Why Are Pizza Boxes Angular
Did you ever spent a thought on why pizza packages are angular and not round like the pizza? Because you should use the carton like a bib. Put the pizza box on your lap. Now open the box and put the cover on your breast like a bib.
This is an easy way to protect your clothes from grease spots and leftovers. If the pizza package would be round there would always be a risk that the dirt would fall next to it right on your outfit.
