Juggling, and solving a Rubik's Cube, can be impossible tasks on their own, let alone at the same time.

But a Stanford student known as Sir Ravi the Juggler can do both at once without appearing to break a sweat.

The Rubik's Cube has been the bane of many, with more than 350 million sold worldwide since its release in 1980.
