Quick, grab as many basketballs as you can and see if you could possibly juggle them. Now flip over and do it upside down, using your feet to juggle a few.
Sounds impossible right? Well it is for everyone except this girl.
David Calvo has a unique talent, a talent that will do him no good later in life, but will make him a Youtube star today.
He can juggle Rubik's Cubes and solve them at the same time. That's right, I said AT THE SAME TIME!
While this is a cool trick, all I can't help but wonder when he decided that he wanted to learn how to do this.
