Will 1 of those little CO2 cartridges be enough to pour an entire corny keg full? I'm sure it isn't but I'm wondering how many times you'd have to change it during a party.
EDIT: Just read a description on another site and realized it will take 2 or 3 to empty 5 gallons. Maybe this is more trouble than just using my tank? I like the idea of not having the tank around for people to knock over though.
