If you have time, place the Hawaiian Punch and lemon-lime soda in the refrigerator overnight to cool. For this recipe, the ratio of Hawaiian Punch to lemon-lime soda is half and half. The exact proportions depend on the the size of your container or punch bowl.
Fill up your container halfway with Hawaiian Punch.
Then fill up the rest of the container with lemon-lime soda (no need to stir).
If your soda and Hawaiian Punch aren't already cold, you'll need to pop the container in the fridge to cool.
Or serve over ice. Then add in a Swedish fish for a special touch.
