While foil may work, its effectiveness should drop off quickly, also it may randomly distort signal patterns. See http://en.wikipedia.org/wiki/Foil_hat. -- For some reason, the United States is the only country on Earth where accidents don't happen it's always somebody's fault, and you can sue that somebody for neglect.
