rubber can erase pencil, was first discovered by the British scientist Priestley in 1770. Prior to this, people use sponge to erase the pencil. Sponge body is small, and soft, and flexible, with its water absorption is very good, but use it to wipe the pencil, but can not make people satisfied.

Priestley the discovery caused a sensation, because it brings people great convenience. But the earliest rubber is made of natural rubber, rub the word do not fall into the debris, but the end of the pencil on the rubber, the more the more dirty. Later, people in the production of rubber, the addition of sulfur and oil and other substances, so that the rubber is very easy to fall off, the end of the pencil is erased with the debris left the rubber, so that the rubber can often keep clean, it will not be soiled.

1, can wipe away the pencil marks, modify the typo, now some can wipe pen marks.

2, some of the rubber is very beautiful, can be used as a gift or craft.

3, can also wipe the shoes, cars and other things on the criminal road.

pencil eraser's handwriting, in fact, is the rubber of the pencil to write on paper writing (by a pencil powder composition) adsorption is gone. As long as the eraser, along the rubber "footprint" of the pencil is gone, that is, the rubber on the adsorption of the pencil powder, more than the paper on the adsorption of pencil powder. When writing with a pen, the surface of the paper is to be a little bit of a little bit of the internal writing (ink), and in the rubber to be equipped with a hard fine powder. The rubber works like a file, but with an eraser off pencil marks is the action of the force of friction and produce the phenomenon of
