I know I’m on vacation, but this seems important: for the first time, the Department of Homeland Security has deemed an entire state of matter to be a national security risk.
Cosmic Variance is a group blog by people who, coincidentally or not, all happen to be physicists and astrophysicists:
Our day (and night) jobs notwithstanding, the blog is about whatever we find interesting — science, to be sure, but also arts, politics, culture, technology, academia, and miscellaneous trivia. We have similar outlooks on many things, widely disparate opinions about others, and will do our best to keep the discourse reasonably elevated.

Please tell me I can get this on a T-shirt! (It would totally solve the problem of which smart-alecky T-shirt to wear on international flights.)

You’d imagine the right time to do this would have been after the 2004 tsunami. Water is vicious. As an extra bonus we all consist of some 70% water so finally Bush has an argument to treat everyone as a terrorist.

I am getting awfully tired of the bad rep that unenlightened non-scientists have been giving to “dihydrogen monoxide” (DHMO). They tell you that inhaling it can be deadly, prolonged exposure to its solid form can cause tissue damage, whatever.
Dont fall for the hype.
In the first place, as soon as someone calls it “dihydrogen monoxide”, you know that you are dealing with a non-scientist with an agenda. The correct scientific nomenclature is “hydrogen hydroxide”. Why do the critics call it DHMO? Because it just sounds scarier and people are more likely to liken it to carbon monoxide in their minds.
In the second place, the dangers of hydrogen hydroxide have been greatly exagerated. Anyone who works with or deals with hydrogen hydroxide on a regular basis can eliminate most of the dangers of it with a few simple precautions. Simply by avoiding inhalation and wearing protective gear when dealing with it solid and gasseous states, you can deal with this relatively benign substance safely.
Secondly, studies have shown that there are several animals that require hydrogen hydroxide on a regular basis in order to survive. While it is true that hydrogen hydroxide has been found in the tumors of cancer patients, many people have been exposed to hydrogen hydroxide in laboratory conditions with no ill effects. Many of the health issues surrounding hydrogen hydroxide are not even about hydrogen hydroxide, but rather other contaminants. Pure hydrogen hydroxide can be perfectly safe.
So the next time someone starts telling you about the dangers of “dihydrogen monoxide” feel free to point out the error of their ways. And just because I know that people will be maiking the accusation, no, I have never recieved money, good, or services from the “dihydogen monoxide” lobby for presenting my opinion.

With Apologies to BunBun vonWhiskers:
Protection of Civilians from Terrorists
And the Dangers of Marijuana and Other Natural Chemicals
Unenlightened non-scientists have been giving a bad rap to “dihydrogen monoxide” (DHMO). They tell you that inhaling it can be deadly, prolonged exposure to its solid form can cause tissue damage, whatever. It sounds suspiciously like the unscientific campaign against common, roadside-grown marijuana, and probably comes from the same sources: Unelected high officials in federal government having their first taste of power, urged on by elected officials who profess to want to “protect” citizens…but, only if reelected.
Don’t fall for the hype.
In the first place, as soon as someone calls it “dihydrogen monoxide”, you know that you are dealing with a non-scientist with an agenda. The correct scientific nomenclature is “hydrogen hydroxide”.

Many of the health issues surrounding hydrogen hydroxide are not even about hydrogen hydroxide, but rather other contaminants. Pure hydrogen hydroxide can be perfectly safe.
And, remember, this is just more of the same unscientific thinking that has led to marijuana being claimed to have “high potential for abuse,” “no currently accepted medical use,” and lacking in “accepted safety for use.” There is ample evidence to the contrary, but those who would hold citizens in fear as a political means for getting reelected are not interested in reality…only control.
So the next time someone starts telling you about the dangers of “dihydrogen monoxide” (or marijuana) make it a point to show them the error of their ways. And just because I know that people will be making the accusation, no, I have never received money, good, or services from the “dihydogen monoxide” or “marijuana” lobbies for presenting my opinion.

And I would just like to see the reaction on the face of a suspected terrorist after they’d been required to take a swallow of either industrial grade Hydrogen Peroxide, Concentrated Sulferic Acid or Acetone. And our fine chemically illiterate TSA’s must be thinking that all the other fluids in that trash can will do an effective job of diluting out that stuff.

Critical point?
[...]Have we reached a critical point?
August 14th, 2006 at 4:35 pm
[...] So, after new terrorist attempts, we are now at a point where an entire state of matter poses an international security risk. We have become witness to the fact that security measurements are in fact degrading shadow plays to create the impression that something is done. This time so obvious that it becomes a giant laugh, and people are mostly concerned about what will follow the inevitable moment when people will have to fly naked chained to their seat…I propose hitting travellers over the head with a brick and piling them in the cargo bay (well I would prefer that way of flying anyway). So while all liquids have to be collected (by pouring them all into one container!), I have another question: What difference did it make that noone was hurt this time? Not much, did it? So I have a nice plot for a thriller in my head right now: Some terrorist boss plans attacks, and has some front men who believe they are supposed to execute them. But in fact they only have to plan and play out the preparations, because just then the boss uses his channels to inform the police. He never gets caught, only the front men. But the world panics and his goals are reached anyway…until one day some front men act autonomously and execute a plan… I can only say: As long as the authorities react as they did in the London case, almost all the goals of the terrorists have been reached. Go and read newspapers. Read serious blogs. Be informed, have an opinion, don’t panic and be angry when your rights are cut in the name of safety. [...]

The DHMO Song
Mark A. Mandel, © 1997_to the tune of “Battle Hymn of the Republic”
There’s a chemical that poses deadly danger to us all
If we don’t eliminate it, we are headed for a fall
But our governments refuse to see the writing on the wall
They’re going to let us die!
CHORUS (after every verse):
Ban dihydrogen monoxide!
Ban dihydrogen monoxide!
Ban dihydrogen monoxide
Before it kills us all!
Dihydrogen monoxide is a chemical to fear
Uncounted thousands die of inhalation every year
Yet the FDA allows it in our burgers, beans, and beer
And never questions why!
In gaseous form it’s subtle, without color, taste, or smell
But it’s part of acid rain, and it’s a greenhouse gas as well
It’s also found in car exhaust, which makes our cities Hell
And dirties up the sky!
It’s widely used by industry, and agriculture too
They dump it on the ground or in the river when they’re through
And from the ecosystem it gets into me and you
Which they dare not deny!
You’ll find dihydrogen monoxide everywhere you go
In rivers, oceans, lakes, and streams, in air and soil and snow
Its quantitative formula is simply H2O —
You’ll get it if you try!
This verse contributed by Gary McGath]
How far DHMO has spread no one can safely tell.
They’ve found it on Europa, and it’s on our Moon as well.
It may well turn our Solar System to a living hell!
It’s filling up the sky!
This verse contributed by Erik Von Halle
It kills the little children in the safety of their pools,
It make the politicians always sound like fools,
Linked to Hypothermia a death that kills and cools
It’s going to kill us all.

the reality of chemistry is that it’s trivial to find two relatively harmless compounds that can be mixed to form a high explosive.
at university I knew someone who was quite adept at making Lead Azide, a high explosive in power form made by mixing two solutions, sodium azide and lead nitrate. Although toxic, you could probably taste the ingredients without flinching or dying on the spot! Lead azide was abandoned in mining as it was so dangerous that nitroglycerine was much safer!
http://en.wikipedia.org/wiki/Lead_azide
these days, you’ll probably find that trying to buy any azide compound will get funny looks at any industrial supplier!
