On Clandestine Surveillance Cameras in your Microwave Ovens.
These insidious gadgets can be distracted in much the same manner as a stealth fighter distracts incoming ordinance by firing off a chaff canister that works as an aluminum foil radar reflector. All you have to do is fabricate yourself some headgear with Reynold's Wrap aluminum foil (generic brands are much less effective) and a couple of steel coat hangers. It is necessary for this headgear to descend at minimum to the mid eyebrow level on the surveillance subject's face and to completely cover the surveillance subject's ears. This headgear must also be outfitted with two steel coat hanger disruptor antennas, oriented at 90 degree angles to each other in order to cover all 380 degrees around the surveillance subject.
