Reference excerpt

Skunk is a malodorant, non-lethal weapon used for crowd control by the Israel Defense Forces (IDF) and marketed to militaries and law enforcement around the world. It was developed and is manufactured by Odortec, with two supporting companies, Man and Beit-Alfa Technologies. The liquid's strong odor is marketed as an improvement over other crowd control weapons (CCWs) such as rubber bullets and tear gas used by the IDF against Palestinian protestors. The IDF has been criticized for its tactics during deployment, including common use against people, businesses, and neighborhoods not involved in protests as a form of collective punishment.

Product

The material used is said to be an organic and non-toxic blend of baking powder, yeast, and other ingredients. Deriving its name from the animal of the same name which is known for its ability to spray a foul-smelling fluid, "Skunk" is dispersed as a form of yellow mist, fired from a water cannon, which leaves a powerful odor similar to rot or sewage on whatever it touches. Skunk is also sold in handheld canisters and in grenades which can be thrown or fired as projectiles (see riot gun). The company later marketed Skunk to law enforcement agencies worldwide, specifically American local police departments. Several US police departments, including the St. Louis Metropolitan Police Department, purchased it. A BBC reporter describes its effects as follows:

Imagine the worst, most foul thing you have ever smelled. An overpowering mix of rotting meat, old socks that haven’t been washed for weeks – topped off with the pungent waft of an open sewer. . .Imagine being covered in the stuff as it is liberally sprayed from a water cannon. Then imagine not being able to get rid of the stench for at least three days, no matter how often you try to scrub yourself clean. A reporter for Reuters described its effect in the following words:

Imagine taking a chunk of rotting corpse from a stagnant sewer, placing it in a blender and spraying the filthy liquid in your face. Your gag reflex goes off the charts and you can't escape, because the nauseating stench persists for days. However, when tested in India, the product failed miserably:

We used it on a captive crowd consisting of CRPF personnel and general public. But they managed to tolerate the smell without much difficulty. [...] Those who can ignore [the] smell can drink the liquid also. In December 2017, Haaretz reported:

Skunk is liable to cause physical harm, such as intense nausea, vomiting and skin rashes, in addition to any injury resulting from the powerful force of the spray. Examinations by police and army medical teams in the past also indicated that the excessive coughing caused by exposure can result in suffocation. Some report that the smell is so potent it can linger on clothes for months, if not years.

Removal The company sells a special soap – available to authorities but not the general public – that neutralises the smell of skunk water if officers are accidentally sprayed. It has been suggested that rubbing a surface contaminated with skunk with ketchup, similar to treating a real skunk spray with tomato juice, and then washing it off, may diminish perception of the odor (due to the effects of olfactory fatigue). In 1993, American chemist Paul Krebaum developed a compound that chemically neutralizes natural skunk spray by changing the odor-causing thiols into odorless acids. This compound can be prepared as a mixture of: 1 quart of 3% hydrogen peroxide, ¼ cup of baking soda, and 1-2 teaspoons of liquid dish soap.

History

The first attempts at developing an odor-based form of crowd control began in Israel in 2004 by Rafael. The IDF reconsidered at the time a change in its open fire procedures, and adopting other crowd dispersal methods after an Israeli demonstrator, Gil Na'amati (21), was shot during a protest over the separation barrier, near the West Bank village of Mas-ha in late 2003. It reportedly does not wash off easily and may linger on clothes for up to five years. The development of Skunk followed numerous accusations against Israeli forces that they often employ disproportionate force in clashes with Palestinian protesters (e.g. using rubber bullets or tear gas), which has led them to seek new, non-lethal but effective methods of crowd control. Skunk was first reported to be used for crowd control in August 2008 in the Palestinian village of Ni'lin where daily protests had been taking place in response to the construction of a security barrier. Spraying the liquid has developed into one of the preferred measures adopted by the IDF to meet the challenge of civil disobedience and demonstrations by Palestinians. The tactic was devised to tamp down organized civilian protests in the West Bank. It has been used regularly against the villagers of Bil'in, Ni'lin, Kafr Qaddum, and Nabi Salih, where weekly protests against the occupation are practiced. In Hebron it was used on the 26 February 2012 to disperse a crowd of an estimated 1,000 people which clashed with Israeli soldiers during a protest described as commemorating the anniversary of the Cave of the Patriarchs Massacre or as pressing for the reopening of the zone of Shuhada Street. A funeral procession waiting for the riots to be dispersed were also doused with the liquid. It has been used during clashes with "Palestinian protesters calling for the release of Palestinian hunger striker Mohammad Allan near Barzilai Medical Center" in the Israeli city of Ashkelon. In 2017, Israeli forces began using Skunk against ultra-Orthodox Jewish protesters. In January 2024, students at a pro-Palestine demonstration at Columbia University were allegedly attacked with Skunk by individuals disguised as fellow protesters. One victim, who claimed that Palestinian friends recognized the odor as Skunk, described it as having the smell of "poop mixed with decaying animal." Victims of the attack reported difficulty removing the odor from their clothes and other possessions, and that the effects of the spray including its odor, skin irritation, nausea, and dizziness continue days after the attack despite efforts to remove it. The incident is currently being investigated by the New York City Police Department as a potential hate crime.

Worked examples

Example 1 — a first encounter with Skunk (weapon)

Start with the simplest possible case. Write down what Skunk (weapon) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Skunk (weapon) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Skunk (weapon) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Skunk (weapon)

In research
Skunk (weapon) appears in chemistry research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Skunk (weapon) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Skunk (weapon) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Chemical weapons, Foul-smelling chemicals, Incapacitating agents, so understanding it makes those chapters shorter.
In everyday life
Look for Skunk (weapon) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
