Cellphones put the power of the world at our fingertips. With the touch of a finger, you can instantly connect with your doctor, have food delivered to your office, or simply obliterate your niece at *Words with Friends*. And it's all made possible by rocks formed millions of years ago, deep underground. Join us as we bust open our devices to figure out how these stones power our phones.
