An interesting article on Israeli's new "completely organic" weapon.

It's called Skunk. http://news.bbc.co.uk/2/hi/middle_east/7646894.stm

:)

Time for us to start breaking out the yeast, baking soda and trying to find those "secret" ingredients....

Looks to me like good old media hoax.

Fecal matter, urine, and eggs baked by the sun a few days in a jam jar always worked wonders for us deviant children back in the day. One jar splatted against the side of someone's house was enough for them not to mow that side of the lawn for about a week.

I would imagine that a skatole (3-methylindole) in DMSO aerosol would be a pretty effective less-than-lethal weapon. Perhaps it could be spiced up with a splash of hydrogen sulfide, but one would have to be careful not to hit the lethal dose.

I find the duration that the smell sticks with you to be the most interesting part. Making people vomit and cry from a smell isn't too hard, but making that smell stick for 3 days seems like it would be pretty difficult.

Skatole has been shown to cause pulmonary edema in goats, sheep, rats, and some strains of mice.

Probably not the best option unless you don't mind that harm it may cause.

Finding something which is know for it's stink, extracting the fragrance and dispersing it in a solution may be an option. Cat urine/mould/rotten eggs/rotting flesh/rotting anything.

I remember hearing about a fragrance which is used to attract dingos. Maybe it's used universally for wild predators.

It had a foul smell and caused gagging etc. Was very hard to get rid of (could smell it on your hands up to 3 days after handling)

Has anyone heard of this substance?

So if the Chinese (the real power in this world now) get pissed off with the Israelis and Arabs bickering, they can just airspray the place with it, and then whoever still wants it can have it - as long as they stay there!

Chinese have enough problems with their billion people population, they don't have to act like some imperial power, and probably won't.

I don’t remember if it was posted here a few years ago, or I just read it somewhere, but the US military started a project to develop the smelliest stench for a less-than-lethal weapon and crowd control. I can’t seem to find the website and articles anymore.

The smell they are going after is a cross between vomit, rot, and feces, the three most offensive odors to people (putrecene, cadavarene, skatole). I remeber reading the university lab spilled one drop in a fume hood and the stench filled up the entire building for a few days afterwards.

I have been sitting back and waiting for the synthesis to be published in a journal or patent. The US military is going for the psychological angle developing the smelliest possible substance completely unbearable by every human being alive. Read that as trained soldiers, terrorists, and the biggest, meanest badasses on the block.

We already have the smelliest substance possible, they just needs to swab the crevices of dirty hippies.

Thioacetone is first that comes to my mind... but there is so many thiols and amines eager to show their might :-).

I remember reading about something similar that they called 'Vile-X' IIRC. They placed a couple of drops on the roots of a fruit tree and all of the fruit borne by that tree was inedible due to the vile smell and taste produced by the chemical. Supposedly it was detectable to the human nose at the PPT level. :eek:

Or do like Green Peace and toss gallon jugs of Methyl Mercaptan.

Mega - I had a bit of a look around. Seems that it is still under wraps, but the things touted to be absolutely vile (hence useful to us) are "Who Me?" developed in WWII, "Bathroom Malodor" (developed by the US Government for "testing cleaning products") and something called "Stench Soup".

Here (http://www.pubmedcentral.nih.gov/picrender.fcgi?artid=1259269&blobtype=pdf) is a link to a synthesis of Putrescine.

I cannot seem to find a synth for the "Bathroom Malodor" or for the "Stench Soup" but I have found this patent (http://www.freepatentsonline.com/4009253.html) about defeating malodorants, in which they make up "Bathroom Malodor" but I don't know if it is the same one.

Various Malodor syntheses can be found here (http://www.patentstorm.us/patents/7157411/description.html)

This pdf (http://www.dtic.mil/ndia/nld4/bickford.pdf) contains some tests regarding Malodors and their effects/ranking among various cultures.
