"Napalm is flammable liquid used in warfare. It is a mixture of a gelling agent and petroleum or a similar fuel. It was initially used as an incendiary device against buildings and later primarily as an anti-personnel weapon, as it sticks to skin and causes severe burns when on fire. Napalm was developed in 1942 in a secret laboratory at Harvard University by a team led by chemist Louis Fieser. Its first recorded use was in the European theatre of war during World War II."@en . . .
