With the SodaStream TERRA Black, you can make your own sparkling water with one push of a button. You can easily add carbon dioxide to the water via the large button on the top. The more you press the button, the more bubbles you add. You can adjust the amount of carbon dioxide to your liking. The bottle you make the sparkling water in, is reusable. That's why you don't use as much plastic anymore and you're more environmentally-friendly. The SodaStream also includes a CO2 cylinder that you can use to make about 60L of sparkling water. Thanks to the Quick Connect technology, you can easily click the cylinder into the machine. You can clean the reusable bottle in the dishwasher after use.
