On August 24, 79 AD, Mt. Vesuvius in Pompeii, Italy exploded in a volcanic eruption. Tons of molten ash, pumice and sulfuric gas went miles into the atmosphere. In the 1800's, Archeologists were able to make casts of the bodies from the victims by filling the cavity with liquid plaster then carefully chipping away the lava, eventually to reveal a perfect cast of the body. Some people think these bodies are of "Petrified" humans, however they are NOT petrified.
