I came across this YouTube awhile ago. The FizzGiz starter kit starts at $49. I haven't tried it. The caps they provide fit onto most regular sized 16 oz. soda bottles (and probably bigger plastic bottles). Besides restoring carbonation to soda pop that has gone flat, you can supposedly use this gadget to infuse marinade into meats in a fraction of the time compared to marinating in a bag or bowl. I'm highly tempted to try it as I sometimes don't want to wait hours for the marinade to absorb into meats. Anyways...
