overflowing airlock

[AlexMoran]

So I have a honey blonde ale in primary right now and the head has bubbled up into the airlock. I already cleaned it once, came back a half hour later and it was filled again. Should I just let it go or keep cleaning/refilling it with vodka?

These things happen on occasion. I find it's better to just remove the airlock and cover the hole with some tinfoil or plastic wrap during vigorous fermentation.

Would I be okay if I just left the airlock in and let it go?

It could cause an explosive situation and you will be repainting your ceiling. Best to take the airlock out and release the pressure.

This.

It is really cheap and easy to rig up. Trust me you'll only have an airlock blow once. Then you will always use a blow off tube.
