Mexico's Record-Breaking Giant Crystal Cave

If you visit Naira, Mexico, you'll find the Giant Crystal Cave, also called the "Sistine Chapel of crystals." As its name suggests, the cave boasts the largest crystals ever found, measuring in at 12 meters long. It might sound like a natural wonder, but the cave's conditions are extremely hostile—hot, humid, and spike-y. Humans can only survive roughly 10 minutes unprotected in the cave. But, life has been found! In February 2017, scientists extracted long-dormant microbes from the crystals and revived them. Discover more about the Giant Crystal Cave in the following video, then learn more about peculiar caves.
