The 45-foot-long glass slide, which takes riders from the 70th floor to the 69th floor on the outside of the U.S. Bank Tower, hosted its first test-riders Saturday and the thrills were caught on camera by Sterling Davis, who filmed the slide from a neighboring building and posted the video to YouTube.
