Newton's Unintentional Invention

Newton could not shut the door since the cat would meow and scratch. His solution was to cut a small hole at the bottom of the door and place a piece of fabric to cover it. In this way, the cat could come and go at will. The cat flap has since evolved. We now have electronic chips sewn into animal collars that will only permit entrance to your pet.
