And for it to be effective it needs a copper foil lining.
“And for it to be effective it needs a copper foil lining.”
You sure about that? Copper is pretty darn conductive . . .
We were on a job and there was a gal near the lunch place with a tin-foil hat on. I told her that it would work a lot better if it was grounded to the earth. If she could wait until the end of the day I’d bring some wire back for her. She said she hung around there all day.
The following day she was still wearing her hat - but now with the thin strand of copper wire dragging behind her. I was much younger back then. Not really cruel I guess, but still.
