A Chinese teenager -- who already holds two Guinness World Records -- broke two more by solving three Rubik's cubes at once. Xiamen resident Que Jianyu solved three rubik's cubes at once, one in each hand and one with his feet in one minute and 36.39 seconds. Que then suspended himself from a bar and broke the record for fastest time to solve a Rubik's cube upside-down, finishing with a time of 15.84 seconds, 1.6 seconds faster than the previous record holder. Que previously broke Guinness World Records for fastest time to solve three Rubik's cubes while juggling and fastest time to solve a Rubik's cube by a team of two. Que told Guinness officials, "For beginners, it may look much difficult to achieve these records. At first, I solved the cube's by using the formulas, after million times of practice I was familiar with all the logic of the formulas and then I upgrade them to my own way."
