Seeing: 30 Hands-On Visual Discoveries by the Exploratorium

Is that smile real or fake? Can you make an image of a light bulb appear actually to glow? Witness illusions like the "floating hot dog" or the "hole in hand," play with anamorphic mirror images, and turn 2-D stereogram designs into 3-D to find a hidden picture. This book of hands and eyes-on activities—a total of 30—is based on popular Exploratorium originated exhibits. Great for keeping young minds busy during long road trips and older memories happy with the brain and vision exercises. Softcover, 30 pages.
