Mix each package with 1 cup boiling water. Divide each color into 2 cups. In one of the cups of each color, add 1 heaping tablespoon of sour cream. Place the 1/2 cup of plain red Jello in bottom of 5 cup Jello mold. Put in freezer until it is set. Then pour the cup of red mixed with sour cream over it and again put in freezer until set.
Follow this procedure with orange, lemon, lime and black cherry. You will have ten layers. When each color is set and you have it finished, refrigerate overnight. When you turn it out, it will look like a rainbow.
P.S. I find it works well in the Tupperware Jello mold as it comes out very easily.
