It looks like the copper wire has 2 wires in it. This means that dirty electricity can travel in a loop. One wire cannot.

I sleep cocooned in a silver sheet. It's the best sleep of my life. I am EMF sensitive because I still have so much metal garbage in me. When I get a headache from being around cellphones, it only takes 20mins wrapped in my cocoon for me to feel great again.
