Lower right: Original Finnish Molotov cocktail withstorm match attached in Finland
AMolotov cocktail (among several other names –see§ Etymology) is ahand-thrownincendiary weapon consisting of afrangiblecontainer filled withflammable substances and equipped with afuse (typically aglass bottle filled withflammable liquids sealed with aclothwick). In use, the fuse attached to the container is lit and the weapon is thrown, shattering on impact. This ignites the flammable substances contained in the bottle and spreads flames as the fuel burns.
The name's origin came from thepropaganda Molotov produced during the Winter War, mainly his declaration on Soviet state radio thatincendiary bombing missions over Finland were actually "airborne humanitarian food deliveries" for their "starving" neighbours.[14][11][better source needed] As a result, the Finns sarcastically dubbed the Sovietincendiarycluster bombs "Molotov bread baskets" (Finnish:Molotovin leipäkori) in reference to Molotov's propaganda broadcasts.[15][11] When the hand-held bottle firebomb was developed to attack and destroy Soviet tanks, the Finns called it the "Molotov cocktail", as "a drink to go with his food parcels".[16][17]
Despite the now infamous name, the formal Finnish military term for the weapon type was, and continues to be, "burn-bottle" (Finnish:polttopullo,[11][3]Fenno-Swedish:brännflaska).[2]
The weapon most often known as the Molotov cocktail goes under a great variety of other names around the globe. Some are more formal than others but the weapon is often given a descriptive name in the respective language.
Nazi Germany –German:Brandflasche ('fire bottle') –Brandhandgranate ('fire hand grenade')[22]
Soviet Union –Russian:зажига́тельная буты́лка,romanized: zazhigátelnaya butýlka,lit. 'incendiary bottle' –Russian:буты́лка с горю́чей жи́дкостью,romanized: butýlka s goryúchey zhídkostyu,lit. 'bottle with combustible liquid'[23]
Match-style fuses for a Swedish, military grade molotov cocktail (Brännflaska)
A Molotov cocktail is a glass bottle containing a flammable substance such aspetrol (gasoline),alcohol or anapalm-like mixture and a source of ignition, such as a burning clothwick, held in place by the bottle's stopper. The wick is usually soaked in alcohol orkerosene rather than petrol. Forwinter warfare, a method of ignition has been to attachstorm matches to the side of the bottle, as these are less likely to be put out by wind.[26][8][9] Some examples are fitted withballast for improved throwing accuracy (such as filling1⁄3 of the bottle with sand).[27]
In action, the wick/match is lit and the bottle hurled at a target such as a vehicle or fortification. When the bottle smashes on impact, the ensuing cloud of fuel droplets and vapour is ignited by the attached wick, causing an immediatefireball followed by spreading flames as the remainder of the fuel is consumed.
Monarchists during the Spanish Civil War with fire bottle
Improvised incendiary devices of this type were used in warfare for the first time in theSpanish Civil War between July 1936 and April 1939,[31] before they became known as "Molotov cocktails". In 1936, GeneralFrancisco Franco orderedSpanish Nationalist forces to use the weapon against SovietT-26 tanks supporting theSpanish Republicans in a failed assault on the Nationalist stronghold ofSeseña, nearToledo, 40 km (25 mi) south ofMadrid.[32] After that, both sides used simple petrol bombs set fire with toxic gas or petrol-soakedblankets with some success.Tom Wintringham, a veteran of theInternational Brigades, later publicised his recommended method of using them:
We made use of "petrol bombs" roughly as follows: take a 2lb glass jam jar. Fill with petrol. Take a heavy curtain, half a blanket, or some other heavy material. Wrap this over the mouth of the jar, tie it round the neck with string, leave the ends of the material hanging free. When you want to use it have somebody standing by with a light [i.e., a source of ignition]. Put a corner of the material down in front of you, turn the bottle over so that petrol soaks out round the mouth of the bottle and drips on to this corner of the material. Turn the bottle right way up again, hold it in your right hand, most of the blanket bunched beneath the bottle, with your left hand take the blanket near the corner that is wetted with petrol. Wait for your tank. When near enough, your pal [or comrade-in-arms] lights the petrol soaked corner of the blanket. Throw the bottle and blanket as soon as this corner is flaring. (You cannot throw it far.) See that it drops in front of the tank. The blanket should catch in the tracks or in a cog-wheel, or wind itself round an axle. The bottle will smash, but the petrol should soak the blanket well enough to make a really healthy fire which will burn the rubber wheels on which the tank track runs, set fire to the carburettor or frizzle the crew. Do not play with these things. They are highly dangerous.[33]
TheBattle of Khalkhin Gol, a border conflict of 1939 ostensibly betweenMongolia andManchukuo, saw heavy fighting betweenJapanese andSoviet forces. Short of anti-tank equipment, Japanese infantry attacked Soviet tanks with gasoline-filled bottles. Japanese infantrymen claimed that several hundred Soviet tanks had been destroyed this way, though Soviet loss records do not support this assessment.[34]
Finnish soldiers in theWinter War. Tanks were destroyed with satchel charges and Molotov cocktails. The bottle hasstorm matches instead of a rag for afuse.
