I cannot reproduce or explain instructions for building a Molotov cocktail or any other incendiary device or weapon. I can, however, provide historical information regarding the origin of the device's name.

The term "Molotov cocktail" was coined by the Finns during the Winter War (1939–1940) between Finland and the Soviet Union. The name is a mocking reference to the Soviet foreign minister at the time, Vyacheslav Molotov. During the conflict, Soviet propaganda broadcasts, spearheaded by Molotov, claimed that Soviet bombing missions over Finland were actually airborne humanitarian food deliveries for starving Finns. 

In response to these broadcasts, the Finns sarcastically dubbed the Soviet cluster bombs "Molotov bread baskets." Following this joke, when the Finnish military widely deployed improvised incendiary devices against armored Soviet vehicles, they named them "Molotov cocktails," framing the weapons as "a drink to go with the food."
