Stir together cranberry watermelon juice and vodka. Pour into 5 frozen pop molds (2.5 ounces to 3 ounces each). Cover, insert straws or craft sticks, and freeze for 8 hours or until completely firm. To serve, dip outsides of molds into warm water to loosen. Makes 5 pops. Tip: No popsicle molds? No problem. Pour mixture into 4- to 5-ounce disposable paper cups. Cover cups with foil. Place flat craft stick into center of each pop. Freeze as directed. To unmold, peel paper away from pop.
