The slow dripping of water over limestone in Carlsbad Caverns forms some very strange rock formations over long periods of time. Drips of water running along the curve where wall meets ceiling form limestone "curtains," looking very much like cloth drapes made of stone. Tiny round stones called "cave pearls" accrete in the stagnant pools. Splattering water forms weird barnacle-like encrustations called "cave popcorn." When there is airflow, drips from the ceiling can form thin tubular straws, which bend to follow the gentle, constant flow of wind. These shapes lend an otherworldly quality to the caves, fantastical and surreal.
