Shirley's Slush

1 46 oz can pineapple juice
2 quarts cranberry juice
4 cups sugar
2 cups water
2 liters of sprite

Mke 24 hours ahead of time. Boil sugar and water until dissolved. Add juices. Pour into shallow trays and freeze. I use 9 x 13 pans. When ready to serve, remove from freezer for 10 minutes and cut into cubes. Mash with a potato masher. Put in a punch bowl and pour 2 liters of Sprite into punch bowl. Usually need 2-4 liters of Sprite for one punch recipe.