On 30 November 1939, theSoviet Union attacked Finland, starting what came to be known as theWinter War. TheFinnish perfected the design and tactical use of the petrol bomb. The fuel for the Molotov cocktail was refined to a slightly sticky mixture of alcohol,kerosene,tar, andpotassium chlorate. Further refinements included the attachment of wind-proof matches or a phial of chemicals that would ignite on breakage, thereby removing the need to pre-ignite the bottle, and leaving the bottle about one-third empty was found to make breaking more likely.[26]
A BritishWar Office report dated June 1940 noted that:
The Finns' policy was to allow the Russian tanks to penetrate their defences, even inducing them to do so by 'canalising' them through gaps and concentrating their small arms fire on the infantry following them. The tanks that penetrated were taken on by gun fire in the open and by small parties of men armed with explosive charges and petrol bombs in the forests and villages... The essence of the policy was the separation of theAFVs from the infantry, as once on their own the tank has many blind spots and once brought to a stop can be disposed of at leisure.[35]
Molotov cocktails were eventually mass-produced by theAlko corporation at itsRajamäki distillery, bundled withmatches to light them.[5] A 500 ml (0.53 US qt) bottle was filled with a mixture of petrol and paraffin, plus a small amount of tar. The basic bottle had two longpyrotechnicstorm matches attached to either side. Before use, one or both of the matches were lit; when the bottle broke on impact, the mixture ignited. The storm matches were found to be safer to use than a burning rag on the mouth of the bottle. There was also an "A bottle". This replaced the matches with a small ampoule inside the bottle; it ignited when the bottle broke. By spring 1940 they had produced 542,104 bottles.[36]

Early in 1940, withthe prospect of immediate invasion, the possibilities of the petrol bomb gripped the imagination of the British public. For laypersons, the petrol bomb had the benefit of using entirely familiar and available materials,[37] and they were quickly improvised in large numbers, with the intention of using them against enemytanks.[38]
The Finns had found that they were effective when used in the right way and in sufficient numbers. Although the experience of the Spanish Civil War received more publicity, the more sophisticated petroleum warfare tactics of the Finns were not lost on British commanders. In his 5 June address toLDV leaders,General Ironside said:
I want to develop this thing they developed in Finland, called the "Molotov cocktail", a bottle filled with resin, petrol and tar which if thrown on top of a tank will ignite, and if you throw half a dozen or more on it you have them cooked. It is quite an effective thing. If you can use your ingenuity, I give you a picture of a [road] block with two houses close to the block, overlooking it. There are many villages like that. Out of the top windows is the place to drop these things on the tank as it passes the block. It may only stop it for two minutes there, but it will be quite effective.[39]
Wintringham advised that a tank that was isolated from supporting infantry was potentially vulnerable to men who had the required determination and cunning to get close. Rifles or even a shotgun would be sufficient to persuade the crew to close all the hatches, and then the view from the tank is very limited; a turret-mounted machine gun has a very slow traverse and cannot hope to fend off attackers coming from all directions. Once sufficiently close, it is possible to hide where the tank's gunner cannot see: "The most dangerous distance away from a tank is 200 yards; the safest distance is six inches."[40] Petrol bombs will soon produce a pall of blinding smoke, and a well-placed explosive package or even a stout iron bar in the tracks can immobilise the vehicle, leaving it at the mercy of further petrol bombs – which will suffocate the engine and possibly the crew – or an explosive charge or anti-tank mine.
