Rhythmic gymnastics is often one of those Olympic pursuits derided for not being a “real sport.” If you fall into this cynical camp, perhaps this clip of 14-year-old Boyanka Angelova will change your mind.

This footage of her performance at the junior championships has struck a chord with online viewers, being voted the number one clip on some popular video websites.

Perhaps it’s the way she can control her ball that’s drawn such praise. Perhaps it’s her flexibility that has folks in a tizz. Either way, this routine is pretty hypnotic.

It may not be the same kind of sport as a physical game of football or basketball, but there’s no denying the talent of this young gymnast.
