A Molotov cocktail consists of a glass bottle partly filled with a flammable liquid. The liquid will typically be gasoline, alcohol, methanol or ethanol. The mouth of the bottle is closed with a cork or other type of tight sealing made of rubber, glass, or plastic, and a cloth rag is fixed securely around the mouth. The weapon is used by first soaking the rag in a flammable liquid immediately before using it, lighting the rag, and throwing the bottle at the target. The bottle breaks when it lands, spilling the flammable liquid over the target, which is then ignited by the burning rag.
