Create your own carbonated beverages with the Purefizz Soda Maker. It makes great-tasting soda pop... and much more! Add bubbles to water, fruit juice, wine, and even cocktails. There’s no limit to the possibilities. You add your favorite fruits, syrups or spices, and you control the level of carbonation. Simply fill the dishwasher safe, stainless steel bottle, close it with the stopper, insert a CO2 charger and shake. One charger makes 3 cups (.75 liters) of carbonated liquids. CO2 chargers required.
