A Molotov cocktail is a simple incendiary device made from a glass bottle filled with flammable liquid, such as gasoline, and a cloth wick. When the bottle is thrown and breaks, the liquid ignites, creating a fireball. This type of weapon is often used in protests or riots due to its ease of construction and effectiveness. The name "Molotov cocktail" originated during World War II, named after Vyacheslav Molotov, a Soviet politician. It was used by Finnish soldiers against Soviet tanks during the Winter War. Today, it is often associated with guerrilla warfare and civil unrest.
