The bizarre patterns at Avshalom Cave combined with the ghostly lightening creates a rather creepy ambience inside the cave.
Given enough time these tiny layers add up to form columns of calcium carbonate called stalactites and stalagmites.
This process that turns the water acidic is called Karst and helped with the cave expansion process.
The cave is named after Avshalom Shoham, an Israeli soldier killed in the War of Attrition.
