The Science Mine, 36 E. Granite St., will be open 10:00 am to 2:00 pm on Saturday. Build your very own landscape at the Augmented Reality sandbox with real-time elevations by color, topographic contour lines, and simulated water! Join us for hands-on learning and sensory exploration. Enjoy new exhibits - the telephone switch - and good old favorites including the Bernoulli Blower, Gaussian Gun, and more.
