Science on A Sphere (SOS)(R) March 20, 2010

Get an astronaut's-eye-view of Earth's surface as it changes minute to minute, by the hour, through the seasons, and over the years. Science on a Sphere creates stunning visual effects from real scientific data, and displays them on a six-foot-diameter globe. Three-dimensional video projectors show visitors such effects as the expanding wave pattern of a devastating tsunami, massive storms forming and moving over Earth's oceans and landmasses, and night lights around the globe that reveal our planet's most densely populated areas.
