Delicate Chemestry at 10k M in a 1M x 1M space

A dose of reality from the Redg:

Exerpts from a great article:

<snip>

The funny thing about these movies is, we never learn just which two chemicals can be handled safely when separate, yet instantly blow us all to kingdom come when combined. Nevertheless, we maintain a great eagerness to believe in these substances, chiefly because action movies wouldn't be as much fun if we didn't.

Now we have news of the recent, supposedly real-world, terrorist plot to destroy commercial airplanes by smuggling onboard the benign precursors to a deadly explosive, and mixing up a batch of liquid death in the lavatories. So, The Register has got to ask, were these guys for real, or have they, and the counterterrorist officials supposedly protecting us, been watching too many action movies?

We're told that the suspects were planning to use TATP, or triacetone triperoxide, a high explosive that supposedly can be made from common household chemicals unlikely to be caught by airport screeners. A little hair dye, drain cleaner, and paint thinner - all easily concealed in drinks bottles - and the forces of evil have effectively smuggled a deadly bomb onboard your plane.

Or at least that's what we're hearing, and loudly, through the mainstream media and its legions of so-called "terrorism experts." But what do these experts know about chemistry? Less than they know about lobbying for Homeland Security pork, which is what most of them do for a living. But they've seen the same movies that you and I have seen, and so the myth of binary liquid explosives dies hard.

Better killing through chemistry

Making a quantity of TATP sufficient to bring down an airplane is not quite as simple as ducking into the toilet and mixing two harmless liquids together.

First, 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. Only this is risky, and can lead to mission failure by means of burning down your makeshift lab before a single infidel has been harmed.

But let's assume that you can obtain it in the required concentration, or cook it from a dilute solution without ruining your operation. Fine. The remaining ingredients, acetone and sulfuric acid, are far easier to obtain, and we can assume that you've got them on hand.

Now for the fun part. Take your hydrogen peroxide, acetone, and sulfuric acid, measure them very carefully, and put them into drinks 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 - especially if you have those cold gel-packs handy to supplement the ice, and the Styrofoam chiller handy for insulation - to get you through the cookery without starting a fire in the lavvie.

Action heroes

The al-Qaeda franchise will pour forth its bowl of pestilence and death. We know this because we've watched it countless times on TV and in the movies, just as our officials have done. Based on their behavior, it's reasonable to suspect that everything John Reid and Michael Chertoff know about counterterrorism, they learned watching the likes of Bruce Willis, Jean-Claude Van Damme, Vin Diesel, and The Rock (whose palpable homoerotic appeal it would be discourteous to emphasize).

It's a pity that our security rests in the hands of government officials who understand as little about terrorism as the Florida clowns who needed their informant to suggest attack scenarios, as the 21/7 London bombers who injured no one, as lunatic "shoe bomber" Richard Reid, as the Forest Gate nerve gas attackers who had no nerve gas, as the British nitwits who tried to acquire "red mercury," and as the recent binary liquid bomb attackers who had no binary liquid bombs.

For some real terror, picture twenty guys who understand op-sec, who are patient, realistic, clever, and willing to die, and who know what can be accomplished with a modest stash of dimethylmercury.

If you're curious about dimethylmercury(CH3)2Hg)'s effects:
Karen Wetterhahn (1949 - June 8, 1997) was a well-known professor of chemistry at Dartmouth College specializing in toxic metal exposure. On August 14, 1996 while working with an organic mercury compound called dimethylmercury, she spilled a drop or two on her latex glove. Several months later, she noticed some neurologic symptoms such as loss of balance and slurred speech. She was admitted to the hospital, where it was discovered that the single exposure to dimethylmercury had raised her blood mercury level to 4,000 micrograms per liter, or 80 times the toxic threshold. Despite aggressive chelation therapy, she fell into a coma and died a few months later, less than a year after her initial exposure.

Her death, despite use of gloves, a fume hood, and standard safety procedures, shocked her chemistry department. They tested various safety gloves against dimethylmercury, apparently for the first time ever, and found that most of them were penetrated in seconds. Dimethylmercury was in fairly wide use as a standard for calibrating diagnostic instruments. The discovery of its extreme toxicity and danger is directly due to Karen Wetterhahn's unfortunate accident. OSHA recommendations and MSD Sheets were changed in consequence and use of dimethylmercury has been highly discouraged.

Dartmouth has established an award in her name to encourage other women in science.

Nobody likes explosives?

I guess I miss judged this board. :wink:
