Explain it to me. I know that a faraday cage will protect your electronic items, but what items like ammo cans? Do they need to be grounded with some type of foam or padding inside them? Are there certain watches and compases that are resistant? Will security systems on prisons just open up and convicts escape? Will freezers just shut down or will they be safe since they are metal? How about homes that are built out of metal containers, or will it come through windows? I'm soooooo confused!
