Old Woman Chews on Glass and Stones

A 63-year-old Chinese woman, Chen Fengzhi, is well-known for chewing up glass and stones with her “iron teeth”. In this video, she shows her special trick by smashing a light bulb and chewing the pieces of glass. After swallowing the glass, she goes on to pick up a small stone and bite down hard on it. This kind of skill is obviously not for everyone. Credit: YouTube/Jianqiang Zhou
