A soda maker is a kitchen appliance that allows users to create carbonated beverages at home. It works by infusing water with carbon dioxide gas, producing fizzy drinks. Many soda makers come with reusable bottles and can be used to make flavored sodas by adding syrups or fruit. These devices are popular for their convenience and ability to customize drinks. Users can control the level of carbonation and experiment with different flavors, making it a fun option for families and individuals who enjoy fizzy beverages without the need to purchase pre-made sodas.
