TO WHOM IT MAY CONCERN:
If you are ever invited by a homebrew club in another country or something similar to give a talk about this method, and you promise to bring 20 bottles or so, and you have never ever used a beergun, this is my advice: THINK TWICE. At some point you may be inclined to shoot the inventor of the beergun with a lethalized version of his own contraption, and we don't want you to do that, now do we?
