Yes, there's a glass slide on the side of a Los Angeles building. It's a unique way to get from the 70th floor to the 69th floor which hosts an open-air observation deck. "Clearly" these are impressive attractions when visiting DTLA (downtown Los Angeles), but OUE's Skyspace doesn't stop there. Well, rather the first stop is the 54th floor, where you can walk through sweeping video panoramas of the city of Angeles. Walk through the clouds, or as they say here, the marine layer. Also on the 54th floor are two seemingly simple amusement "stations." Step onto an infinity mirror that will make you feel like you're hovering over a bottomless hole. Then slide up to a vision of yourself made up of particles that follow your movements. Wave your arms until the particles float off into the air. This may be the closest you'll get to the Star Trek "Beam me up, Scottie" experience.
