Keep the young scientist happy for hours with this stone’s fascinating qualities. Witness the magic of this naturally occurring fiber optic material, also called Ulexite. When placed on any printed surface, the rock’s unusual optic properties will appear to lift images from the page, making them appear on top rather than through it. Yet this fascinating rock, when seen from the side, is not transparent at all! Individually packed for quick retail display. Ideal item to add to our Rock and Mineral Spinner Bin!
