Ariane Szu-Tu is an editor at National Geographic Kids, and she called in for a chat about their latest book, Bet You Didn't Know! 2: Outrageous, Awesome, Out-of-This-World Facts.  It's a fun book full of colorful illustrations and fascinating fun facts.  I learned why my Batman shirt may be the reason I didn't do as well on my exams as I should have.  I also got the true reason why an entire section on pizza facts had no mention of Chicago.
