Science East, housed in the former York County Jail, inspires interest in science, technology, engineering, and math through 150 exhibits and hands-on activities that kick start imaginations of all ages. Inside a building built with solid granite blocks, parents and kids step in front of a virtual wall to take turns interacting with a simulated ball before testing the limits of their peripheral vision at a reaction timer similar to those used during Formula 1–driver training. Hands guide a laser beam as it paints patterns across a disk, eyes peer into the faces and souls of exotic frogs and sticks tap across pipes to string notes into mellifluous melodies. Meanwhile, families venture down to the basement and enter jail cells lined with heavy barred doors that were used for 154 years to enclose prisoners. Visitors explore jail artifacts, learn about DNA at a forensic science exhibit and study displays highlighting the crimes of the prison's most notorious inmates. Meanwhile, fledgling scientists can stock up on essential equipment at the gift shop.
