In two separate containers, freeze 16 ounces of orange juice and 16 ounces of pineapple juices (note: you can freeze a mixture of the two juices together in a mold for decorative purposes). In a punch bowl dissolve the gelatin and the sugar with the boiling water. Add cold water and the rest of the ingredients. When ready to serve, add soft sherbet, frozen juices and cold ginger ale. Stir well.
