CHEAP FARADAY CAGE ?

[Highlander]

Its whats on the outside that matters, and the outside is aluminum,.. that's the conductive stuff that will send any electrical current around the cage and hopefully to earth, the more tape or thicker the protecting metal the better... any chink in the amour, or if the item inside is touching the outside,.. then it will not protect anything

No question is stupid if you dont know the answer
