Rainbow Jello : 1 small box of jello for each color & 1 large tub of cool whip. Prep 1st color as directed using the quick chill method. Pour jello into glasses reserving about 1/3 of the liquid jello. Put glasses in the refrigerator & chill for 15-30 minutes or until slightly set. Mix about 1/3 cup of cool whip into the remaining jello. Pour the jello/cool whip mixture on top of the slightly set 1st jello already in the glasses. Repeat process for each color.
Rainbow Layered Jello. This reminds me of my mother's friend Gloria, who would make us red and green jello squares when we visited her at Christmas. Its that whitish foamy layer in between each color that really makes these different.
