Here's an easy-ish one:I made 24 of these for my daughter's class recently. Buy vanilla pudding and prepare it according to the directions on the box. Split it into six seperate ziplock bags. Put a different food coloring into each bag, seal it and squish it around until it's all one color. Then squeeze each bag into clear plastic cups in layers to make a rainbow. Top it with a cool whip cloud. Easy and fun all in one!
