Place your TV rock on any printed surface and watch how the tiny fibers transmit the image to the top of the rock. This unusual effect is the result of ulexites amazing fiber optic properties. Try placing your rock on an actual TV screen, a photograph or a leaf. You’ll see the same effect. Get them while they last!
