How many times do we have to say it?  Airlock activity is not a good indicator of yeast activity.  Check your gravity before you worry about what the yeast is doing.

i actually hadn't heard that, so thanks.

what about other than airlock activity, like this....

Sorry, I just assume everyone reads everything :)

Sure, in the video you can see the yeast is doing something.  Airlock activity is just gas coming out of solution, maybe because the yeast is generating more, maybe because of temperature changes, maybe because it hasn't reached equilibrium yet.  One bubble every 25s could be any of those things, mine will bubble that fast or faster long after the beer has reached terminal gravity.  Even every 8s doesn't tell you much.  That's not to say you should ignore the airlock in these cases, but if it slows down then the yeast is done or nearly done.  Check gravity, wait a couple of days, check it again.  That will tell you what is going on.

thanks tom!
