Lime Slush

6 oz. pkg. lime gelatin
2 cups boiling water
2 cups cold water
46 ounce large can pineapple juice
1/4 cup lemon juice
1 cup sugar

Dissolve jello in boiling water and then add the cold water, pineapple juice, lemon juice and sugar.  Freeze to a slush, stirring every few hours.  If you do not stir the slush it will freeze up to firm and be more like a lime ice cube. You need to add air to it so you can spoon it out later.
Spoon into glasses and serve with 7-up or any other lemon lime
