In front of each bag is a turtle. There is a blue shelled turtle, a red shelled turtle, and a turtle whose shell is blue and red. The Bard says, "Inside these bags are gems. There is a bag of red gems, a bag of blue gems, and a bag of mixed gems (red and blue). Each turtle has a shell color that corresponds with the gems in the bag. However, each turtle is currently in front of the wrong bag."One turtle then speaks out, "You are allowed to pull out 1 gem (from any bag), look at it's color, then put it back into the same bag. Then you must rearrange us so that our shells match the correct bag with the same colored gems. Do this and you may keep any bag you want. Only 1 gem may be pulled out (total). Now stop looking at me like that, you're freakin' me out."How do you do it?=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=Pull a gem out of the mixed shell's bag.  We know it isn't the mixed color gem bag, because then the right turtle would be in fron of the right bag.  So whatever color the gem is (say blue), that turtle (the blue one) should be moved in front of the bag where the mixed color turtle was.  The remaining pure color turtle (red in this case) has to go where the first pure color turtle (blue) was, because if you just swap mixed color for blue, then red would be left sitting in fron of a red bag, which would mean he was in the right place from the start.  So blue goes where mixed was, red goes where blue was, and mixed goes where red was.  Swap that chain if you pick a red gem,</blockquote>
