ACID CAVES EXPLORED science documentary DVD Nature’s Chemical Wonder
$ 17.96
Description
This is “Nature's Chemical Wonder: Acid Caves Explored,” a previously-viewed DVD in its original plastic clamshell case with art. It is a retired library edition with the usual stickers and marks of former ownership. Created by TMW Media Group in 2012, the disc is in great shape and plays perfectly (double-checked). From the back: “Deep in Southern Mexico's jungle, the Villa Luz limestone caves support an ecosystem that thrives in a highly poisonous, acidic environment. This rare type of cave is found in few spots on Earth. The Villa Luz is known for the bacteria in its thermal sulphur springs that produce hydrogen sulfide gas. When the gases form bonds with oxygen, the result is sulfuric acid. The acid eats away at the cave walls, constantly altering the patterns in the cretaceous limestone.” Powered by SixBit's eCommerce Solution
