What are the main ingredients in a fizzy drink?

The main ingredients in a fizzy drink typically include carbonated water, sweeteners (such as sugar or artificial sweeteners), flavorings (natural or artificial), and often citric acid or other acids for tartness. Some fizzy drinks may also contain preservatives, caffeine, or additional ingredients for specific flavors. The carbonation is achieved through the infusion of carbon dioxide gas, giving the drink its characteristic fizz.
