Guess Who Game with Elements

I was watching my kids play Guess Who today and I was thinking about an upcoming lab that we need to develop involving the elements when it dawned on me that one could do the Guess Who game with the elements.  I got excited about the idea, and then a family member found a very impressive version published by Natalie Gillis online at: http://mizgillis.blogspot.com/2013/01/guess-who-periodic-table.html .  Looks pretty cool!
