Seriously Matty, nobody is being a smart ass just to be a smartass. But a few days is nothing. Some airlocks will continue to show activity for weeks... usually because it is either still fermenting or CO2 is coming out of solution or like the good Rev said, "the cats bumped against it," or simply because the barometric temperature changed. What Revvy and Ryush are basically saying is that the airlock is not a fermentation gauge... it is just an airlock. Heck, some people have the opposite problem where the airlock shows no activity yet the beer is completely fermented. The airlock's only purpose is to allow gas to escape, but not to let crap in... thats all, nothing else. Always go by your hydrometer to gauge fermentation... not airlocks, not krausen, not the color, just the hydrometer. But I understand you are new and you have the new brewer jitters, but really, your beer is going to fine 99% of the time. If its at 1.010, your beer is fine... now let it sit for a week or two before botting or kegging...no matter what the airlock is doing (well I suppose if it starts talking to you, then you may reconsider). Your beer will appreciate your patience and reward you with 5 fgalllons of goodness!
