Building a Simple Faraday Cage, by OhioGalt? Why, when you might already have one?

Another SWL'ing rip. Good to know, but why build something that just about everyone already has? [survivalblog.com]

Just about everyone has a microwave oven, maybe even a couple of old, trashed, ones kickin' around. Cut off the power cord, take out the rotator and plate, (If any...), and clean out the food junk inside. Voila!!!! Faraday Cage, right there.
