Improvised Blow Off Tube

The quad is fermenting away nicely, and I was just thinking how smoothly everything’s going.  The brew went well and we hit our gravity right on the mark.  In fact, it went a little too well and we wound up with a little more than 5 gallons, but we figured there was enough head space in the fermenter, so why not keep it?

Now fermentation has started, and is going perhaps a bit too briskly — foaming up out the airlock and gumming it up.  I just cleaned out the airlock and two minutes later it was all gunky again.  So I rigged up a blow off tube.  Luckily, our normal tubing we use for siphoning is the same gauge as our airlock stem, so I just plugged it into the airlock hole and put the other end in a half-full gallon growler.  It’s bubbling very musically every minute or so.
