    I keg my beer after fermenting hook up about 10-12 pounds CO2 into the Liquid side of the keg, set in the kegerator and forget it for a week or so. Comes out great. Today when I hooked the CO2 to the Liquid side as usual i heard it bubbling through the beer as it pressured up. Here is the NOOB observation... the keg pressured up but as I shook the keg around fitting it into the back corner, I heard more CO2 bubbling into the keg. So i shook around the keg, more bubbling . I did this several times , bubbling every time... Thus the reason everyone calls for pressuring up the keg and rolling it around for 5 minutes.

    Shaking causes more contact area between the beer and CO2. More contact area equals more mass transfer and solubility. Maybe you have a future in chemical engineering. :D

    I mostly surprised by the sound of how much was entering every time I gave the keg a shake.

    Yep agitating the cold beer under pressure allows the co2 to enter the liquid more redily. The colder the quicker.
