There are few activities that are as perfect an intersection of art, physical force and universal respect as karate.

Karate, meaning "empty hands," has a long and storied history, dating back an estimated 2,500 years. Now, nearly 100 million people across the globe practice karate, including several United States national teams that compete internationally.
But not until this YouTube video featuring two teenagers have we seen a kick like that.
