I have a cable here that is interesting. When I first saw it I thought how strange, a cable that is multi-stranded bare wire for this application (connecting a camera). Then I looked at it under a microscope and realized not only is it insulated wire, it is shielded wire. Mindblowing. I pity the people that have to handle that stuff.
