I do a lot of unrelated research into other topics of interest, BUT along the way I copy all the insulator related stories, cartoons, and advertisements that I find.

I have come across some wired insulator related cartoons, but this zinc one had me scratching my head.

I did not receive any response from this posting, so I guess nobody else understands this cartoon
