How a Pencil Eraser Works — The Tiny Battle That Wipes Away Marks #science #pencil #eraser #how

Ever wondered how a pencil eraser really erases? It’s all microscopic: rubber is full of tiny adhesive molecules that, with a little heat from friction, grab graphite particles from paper fibers and lift them away. Repeated rubbing removes more marks while the eraser itself wears down as rubber transfers to the paper—a tiny battle of adhesion vs. friction that turns mistakes back into blank space.
