Conclusion
         The hypothesis of which recipe would work the best was proven to be wrong.  Finger paint #1 worked the best.  This retained it's color the best, kept well, and felt the most like store bought finger paint.

         I believe that the corn starch  did not helped retain the color.  I believe this because finger paint #1 did not retain it's color well and it contained only water and corn starch.  While both finger paint #2 and #3 did retain their color well.

        I believe that recipe #2 did not work well because the starch needed something else to hold it with the water.  The two did not combined well. 
        Recipe #3 probably did not work well because of the laundry starch not thickening.  I don't know why it didn't but I may have been the wrong type  of laundry starch.  I believe that this was not a very good recipe to begin with.    I didn't like the idea of having soap of it because I had a feeling that it would get foamy lie it did.

        Recipe #1 worked well because it was mixed with both corn starch and gelatin which created a nice thickness and gelatin helps retain the color.

        I believe a way to improve the finger paint recipes is to make one that contained a smaller amount of corn starch than in recipe #1 and #2  and a higher amount of gelatin than in recipe #2 and #3.  I think this would help it smooth over the paper better and retain it's color.
