English: Napalm is any of a number of flammable liquids used in warfare, often jellied gasoline. Napalm is actually the thickener in such liquids, which when mixed with gasoline makes a sticky incendiary gel. Developed by the U.S. in World War II by a team of Harvard chemists led by Louis Fieser, its name is a portmanteau of its original ingredients, coprecipitated aluminum salts of naphthenic and palmitic acids. These were added to the flammable substance to cause it to gel.
