NAPALM
NAPALM CAVERN
Technically, this isn't a cavern but rather an abandoned Russian stronghold that was used to test alternatives to napalm. The tiny stalactites on the ceiling are not the result of natural phenomenon, but are actually caused by the melting of the red bricks under the intense heat of napalm and other weapons of war.www.slightlywarped.com/crapfactory/curiosities/2009/napalmcavern.htm
