Sparkling water is a type of drink that refers to water which has been infused with carbon dioxide gas, resulting in small bubbles. This process creates a fizzy or effervescent effect and gives the water its characteristic sparkle. Sparkling water can be naturally occurring from underground springs or it can be artificially produced through methods such as forcing air through the liquid under pressure. It is often consumed as a healthy alternative to sugary sodas, sports drinks or other sweetened beverages and is popular for its refreshing taste and lack of calories.
