a fiendish plot to conserve jet fuel

Americans Shrug at Phony Binary Explosives Threat Ted Rall
Industry analysts say travelers aren't afraid of being blown up by terrorists. They're right. Hundreds of millions of people fly each year; very few end up shredded among the wreckage of an office tower. But passengers are afraid. They fear that the government's draconian security measures will make them miss their flights. That real and wholly justifiable fear has already cut ticket sales by as much as 20 percent.

According to the respected and irreverent British technology publication The Register, the plot--if it existed--was a joke (...) "First," wrote The Register, "you've got to get adequately concentrated hydrogen peroxide. This is hard to come by, so a large quantity of the three per cent solution sold in pharmacies might have to be concentrated by boiling off the water...Take your hydrogen peroxide, acetone, and sulfuric acid, measure them very carefully, and put them into drink bottles for convenient smuggling onto a plane. It's all right to mix the peroxide and acetone in one container, so long as it remains cool. Don't forget to bring several frozen gel-packs (preferably in a Styrofoam chiller deceptively marked "perishable foods"), a thermometer, a large beaker, a stirring rod, and a medicine dropper. You're going to need them.
"It's best to fly first class and order champagne. The bucket full of ice water, which the airline ought to supply, might possibly be adequate...Once the plane is over the ocean, very discreetly bring all of your gear into the toilet. You might need to make several trips to avoid drawing attention. Once your kit is in place, put a beaker containing the peroxide/acetone mixture into the ice water bath (champagne bucket), and start adding the acid, drop by drop, while stirring constantly. Watch the reaction temperature carefully. The mixture will heat, and if it gets too hot, you'll end up with a weak explosive. In fact, if it gets really hot, you'll get a premature explosion possibly sufficient to kill you, but probably no one else.

Helpful, that this latest terror plot will help to conserve massive amounts of jet fuel in an era of extremely tight supply...

Another trend to keep an eye on. Terror in the skies! Take the horse.
