Basically you fill a bottle with water, push a button to carbonate it, then add the syrup of the flavor of pop you want. We are hooked!
The first time we used it, it wasn't quite fizzy enough - - turns out we weren't putting enough in. Now we're pros and over-fizz if anything. You're supposed to push the button until you hear the buzz - it's a real buzz, so wait for that. I made a video of some newbies (every time someone comes over we say "hey, let's show them how to make pop!" - it's great fun!). You can see how the kids LOVE this!!
Flavors - the possibilities are endless! My favorite is the Pink Grapefruit - it's got a kick I love. Or maybe the Cranberry Raspberry... I can't decide!
