I enjoyed your quiz, wow, but I must take issue with the quizmongers regarding one of the answers. As to question #11, "Which way does water go down the drain, counter-or clockwise?" the correct answer is "either, regardless of the hemisphere you are in."

As summarized in The Straight Dope,

The boring truth is that water drains every which way no matter what hemisphere you're in, for reasons which have to do mostly with the shape of the drain, the way you poured in the water in the first place, and so on.
