I did a search for “how to make a tin foil hat” and Google hath responded over one million times. Yea verily. Here are my reviews of Select Websites listed on the first couple of pages:
The Aluminum Foil Deflector Beanie: excellent site for the most recent research in the SCIENCE behind hats of all sorts of foil-age. Includes the alarming report On the Effectiveness of Aluminium Foil Helmets: An Empirical Study*, and very nice set of instructions
*Rebuttal to the study, On the Effectiveness of Aluminium Foil Helmets: An Empirical Study here.
tinWiki.org – not exclusively devoted to tin foil hat making, they also research these things called conspiracies
This site has a much less informative set of instructions, not geared specifically towards deflecting mental rays…although a tin foil Pillbox hat could be stylish…
Fancy-schmancy “thought screen helmets” on this site. Also includes a photo of an alien, case histories and testimonials! They are anti-alien abductions, fyi.
Foil-hat.com has a blinky star background, and their slogan is: Because you totally know someone who needs one. They have testimonials, and a fairly nice gallery of hats, as well as custom Specialty Foil Hats starting at $4.95 which they will send you in the mail.
Those who are less visually oriented may want to check out tin foil hat making for Dummies on YouTube.
RATING: 7 It had a good beat, and I could dance to it.
…and finally, The Straight Dope tells us how it really is…
