Use the SodaStream Spirit to turn regular tap water into sparkling water. First, you fill the included bottle with water. Turn it into sparkling water by adding carbon dioxide with a push of the button. You can decide the level of intensity of your sparkling water. If you push the button more often, you add more carbon dioxide, which means the water will become even more sparkling. This way, you can make light sparking water and more intense sparkling water. Would you like to add a flavor? Do this after you've added the carbon dioxide. When your sparkling water is done, you put the cap on the bottle and take it with you on the go. Or you can store it in the fridge and enjoy it later.
