You don't have to be a Kungfu master to smash a brick using your bare hands.
All you need is a basic grasp of the momentum theorem, according to Huo Lingyu, a physics teacher at Zhengzhou No. 101 Middle School.
In a video, to illustrate the momentum theorem, Huo Lingyu is seen placing a brick on the edge of a table and splitting the brick in half with his right hand during a physics class. The students surrounding him let out cries of amazement after he performs the stunt.
