Funnel the lime juice, grapefruit juice, maraschino liqueur and water into a flask. Cap the flask tightly, then set it in the freezer at 45-degree angle and freeze for at least 3 hours. Decant the rum in another container separately.
When ready to drink, open the flask and pour in the rum using a funnel. Shake vigorously until all of the ice has melted.
