Drip stone, also known as stalactites, are pointed formations of mineral deposits that hang from the roof of a cave or underground erosion of rock formations. There are several other synonyms for drip stone such as icicles, stalactites, or rock pendants, all of which refer to the similarly shaped formations. These natural wonders are formed by the slow dripping of water that contains dissolved minerals, which eventually harden and accumulate over time. Drip stones can come in various shapes, sizes, and colors, depending on the type of minerals present in the water that drips through the cave. These formations are not only beautiful, but they also provide important geological and environmental information for scientists and researchers.
