pan and another finger for negative wire outsie the pan, this would work wouldn't it? The electricity will travel through my fingers! I know this as a fact, but there is some electrical resistance.
