Morning Erasers!

Here’s something silly:

What do you think this image is?

Just take a wild guess..

Two sticks and a snack, right?

Or maybe you atleast figure the two sticks are writing utensils (they are).

But the piece of bread?

That’s an eraser..

The FIRST eraser to be exact!

But, HOW does an eraser… erase??

Well, let’s say you’ve written something –

AKA Graphite.

And PULLS the graphite off the paper fibers!

Leaving you all those rubber and graphite crumbs..
