Thank you, I have used that sort of circle game when I was teaching history. I like that idea. I was just explaining it to my wife who teaches third grade, she's going to use it.
And wouldn't it be cool in a few years when they are of legal drinking age for them to grab that ping pong ball and think "Damn, Tex was preparing me for life in college, just like he promised!" I was trying to present it as more of Bozo's Grand Prize Game or a carnival midway game.
