Gonna try this one. It may require the addition of rum, though.

PINEAPPLE COOLER
4 cups unsweetened pineapple juice
2 teaspoons lemon juice
1 teaspoon vanilla extract
1/2 teaspoon coconut extract
2 cups carbonated water

In a pitcher, combine the pineapple juice, lemon juice and extracts; chill. Just before serving, stir in carbonated water. Serve over ice.
Yield: 3 servings.

Now that sounds good!!

OH YEAH...THE RUM...THESE WILL DEFINITELY MAKE YOU FORGET THE HEAT....
AND ANYTHING ELSE THATS GOT YOUR KNICKERS IN A KNOT!!!

That does sound yummy, Im going to have to try it!!
