MIT's Study: Effectiveness of Aluminium Foil Helmets

Background
Tinfoil hat is a general term for headgear made from one or more sheets of tin foil, aluminium foil, or similar metallic material. Some people wear the helmets in the belief that it shields their brains from the undesirable influence of harmful electromagnetic fields, as well as governmental mind control or mind reading. Other people believe in the efficacy of tin-foil hats to prevent abduction by space aliens, or to block unpleasant experiences such as strange voices in their heads. Such highly strange phenomena probably depend in some fashion upon microwave radiation (see illustrative, high-tech photo).

The Study
In February last year, four of MIT's brightest from the Electrical Engineering and Computer Science department reported the results of their carefully recorded empirical study. Ample photographic and video documentation (courtesy of Discover Channel's Daily Planet) are provided. Some may find the conclusion rather alarming. Folks who once used alumunum foil on their TV's rabbit ears to improve reception will likely not be surprised by the scientific results, however. Go here for the report. They will not let you down.
