Join exhibit developer Charles Sowers as he demonstrates Watch Water Freeze, an exhibit designed to encourage noticing. Patience with this piece is rewarded with breathtaking patterns of ice crystals. Viewed through a polarizing filter, the beautiful colors and crystalline structures of Watch Water Freeze have inspired countless museum visitors to reach for their cameras. Exhibit developer Erik Thogersen backs away from the Giant Mirror. Watch his image change as he passes through the focal point, then continues on past the center of curvature. At the Giant Mirror, Senior Staff Scientist Paul Doherty demonstrates a simple way of locating a real image—an image that floats in space in front of the mirror. Senior Staff Scientist Thomas Humphrey invents a simple experiment to see if the Giant Mirror is spherical or parabolic, and then to see if it's perfectly spherical. By placing a Styrofoam ball at the center of curvature, he's able to prove that the mirror is out of pure sphericity by about one-quarter of one degree. Staff Neuroscientist Richard Brown demonstrates that the Giant Mirror reflects infrared radiation as well as visible light. Cheer on the competitors in this zany science cook-off. Teachers compete before a live audience at the Exploratorium for the revered title, "Iron Science Teacher." This week's secret ingredient: batteries. TI staff educator Eric Muller hits me up for change, and then demonstrates a neat science activity using dry ice.
