Double dose of tricks to impress your friends (and possibly win bets)

(CBS News) We have done a few posts now displaying 10 tricks each that you can use to impress friends (or win bets with) using a bit of logic and science. So I figure why not give you a double dose this time starting with the video above to up your arsenal with an additional 20 new tricks.

The fantastic videos are all done by Richard Wiseman (aka Quirkology), whom we've posted about previously here, here and here, and who continues to amaze us all here at The Feed with this combination of educational and fun series. We're including another recent video below entitled "10 Amazing Science Stunts For Parties".
