Transcript of Make Me Care About Erasers

Creation
The eraser was created by an accident. Edward Nairne, the inventor of erasers, accidentally picked up a chunk of rubber instead of breadcrumbs to erase something, and it erased surprisingly well.
History
At first, people used a rolled up ball of bread without the crust to erase their writing. Then the erasers were invented. The eraser on the tip of the pencil wasn't thought of until Hyman Lipman created it for convenience.
High tech erasers are made out of vinyl, while most erasers you find on pencils are made out of rubber mixed with pumice to enhance it's ability to erase. Pumice, of course, is a volcanic rock!
Vocabulary
The erasers on the tip of your pencil is called a "plug".

The metal that contain the plugs are called ferrules.

Erasers are sometimes called "rubber" in other countries.
How It Works
Your eraser scratches the fibers in your paper, which cause them to loosen the graphite (the stuff in the pencil). The sticky rubber holds on to the graphite. The softeners in the eraser prevent the paper from tearing.
Fun Fact
The pumice combined with the rubber gives the eraser it's pinkness and smell. Originally the pinkness of erasers were just the result of it's ingredients, but now with new technology, erasers have new colors.

What It's Made Out Of

Vulcanization
When people first discovered that rubber could erase, they quickly learned that it would rot easily. So Charles Goodyear invented the process of vulcanization, where people add pumice in the creation of erasers to enhance its erasing ability and duRability.
