If a plastic eraser is placed in liquid nitrogen it will explode. The characteristics of explosion of the eraser were studied experimentally. The most probable cause of the explosion was cryopumping of a subsurface void. After boiling on the surface of the eraser, liquid nitrogen penetrates into the eraser and then flash evaporates in the subsurface void. A cryopumping model was proposed to capture the unique characteristics of the eraser frozen in liquid nitrogen.
