12 people participated in this experiment.  15 people were interested in this game.  This game has come a long way but I understand putting more questions in made the game more fun.  I also received feedback from the contestants to put more questions in so that way they have a better chance of getting point to win.  These kids were all grateful for participating and I gave them all jolly ranchers as a reward for participating but of course I did not tell them that they would receive jolly ranchers if they participated.  That would mean they only played the game for the candy so I rewarded them with candy afterwards.
