A carbonator is a device that adds carbon dioxide gas to liquids, creating carbonation. This process results in fizzy drinks, such as soda and sparkling water. Carbonators can be found in various forms, from large industrial machines used in beverage production to smaller home devices designed for personal use. Home carbonators allow users to carbonate water or other beverages easily. They typically consist of a CO2 tank, a carbonation bottle, and a mechanism to release the gas into the liquid. Popular brands, like SodaStream, have made it convenient for consumers to enjoy homemade carbonated drinks without the need for store-bought options.
