Mastering the Law of Gravity.

I"m not fan of  martials arts films, but two months ago I saw a martial art movie named the last airbender, which like me so much. This movie was about a boy who was fifteen years old, he was the only one who could control the four elements: water, earth, fire and air, and keep the balance in the word.

In this movie I could see  how the boy manipulated the four elements and did others martials arts such as walked across the water, soar up walls and flew through the air....
