Frozen Watermelon

Directions

1. 1
   Line an 8-cup mold or mixing bowl completely with aluminum foil.
2. 2
   Working quickly, spread the vanilla ice cream 1 inch thick over the bottom and sides of the bowl. (It'll probably slide down the sides a bit.) Immediately place in the freezer and freeze for about 1 hour.
3. 3
   When the ice cream has become somewhat hard, but not frozen solid, spread it all the way up the sides to the top of the bowl; then replace it in the freezer for about 1 hour, until firm.
4. 4
   Place the raspberry sherbet in a medium-sized bowl and add the chocolate chips; blend until evenly mixed.
5. 5
   Place in the vanilla ice cream-lined bowl. Cover with plastic wrap and freeze overnight,or until completely hard.
6. 6
   When ready to serve, in a small bowl, mix the green food color with the whipped topping until evenly blended.
7. 7
   Remove the mold from the freezer, remove the plastic wrap, and invert onto a platter larger than the mold.
8. 8
   Remove the mold and peel off the foil.
9. 9
   Spread the whipped topping evenly over the ice cream and serve immediately, or freeze until the topping is firm, then cover and keep frozen until ready to serve.
