I was reading this article about how the widget works in guinness bottles. http://recipes.howstuffworks.com/question446.htm
If this is really how the widget works, couldnt home brewers just repeat the process...Fill a guinness bottle with beer. Add liquid nitrogen to the bottle. and cap it? Obviously the trouble lies in getting the liquid nitrogen, but is that the general idea of the whole process? Probably a stupid question, but I am bored at work and my brain wheels are turning.
