Amazing footage of an 11-year-old girl in China solving a Rubik's Cube one-handed underwater and breaking a world record in the process. <br /><br />The video, filmed in Xiamen, Fujian Province on April 8, shows Hong Jueyue and her master Ye Jiaxi attempting to solve the cube in under 45 seconds while underwater in a swimming pool. <br /><br />In the end, they took just 17.37 seconds to finish it and were awarded the world record. <br /><br />The pair have apparently been practicing for three months to take on the challenge.
