Water dripping down a stalactite

Videonummer 12591077
Close-up of water dripping down a stalactite in a cave. Stalactites are protrusions of rock from the ceiling of a cave. They form as mineral-rich water drips down through the porous rock, each drop leaving behind a tiny bit of its dissolved minerals. Over many years the minerals form long icicle-like formations. Below the stalactites, the dripping water can form similar structures rising from the ground, known as stalagmites. In some cases the two may meet to form a column. These features are common in karst regions, with an underlying bedrock of limestone. Limestone is soluble in slightly acidic water, leading to the formation of extensive cave systems
