Mix the pina colada with 2 1/2 ounces of Bacardi rum with ice and set aside. Next mix the strawberry daiquiri with 2 1/2 ounces of Bacardi rum with ice. While frozen, add the pina colada mix to a cocktail glass. Add the strawberry daiquiri mix on top, keeping it separated from the pina colada mix. Insert a straw, and give it a swirl to create a swirl effect. Enjoy!
