Neatorama is proud to be a co-sponsor of the latest How Did You Know? contest at mental_floss. You could win prizes from the Neato Shop, mental_floss, Motionbox, or Roku. It's a five-day trivia hunt, in which you'll be given a challenge each of the first four days. The answers will help you solve the big challenge for day five. However, you might win a prize just for playing, even if you never get any of them correct! Jump over to mental_floss for all the contest details, and start playing! Link
