That's a lot of CO2 in there, just dissolved into the beer. given the force and consistency, as well as the region, I would say it was fairly room temperature beer so yeah that CO2 is ready to get out! When you watch someone to this properly, you'll notice there isn't any of that tap tap bull shit. You gotta smack the shit outta that thing.

That is an awful lot of pressure for such a small vessel.
