Ok, it didn’t really fall out but the stopper with the airlock in it came loose for about 5 seconds when I hit it wrapping the Fermonster with a blanket. It was about half way in the hole so I just stuck it back in. First question is did that mess up anything? Second question, the airlock referenced above doesn’t have a nice flat open bottom where it goes in the stopper but has four small triangle openings on the bottom. I just Dremelled that thing small opening off of another 3 piece airlock I had and am going to do a quick replacement of the one that is in there now( of course after I sanitize the bejeesus out of it). I just don’t have any faith in those four small openings allowing it to do its job! Any thoughts on doing that?
