Napalm

Napalm is an incendiary mixture of a gelling agent and a volatile petrochemical (usually gasoline (petrol) or diesel fuel). Napalm was originally developed in 1942 in a secret laboratory at Harvard University. Napalm burns at the same temperature as gasoline, and for a greater duration, as well as being more easily dispersed and sticking tenaciously to its targets; these traits make it extremely effective (and controversial) in the anti-structure and antipersonnel role.
