Are Tinfoil Hats Less Ridiculous Than We Thought?

Tinfoil Hat Experiment
Tinfoil hats are our go-to mocking tool when it comes paranoid conspiracy theorists. But if this little YouTube experiment from MrfixitRick (a.k.a., Rick Crammond) is to be believed, we're wrong to laugh. (At the hat, at least. We're still laughing at the person.)

Sci-Art weirdo Rick demonstrates, by way of a cap covered in tinfoil, that the kitchen staple can actually block electromagnetic pulses. With a device called a beta-blocker radio, the Tesla-obsessed Canadian shows how a wireless modem pumps out electromagnetic pulses when turned on. Those pulses are clearly audible as an almost woodpecker-like thumping when the radio is placed close to the modem. But, when Rick puts his radio-cum-detector in the foil hat, the pulses practically disappear. It seems that the sheet of tinfoil acts as a sort of Faraday Cage, a barrier (usually a fine mesh of conductive metal) that blocks external sources of electromagnetic radiation.

Of course, this shouldn't come as a complete surprise. So called "booster bags," essentially shopping bags lined with aluminum foil, have been used for years to help shoplifters sneak items past security detectors in stores. But, just because the whole tinfoil hat thing seems to have some basis in sound scientific theory, don't expect us to stop mocking it anytime soon. [From: YouTube, via: Make]
