Juggling geniuses

I read a TIME article today about a Russian brother and sister pair called Vova and Olga Galchenko. Vova is 18 years old and Olga is 15, and together they hold the world records for passing 10 clubs with 378 catches, 11 clubs with 152 catches and 12 clubs with 54 catches. Watch a video of them passing the clubs. They are amazing! Apparently, they make what they do look so effortless that they have to change their style to get more points for technical difficulty!
