Tin Hats Useless!

At MIT recently, they tested the permeability and opacity of aluminum-foil hats to various emissions, to see how well they actually work to block any telekinetically-imposed outside behavioral patterns on an otherwise innocent population. They published their results!
They found that the hats do block some transmissions, but amplify some wavelengths of electromagnetic energy… including a band reserved by the government!

We can only hope that terrorists and ad agencies don't get their hands on this technology. . . Thanks to the Bad Astronomy Blog for this story.
