A Chinese artist, Cai Guoqiang, created a sparkling, mid-air ladder, lighting up the night sky one step at a time. A 80-second clip of the dazzling event has gone viral. Cai in his third attempt made the ladder to reach an impressive height of 1,650 feet in mid-air. Cai dedicated the 'Sky Ladder' to his grandmother, who recently celebrated her 100th birthday.
