Jellypet (short for Jellied Petrol) is a thickening/gelling agent generally mixed with petroleum or a similar fuel for use in an incendiary device, initially against buildings and later primarily as an anti-personnel weapon. Colloquially, jellypet has been used as the generic name of several forms of jellied gasoline used in warfare, such as to be expelled by flamethrowers in infantry and armored warfare.

Jellypet is what napalm is called in AAO.
