RF-Blocking Wallpaper

spitefulcrow writes "Silicon.com is reporting on a new application for RF-absorbing materials: Wallpaper that blocks Wi-Fi. BAE, the British defense contractor, has announced that the same material used to foil radar by stealth bombers can be used to selectively block certain frequencies and prevent wireless networking signals from entering or exiting a building. Is this the next take on lining the walls with lead?"

Wallpaper hats!

Tinfoil is just so passee these days.

forget walls.

I want to put this stuff on my car.

No more radar speed traps!

Not nearly as effective or attractive as aluminum. ;-P

Aluminum is the perfect medium for constructing an AFDB

1. Get a five foot sheet of aluminum foil (standard one foot wide Reynolds Wrap brand will do nicely.)
2. Fold the sheet four times into five equal segments so that you end up with a 1x1 foot square, making sure that you fold over the dull side of the foil leaving the square shiny* on both sides.
3. Use scissors to cut from one corner of the square to the center, making a straight line.
4. Bend the foil from one side of the cut under the other, making a slight cone. Again, make sure that the outside of the cone has a shiny side of the foil; this is VERY important.
5. Place the cone on your head and squash the top and sides to make it fit snugly.
6. Apply Scotch tape liberally making sure to secure the cut in the foil and any form-fitting creases made in step 5.
7. Use more tape to secure AFDB to your cranium.

*A Note About The Shiny Side:
It can't be stressed enough how important it is to have the shiny side pointing out. This is needed because the shiny side is most reflective to psychotronic radiation, while the dull side can actually, in certain environmental conditions, absorb it. However, as is illustrated in the instructions above, it is also wise to complement this with a layer of foil pointing shiny side in. This will keep your brain waves, which are also reflected by the shiny side, from being picked up by mind-reading equipment. There is a small number of aluminum foil researchers who believe that this may cause an alpha-wave harmonic to build up in the skull resulting in memory loss or pseudo-religious visions, but their findings have never been replicated by the aluminum foil research community at large. Even if their findings are validated, the risk involved is small compared to the potential of mind-intrusion.

Sounds good, where can I download it?

I keep telling my mom that my room is classified and off-limits. Now with my Stealth-fighter wallpaper, I'll be able to call the Feds any time she breaches the perimeter.
