The video, released on Wednesday February 12, 2014, has already been viewed over 8 times. It shows the duo (who together are OnTheRoofs), climbing the still under-construction Shanghai Tower. Upon its completion in 2014, it will stand approximately 632 metres (2,073 ft) high and will have 121 storeys. Following its topping out on 3 August 2013, it became the tallest building in China and the second-tallest in the world, surpassed only by the Burj Khalifa in the United Arab Emirates.
