Paper Puzzle Idea
A few days before the party, take 12 pieces of normal paper and make a 4-3 array. Line the paper closely together. Take paint and make random designs and patterns on the papers, making sure the whole thing looks like one picture. Let it dry. After it dries, take a phone or camera and take a picture of the whole puzzle.
The day of the party, print out a picture of the puzzle. Take the puzzle, scramble it up and put it at the end of your driveway. Take chalk and make a very noticeable line on your drive way about five yards away from the pile of paper.
Have your guests, one by one, crab walk over to the pile, take one paper, and sprint back and start another pile. When all the papers are gone, give them the printed out picture of the puzzle and have them make the puzzle. This is a good game for teams, the fastest team wins - a real survivor style game!
