Don't you sometimes daydream about inventing a simple, useful item — like the toothpick — and never having to work another day in your life? Well Carmela Vitale invented a simple, but essential tool for pizza lovers, the plastic piece in the middle of the pizza box that keeps the cheese from sticking to the top. 

According to Gizmodo.com, that circular plastic thing is called a pizza saver. And it was invented 30 years ago on February 10, 1983 when Carmela Vitale got her patent issued for that piece of plastic.That tiny little plastic invention has saved humanity from eating smushed and stripped pizza that has half of its cheese ripped off because the pizza got stuck to the cardboard top of the pizza box. Can you imagine eating that type of pizza? Without the pizza saver, delivery pizza as we know it would look more like blood and guts shmeared onto a giant bread thing. Does that sound appetizing to you? In the power ranking of necessary ingredients to a good pizza delivery, the pizza saver is probably right after cheese and before any topping.
