No gang hear me out carbonated mustard I swear it's going to be the next big thing

The Sodastream people (bad company) sternly warn you not to put anything other than water into the carbonator lest you clog it up. The Drinkmate people (in beautiful Ann Arbor, Michigan) pretty much just say that carbonating any random stuff you found in the kitchen is fun and you should try it, their machine is really easy to clean (and if you really fuck up the valve it's a separate part, you can just buy a spare for $27)
