In Lg. (10 oz) tumbler, mix smirnoff watermelon vodka, watermelon pucker and red bull energy drink. Serve chilled or over ice. We have found the ideal flavors to be Watermelon, Green Apple, Strawberry or Raspberry Vodka in combination with the same flavor of Pucker. You may also pre-mix the drink by combining 1 Bottle of Vodka with 1 Bottle of Pucker and kept refrigerated. Then just fill your glass with Red Bull and mix as needed. Much more convenient!
