Which ingredient contributes to the carbonation in the mango cactus water?

The ingredient that contributes to the carbonation in the mango cactus water is soda water. Soda water, also known as sparkling water, is infused with carbon dioxide, which creates the bubbles and effervescence that provide the drink with its refreshing qualities. In a beverage like mango cactus water, soda water not only adds a fizzy texture but also serves to balance sweetness and acidity from other ingredients. While tequila, Monin (a flavored syrup), and lime juice contribute to the overall flavor profile, they do not have the ability to create carbonation. Therefore, soda water is the essential component that brings the fizzy element to this drink.
