This was inspiried by the original Big Dumb Russian. It uses Blue Curacao instead.Fill a 16-oz. pint glass with ice cubes. Add 2 oz of vodka then fill the glass to slightly more than 3/4 full with Sprite. Add pineapple juice to the glass then add enough blue curacao to give it a Caribbean ocean blue color.
