[quote=@Forsythe] You don't need ruber for that, in fact it wouldn't help at all, the lead rather would. All you need is a faraday cage, which needs to be conductive material, to block E1, and E3 shouldn't be a problem as long as they are not plugged into a charger or a phone line :D [/quote] I luff you. Bahah. I usually throw rubber in there cause it "helps" convince people of the EMP blockage.
