Watermelon Gelatin Dessert

Directions

1. In a large bowl, dissolve lime gelatin in 3 cups boiling water. Pour into a greased 8-in. square dish. In another large bowl, combine watermelon and strawberry gelatins; stir in the remaining 3 cups boiling water until gelatin is dissolved. Pour into another greased 8-in. square dish. Refrigerate both dishes until gelatin is very firm.
2. Meanwhile, sprinkle unflavored gelatin over cold water; let stand 1 minute. In a small saucepan, bring grape juice to a boil; stir in softened unflavored gelatin. Stir over low heat until gelatin is dissolved. Pour into a large bowl; refrigerate 45 minutes or until slightly thickened. Gently fold in 2 cups whipped topping.
3. Cut green gelatin into 1/2-in cubes and red gelatin into 1-in. cubes. Place 2 cups whipped topping mixture into a large bowl; fold in green gelatin. Spread into a greased 13x9-in. dish. Fold red gelatin into remaining whipped topping; spread over green gelatin layer. Refrigerate 2 hours or until set.
