By Olivia Williams PUBLISHED: 14:40 EST, 13 March 2013 | UPDATED: 03:12 EST, 14 March 2013 On course to become a world record breaker, 14-year-old Lee Norton can already stack and unstack cups faster than anyone else in Britain. Lee, from Waltham Cross in Hertfordshire, is the national sport stacking champion, a speed game in which competitors build plastic cups in a pyramid formation and take them down as fast as they can. He has become an internet sensation, clocking up more than 500,000 hits on YouTube with his record attempts and tutorials. Lee is so keen to work for the world title that his parents have to make him cut down on practice so he can finish his homework.
