A 12-year-old boy from China is going viral on the Internet for solving three Rubik’s cubes simultaneously while juggling them.

News site Shanghaiist posted a video of the astounding feat by Que Jianyu on its Facebook page on Monday (9 April). The video has been viewed more than 6 million times.

The prodigy performed the task last December on the television show iDream of China, setting a Guinness World Record for taking the shortest time to solve three Rubik’s cubes while juggling. His timing was 5 minutes and 6 seconds.

Que, who lives in Xiamen in Fujian province, regularly appears on television shows to display his incredible skills with the puzzle, which requires one to twist and turn a cube until all the squares on each face are of the same colour.

Other feats he has achieved include solving three cubes with his hands and feet at the same time, and solving one cube while blindfolded after memorising the positions of all the squares.