By August 1940, theWar Office produced training instructions for the creation and use of Molotov cocktails. The instructions suggested scoring the bottles vertically with a diamond to ensure breakage and providing fuel-soaked rag, windproof matches or a length of cinema film (then composed of highly flammablenitrocellulose) as a source of ignition.[41]
On 29 July 1940, manufacturers Albright & Wilson of Oldbury demonstrated to the RAF how their white phosphorus could be used to ignite incendiary bombs. The demonstration involved throwing glass bottles containing a mixture of petrol andphosphorus at pieces of wood and into a hut. On breaking, the phosphorus was exposed to the air and spontaneously ignited; the petrol also burned, resulting in a fierce fire. Because of safety concerns, the RAF was not interested inwhite phosphorus as a source of ignition, but the idea of a self-igniting petrol bomb took hold. Initially known as an A.W. bomb, it was officially named theNo. 76 Grenade, but more commonly known as the SIP (Self-Igniting Phosphorus) grenade. The perfected list of ingredients was white phosphorus,benzene, water and a two-inch strip of raw rubber; all in a half-pint bottle sealed with acrown stopper.[42] Over time, the rubber would slowly dissolve, making the contents slightly sticky, and the mixture would separate into two layers – this was intentional, and the grenade should not be shaken to mix the layers, as this would only delay ignition.[43] When thrown against a hard surface, the glass would shatter and the contents would instantly ignite, liberating choking fumes ofphosphorus pentoxide andsulfur dioxide as well as producing a great deal of heat.[42] Strict instructions were issued to store the grenades safely, preferably underwater and certainly never in a house.[42] Mainly issued to theHome Guard as an anti-tank weapon, it was produced in vast numbers; by August 1941 well over 6,000,000 had been manufactured.[44]
There were many who were sceptical about the efficacy of Molotov cocktails and SIP grenades against the more modern German tanks. Weapon designerStuart Macrae witnessed a trial of the SIP grenades atFarnborough: "There was some concern that, if the tank drivers could not pull up quickly enough and hop out, they were likely to be frizzled to death, but after looking at the bottles they said they would be happy to take a chance."[45] The drivers were proved right, trials on modern British tanks confirmed that Molotov and SIP grenades caused the occupants of the tanks "no inconvenience whatsoever."[46]
Wintringham, though enthusiastic about improvised weapons, cautioned against a reliance on petrol bombs and repeatedly emphasised the importance of using explosive charges.[47][48]
The U.S. army designated Molotov cocktails as frangible grenades. They presented a notable amount of variations, from those that used thin fuel with varied ignition systems, to those that used obscurants andchemical weapons. Various frangible grenade designs were developed, with those investiged by the NDRC showing the highest technological level. These incendiary devices employed the most technologically advanced fillers in the conflict.
TheM1 frangible grenade was the standard US device, but each division of the army could come up with its own. Two non-industrial models of these grenades were developed and manufactured in a certain quantity. In all, about five thousand were manufactured.[49] The frangible grenades featured standardized chemical igniters, some were specific to each flammable filler.
Most of the frangible devices were made in an improvised way, with no standardization regarding the bottle and filling.[50] The frangible grenades were eventually declared obsolete,[50] due to the very limited destructive effect.[51]
ThePolish Home Army developed a version[54] which ignited on impact without the need of a wick. Ignition was caused by a reaction between concentratedsulfuric acid mixed with the fuel and a mixture ofpotassium chlorate and sugar which wascrystallized from solution onto a rag attached to the bottle.
During theNorwegian campaign in 1940 the Norwegian Army lacking suitable anti-tank weaponry had to rely on petrol bombs and other improvised weapons to fight German armored vehicles. Instructions from Norwegian High Command sent to army units in April 1940 encouraged soldiers to start ad-hoc production of "Hitler cocktails" (a different take on the Finnish nickname for the weapon) to combat tanks and armored cars.[55] During the campaign there were instances of petrol bombs being relatively effective against the lighter tanks employed in Norway by Germany, such as thePanzer I andPanzer II.
