Sodastream is the ecological, economical, and fast way to enjoy handmade carbonated water whenever you want, wherever you are. The device uses a CO2 (carbon dioxide) bottle and adds carbonation to the water to turn it into carbonated water. You can use the device either for plain carbonated water, or by adding syrup to add flavor and turn it into a carbonated drink, or to create unique cocktails for you and your loved ones.
