Let's real 'er back in.
Not at all. It had a co2 bottle that screws in. Then you just screw one of the bottles on and press the button until it farts a couple times. The only major expense is the co2 refills, but they're not too bad and there's ways around having to get their branded bottles.
isn't there supposed to be a cap on the large end of the bottle? there is a grey one on mine and it has two holes in the bottom.. that doesn't seem like it will hold water in very well..
