While finishing Math yesterday The Student wanted to know: "Why are erasers pink?"
After a google search we found the following answer on ehow.com.
History
The
beginnings of the modern eraser are traced to 1770, when Edward
Nairne sold cubes of natural rubber from his shop in London. The pink
eraser became common when Eberhard Faber began to manufacture the
Pink Pearl in a factory he started in 1861.
Properties
Pumice,
a type of volcanic rock, and organic rubber were combined to make the
pink eraser. This combination created the distinct smell and color of
the eraser.
Features
The
pumice gives the pink eraser its abrasive quality without detracting
from the softness of the rubber.
Function
Erasers
are used to remove markings from surfaces, most often to remove
pencil markings
from paper.
Fun
Fact
Papermate
reported the sale of 132,000 Pink Pearl block erasers in 2008.