During before National resistance, the Vietminh made molotov cocktail[56] for fight against the French tank and an armored vehicle. And in the Vietnam War, during the struggle movement of Saigon students during the resistance war against America to save the country, a prominent event was the students occupying the Cambodian Embassy to protest against the Lon Nol government's murder of overseas Vietnamese.The defense was well-arranged with all the weapons available and those taken from the field police. They also made hundreds of petrol bombs from easily available materials such as foam and rubber crepe stuffed into coke bottles, sardine bottles filled with petrol..., a terrifying weapon for the field police.[57]
Duringthe Troubles, both theProvisional Irish Republican Army (PIRA) and civilians used petrol bombs, although with different uses. Civilians tended to use petrol bombs and rocks againstpolice officers in riots;[58] however, the PIRA tended to use them in attacks rather than in self-defence. Over time, as the PIRA became more co-ordinated, it shifted to usingIEDs rather than petrol bombs.[59]
During theSecond Battle of Fallujah in 2004,U.S. Marines employed Molotov cocktails made with "one part liquid laundry detergent, two parts gas [gasoline]" while clearing houses "when contact is made in a house and the enemy must be burned out". The tactic "was developed in response to the enemy's tactics" ofguerrilla warfare and particularlymartyrdom tactics which often resulted in U.S. Marine casualties. The cocktail was a less expedient alternative towhite phosphorus mortar rounds or propane tanks detonated withC4 (nicknamed the "House Guest"), all of which proved effective at burning out engaged enemy combatants.[60]
During theUkrainian Defense Ministry told civilians to make Molotov cocktails, locally called "Bandera smoothies",[61] to fight Russian troops.[62] The defense ministry distributed a recipe for producing Molotov cocktails to civilians through Ukrainian television, which included the use of styrofoam as a thickening agent to aid in helping the burning liquid stick to vehicles or other targets.[63] The Pravda Brewery ofLviv, which converted from making beer to Molotov cocktails, said that its recipe was "3 cups polystyrene, 2 cups grated soap, 500 millilitres gasoline, 100 millilitres oil, 1 jumbotampon fuse."[64] The Russian media control organisationRoskomnadzor suedTwitter for not removing instructions for how to prepare and use molotov cocktails, so that Twitter had to pay a fine of 3 million roubles (US$41,000).[65]
InBangladesh, during anti-government protests in 2013 and 2014, many buses and cars were targeted with petrol bombs. A number of people burned to death and many more were injured due to these attacks.[68][69]
During the2019–20 Hong Kong protests,riots broke out and Molotov cocktails were used to attack the police and create roadblocks. They were also used to attack anMTR station, causing severe damage.[70] A journalist was also struck by a Molotov cocktail during the protests.[71]
Molotov cocktails were used by some during the riots following the 2020George Floyd protests in the United States.[72]
In 2025, a man in Boulder, Colorado, United States used a Molotov cocktail and an improvised flamethrower toattack a group of peaceful demonstrators calling for the release of Israeli hostages.[73]
During the2014–17 Venezuelan protests, protesters used Molotov cocktails similar to those used by demonstrators in other countries.[74] As the2017 Venezuelan protests intensified, demonstrators began using "Puputovs" (a portmanteau of the words "poo-poo" and "Molotov"), with glass containers filled with excrement being thrown at authorities after thePSUV ruling-party official,Jacqueline Faría, mocked protesters who had to crawl through sewage inCaracas'Guaire River to avoid tear gas.[75][76]
On 8 May, the hashtag #puputov became the top trending hashtag on Twitter in Venezuela, as reports of authorities vomiting after being drenched in excrement began to circulate.[76][77] A month later, on 4 June 2017, duringprotests against Donald Trump inPortland, Oregon, police claimed protesters began throwing balloons filled with "unknown, foul-smelling liquid" at officers.[78]
In Canada, Molotov cocktails are considered an "explosive substance" under theCriminal Code (Canada) and possession is illegal. Under section 82:"Possession of explosive (1) Every person who, without lawful excuse, makes or has in their possession or under their care or control any explosive substance is guilty of (a) an indictable offence and liable to imprisonment for a term of not more than five years; or (b) an offence punishable on summary conviction."[79]
In the United States, Molotov cocktails are considered "destructive devices" under theNational Firearms Act and are regulated by theATF.[80] Wil Casey Floyd, fromElkhart Lake, Wisconsin, was arrested after throwing Molotov cocktails at Seattle police officers during a protest in May 2016; he pleaded guilty for using the incendiary devices in February 2018.[81]
InSimpson County, Kentucky, 20-year-old Trey Alexander Gwathney-Law attempted to burn Franklin-Simpson County Middle School with five Molotov cocktails; he was found guilty of making and possessing illegal firearms and was sentenced to 20 years in prison in 2018.[82]
Due to the Molotov's ease of production and use by civilian forces, the Molotov cocktail has become a symbol of civil uprising andrevolution. The Molotov's extensive use by civilian, andpartisan forces has also thereby led to the Molotov becoming a symbol representing civil unrest.[83][84][85][86][87] The contrast of a Molotov cocktail and an organized force has become a popular symbol inpopular culture,[88] and is often utilized as a weapon in variousvideo games.
