The new glass side on the exterior of a Los Angeles skyscraper was filmed being tested out by thrill-seekers on the 70th floor. 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. The riders can be heard screaming on the slide despite their distance from the camera. The slide, part of the tower’s $50 million Skyspace renovation project, opened to the public officially on Saturday. SkySlide is made of three-ply glass, 1.25 inches thick, made to withstand hurricane-force winds of up to 110 miles per hour. It hovers 1,000 feet above the pavement.
