A carbonated beverage maker includes a water reservoir, a carbon dioxide creation chamber, and a carbonation chamber. The water reservoir holds ice water and has a first impeller and a shroud surrounding the first impeller. The carbon dioxide creation chamber contains chemical elements and receives warm water. The chemical elements react with each other to create carbon dioxide when the warm water is introduced to the carbon dioxide creation chamber. The carbonation chamber is connected to the water reservoir and the carbon dioxide creation chamber. The carbonation chamber has a second impeller that includes a stem portion and blades. The stem portion and the blades define conduits therein. The blades create a low pressure region in a lower portion of the carbonation chamber such that carbon dioxide from the carbon dioxide creation chamber flows through the conduits to the low pressure region.
