Bubbles 101: Carbonating cylinders create the bubbles.
Exchanges replace empty carbonating cylinders with new ones.
You can easily exchange your carbonating cylinder via home delivery https://sodastream.com/pages/get-a-refill, or at a store near you https://sodastream.com/pages/store-locator/
Back up carbonating cylinders are there for you when you need it most - so that you never run out of bubbles.
We recommend you sparkle smarter by always having a back up carbonating cylinder ready in the comfort of your home to avoid SOS situations (Save Our Sparkle!).
Check out our Out of Gas guide below for further instruction on getting back to bubbling.
