There is a small amount of truth or reason to be found in the tin-foil hat story. A well constructed tin-foil enclosure would approximate a Faraday cage, reducing the amount of (notionally harmless) radiofrequency electromagnetic radiation inside. A common high school physics demonstration involves placing an AM radio on tinfoil, and then covering the radio with a metal bucket. This leads to a noticeable reduction in signal strength. The efficiency of such an enclosure in blocking such radiation depends on the thickness of the tin-foil, as dictated by the skin depth, the distance the radiation can propagate in a particular non-ideal conductor. For half-millimeter-thick tin-foil, radiation above about 20 kHz (i.e., including both AM and FM bands) would be partially blocked. The effectiveness of the tin-foil hat in stopping radio waves is greatly reduced by the fact that it is not a complete enclosure. Placing an AM radio under a metal bucket without a conductive layer underneath demonstrates the relative ineffectiveness of such a setup. Indeed, because the effect of an ungrounded Faraday cage is to partially reflect the incident radiation, a radio wave that is incident on the inner surface of the hat (i.e., coming from underneath the hat-wearer) would be reflected and partially 'focused' towards the user's brain. While tin-foil hats may have originated in some understanding of the Faraday cage effect, the use of such a hat to attenuate radio waves belong properly to the realm of pseudoscience.

Kinda stylish, though.

I'll bet that thing gets real hot in the sun cook the gray matter. razz

Did you use Frisco's head for the model or just make it from memory? .

Sorry Tom, that was just to good to pass up .

I won't even bother with the obvious phallic references in relation to the cranium.

Larry, if thats you, bring it with you next April....Between Hals
armor suit and that tin foil condom. You'll be the coolest one there.

I've probably been called a "dickhead" from time to time, but I don't think I've ever been called a "pinhead."
One of the most prominant buildings on the San Francisco skyline is the Trans America building,..........called "Zippy The Pinhead Building" by the locals. Reminds me of it.

Larry, I dare you to wear that out on the golf course during a thunder storm .

Tom that just reminded me, way back when I was on my first tour in Europe I was envolved with a large releife effort mounted by the UN for South Africa. I was stationed in France,(very early 60's), with 37 Trans. Gp. I large number convoy was organized to haul food and medical supplys to area's in South Africa during the trible riots.

On the trip down the we went through a small town named "Ras Chamboni", it was on the East coast of Kenya were Somali and Kenya meet. I was a Pvt. at the time so don't ask me why they didn't air drop the stuff, I can only think they were afraid it would not get to the people.

Any way I learned that this towns name translates to "Dicks Head", so how many folks do you know that might be from "Ras Chamboni"? :cd: .

(sounds funny, but look it up).

You are a RIOT my friend!

Did you get the 'approval' of the Great Northwest & Lower Texas Cowboy Crew to have this picture posted? :cd:
