Here's a story originally published back in the Seventies and carefully passed from hand to hand to newsgroup to newsgroup and now from blog to blog: <a href="http://www.illtel.denver.co.us/texts/make.an.Hbomb" source="" author="">How to Build an H-Bomb</a>. There's a lot of pseudo-realistic--sounding scientific babble about various chemical compounds and elements, but the home-liquefaction process guide takes the cake: <bq>First transform the gas into a liquid by subjecting it to pressure. You can use a bicycle pump for this. Then make a simple home centrifuge. Fill a standard-size bucket one-quarter full of liquid uranium hexafluoride. Attach a six-foot rope to the bucket handle. Now swing the rope (and attached bucket) around your head as fast as possible. Keep this up for about 45 minutes. Slow down gradually, and very gently put the bucket on the floor. The U-235, which is lighter, will have risen to the top, where it can be skimmed off like cream. Repeat this step until you have the required 10 pounds of uranium. (Safety note: Don't put all your enriched uranium hexafluoride in one bucket. Use at least two or three buckets and keep them in separate corners of the room. This will prevent the premature build-up of a critical mass.)</bq> Poor Binyam Mohamed, recently released from Guantànamo after seven years in captivity, admitted under torture that he had once read the article, but that it was a joke.<fn> Predictably, the part about researching an H-Bomb was passed on; the part about it being a rather transparent joke was not. <hr> <ft>See <a href="http://www.guardian.co.uk/commentisfree/libertycentral/2009/feb/21/barbara-ehrenreich-guantanamo" source="Guardian" author="Barbara Ehrenreich" title="My unwitting role in acts of torture: Our 1979 satire was not subtle.
