Today is Rubber Eraser Day, because on April 15, 1770, Joseph Priestly first discovered that scratching paper with rubber would remove any pencil marks from said paper. Little did Priestly know that his invention would not only enable the correcting and improving of all manner of written and drawn art, but would in fact become a medium in its own right. In tribute to Priestly, we present these 10 Inventive Rubber Erasers.
