fresh limes    lime sherbet    chilled Sprite (or other lemon-lime soda, you can even save on calories and use diet of Sprite Zero)    To make each float: Squeeze juice from 1/4 of a lime into a glass.  Then pour in some Sprite and top it off with a hefty scoop of sherbet.  You can also add some lime slices to the glass to make it look pretty.  It's that easy.  I might add some rum.
