Story Behind the Invention

Inventor Angela Harris of San Diego, CA has developed a graphite laced erasable liquid that liquifies with the consistency of a number 2 pencil and allows you to fill in circles more easily. Ideal for standardized testing, voting, lottery cards, or anything with a scantron-like application, the invention is ready to hit the market!

As a teacher who had to take attendance on a scantron-style form, Angela realized it took forever! She just knew there had to be a better way. In turn, she was inspired to create an erasable substance that would work like a dauber and forever change the way forms are filled out. The Liquid Eraser is her solution.

But how does it work? This soluble can be adapted to an existing pen-like instrument. With one motion of the dauber, repetitive circling typically done with a standard pencil has been eliminated. When the dauber is applied to a writing surface, it provides for a machine-readable pattern. The composition may be erased using a standard pencil eraser and remarked if necessary.
