Bubbles 101: gas cylinders create the bubbles.
Exchanges replace empty gas cylinders with new ones. You can easily exchange your carbonating cylinder via scheduled home delivery (click here), or at a store near you (click here to search for a nearby store).
Back up gas 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!).
