Tinfoil Hats *Magnify* Radiation  |  (2006/12/04 12:00)

Just linking this piece of silliness because I read it over the summer and then lost it and needed it in a conversation recently.

MIT grad students investigate the effectiveness of tin foil hats "Overall, the foil effectively weakened radio waves by up to 10 decibels over most of the frequency spectrum (there were no significant differences among helmet shapes). But at 1.2 and 2.6 GHz which fall within the band reserved for government satellites, GPS systems and mobile phone corporations passage through the foil amplified these waves by 20 to 30 decibels"
