Okay, we have taken this thread far enough.

High Chief, you'd do best to listen to the advice being offered instead of flaming people who aren't giving the answer which you OBVIOUSLY wanted to hear which would have been, "WOW! High Chief! You are a genius! No one has ever thought of using pre-packaged CO2 from the sporting goods shop before!!! OMG!!!1!!!"

Thread CLOSED. Take the good advice and RELAX.
