Walter Fred Morrison, like most other college kids in the 1930s, spent a great deal of time throwing around pie pans from the Frisbie Baking Company. But it wasn't until he joined the Air Force that he learned about aerodynamics and he realized he was doing science during those pan-flinging sessions.
So, Fred took what he learned about basic aerodynamics from the Air Force and made a prototype of a better flying disc, that didn't have bits of pie crust stuck to it. And instead of tin, he went with plastic. He dubbed his creation the "Pluto Platter," which was ultimately renamed the "Frisbee" and went on to provide hardcore leaping motivation for extreme college kids everywhere.
