When it comes to summertime refreshments, many debate the question: Which is better-sparkling water or lemonade? Sparkling-water
overs believe there is nothing more refreshing than water. They claim the flavor is simple and pure. On the other hand, lemonade lovers claim that
the tart lemon flavor quenches their thirst on hot summer days. Water drinkers claim that the sugar in lemonade just makes people thirstler. If you
really want to quench your thirst, unsweetened water is better. Those who can't decide just combine the two!
