Napalm

Summary

Napalm is an incendiary mixture of a gelling agent and a volatile petrochemical. The name is a portmanteau of two of the constituents of the original thickening and gelling agents: coprecipitated aluminium salts of naphthenic acid and palmitic acid. A team led by chemist Louis Fieser originally developed napalm for the US Chemical Warfare Service in 1942 in a secret laboratory at Harvard University. Of immediate first interest was its viability as an incendiary device to be used in American fire-bombing campaigns during World War II; its potential to be coherently projected into a solid stream that would carry for distance resulted in widespread adoption in infantry and tank-/boat-mounted flamethrowers as well.
