Airlock fell out

[abciximab]

So, I have a batch that's been in the fermenter for a couple months. My wife knocked the airlock off so the beer was slightly open to air for a few hours. I'm guessing this isn't a big deal, but just wanted to check.
Thanks!

No biggie. Clean, sanitize and put back on.

Thank you!

How did she do that without breaking it?

 

[abciximab]

Good question! She tried to put it back, but she put it into an empty carboy...

Couple of months? What are you brewing?

Unless you have problems with those pesky fruit flies, I always felt the small hole for the grommet would keep most nasties from settling downward into the fermenter.
