The Rainbow fits well in a 9x13 pan. Then pick 6 boxes of your favorite Jello. These are the ones that I picked but you can pick whatever ones you like.
1 (3 oz.) box Strawberry Jello
1 (3 oz.) box Orange Jello
1 (3 oz.) box Pineapple Jello
1 (3 oz.) box Lime Jello
1 (3 oz.) box Blueberry Jello
1 (3 0z.) box Grape Jello
1 pt. Sour Cream (2 cups)
Step One: Take 1 box of Jello (I started with Grape but you can do whatever you would like.) and 1 cup of boiling water and mix together until dissolved.
Step Two: Then measure out 1/2 cup of the Jello mixture into another bowl and add 1/3 cup of sour cream and mix together. Pour into the 9x13 pan and set in the refrigerator until set, about 20 mins. Make sure that your pan is level in the refrigerator.
Step Three: Then mix 3T of Cold Water in with the remaining Jello mixture and pour over the firm sour cream mixture. Let firm. Repeat 5 more times alternating cloudy cream mixture with clear Jello mixture until done !
I used whipping cream for the cloud and Gold coins or Rolo's for the gold.
HAPPY ST. PATRICK'S DAY!
