So I happened to be standing around, eating a bag of vanilla wafers when my friend drove by. Not thinking twice, I grabbed one and threw it at her car. What happened next was nothing short of extraordinary. It flew in a straight path for about 150 feet (although it missed her car)!
I'd never really thought about it, but a vanilla wafer is shaped like a round airfoil.. i.e. like a frisbee. If you can get it to spin rapidly and stable enough in a horizontal plane, it will generate lift depending on how fast you throw it. Try it at an upwards angle! Don't throw it like a frisbee, wrap your index finger around it and throw sidearm, letting it roll off at the end.
Just thought ya'd like to know
