When I was 12 my friend and I made a "TV" Jammer that ran off a 9V battery. We drove the old man downstairs crazy when he tried to watch ABC News. I don't remember fearing for a second that the FCC would drive up in a white van.
However, I don't think I'd recommend open door microwave ovens in a classroom. That might be borderline stupid. Eighteen year old soldiers in Alaska used to stand in front of the military radar dish to warm up... they didn't quite understand why. > And of course, the "jammer" you are trying to make, > will be highly illegal, and the FCC can drive up in > their white van and haul all your electronics away.
