1 1/2 oz of bacardi orange rum
1 1/2 oz of Bacardi Razz Rum (or raspberry-flavored rum)
4 oz of Cranberry Juice
1/2 oz of Pineapple Juice
1/2 oz of sprite soda
Pour ingredients over ice in a shaker. Shake and remove lid (carefully, sprite in glass makes contents under pressure-it has a tendancy to 'explode'). Pour into cocktail glass, garnish with Orange.
