A Molotov cocktail is a hand-thrown incendiary weapon designed to start fires.

It typically consists of a frangible container, which is a container designed to break easily, filled with flammable liquids. The device is equipped with a fuse to ignite the contents upon impact. Because they are made from common household items, they are often categorized as improvised weapons. However, they have also been mass-produced by organized militaries during times of conflict. This versatility allows them to be used by various groups, including irregular soldiers, protesters, and even regular military units facing equipment shortages.

The mechanism of a Molotov cocktail relies on a specific sequence of physical actions. First, a source of ignition is attached to the container. This is often a cloth wick soaked in alcohol or kerosene, or sometimes specialized storm matches. The user lights this fuse and throws the bottle at a target, such as a vehicle or a fortification. Upon impact, the glass container shatters.

This breakage releases a cloud of fuel droplets and vapor. The flame from the active fuse immediately ignites this cloud, resulting in a sudden fireball. As the remaining fuel burns, the flames spread across the target.

Different versions of the device exist based on the desired effect. Some users add thickening agents to the fuel to change its properties. Substances like soap, tar, polystyrene foam, or rubber cement can be added to the mixture. These additives help the burning liquid adhere to surfaces rather than simply running off. Other variations focus on creating smoke rather than fire. "Smoke bottles" use a mixture of chemicals, such as sulfur trioxide dissolved in chlorosulfonic acid, to generate thick clouds. Unlike standard firebombs, these smoke bottles can react with the air and ignite automatically once the glass breaks.

The name "Molotov cocktail" has a unique and sarcastic origin. It was coined by Finnish soldiers during the Winter War in 1939. The name refers to Vyacheslav Molotov, who was the Soviet foreign minister at the time.

During the conflict, Molotov made radio broadcasts claiming that Soviet incendiary bombs were actually food deliveries for starving Finns. In response, the Finns mockingly called these bombs "Molotov bread baskets." When they developed the hand-held fire bottles to combat Soviet tanks, they called them "Molotov cocktails" as a joke. They suggested the cocktail was a drink to accompany the food parcels.

Historically, these weapons have appeared in several major conflicts. They were used for the first time in warfare during the Spanish Civil War between 1936 and 1939.

During World War II, many nations prepared them for combat. Finland refined the design significantly, even producing 542,104 bottles by the spring of 1940.

The Finnish military used a mixture of alcohol, kerosene, and tar, sometimes attaching wind-proof matches for reliability. Great Britain also prepared large numbers of petrol bombs through the Home Guard to defend against potential invasions.

More recently, volunteer units in Ukraine used them during the 2022 Russian invasion.

In military settings, the design can become quite sophisticated. The British War Office explored using white phosphorus as an ignition source. This led to the development of the Self-Igniting Phosphorus (SIP) grenade.

This device used a mixture of benzene, water, and rubber in a glass bottle. When the bottle broke, the phosphorus was exposed to the air and spontaneously ignited. Some models also used ballast, such as sand, to improve the accuracy of the throw. Other designs used an internal ampoule of chemicals that would break and ignite the fuel upon impact.

Because of their improvised nature, Molotov cocktails go by many different names globally. They are often called fire bombs, petrol bombs, or gasoline bombs. In some regions, they are known as "poor man's grenades" due to their low cost. In video games, players frequently use the abbreviation "Molly." Despite these many names, the core concept remains the same: using a simple, breakable container to deliver fire to a target. They represent a way for people to use basic chemistry and physics to face much larger, more complex machines like tanks.
