I just went trough this.
Got 2 consecutive FG readings of 1.014....so I plopped in 4oz (Simcoe and Amarillo) pellets just to have the airlock get all going crazy again....
I was like "that's cool...just gotta be the beer playing with the hops" - and it was, the airlock stopped after a day or so.
BUT, the damn hops kept floating up and down....up and down....up and down - and would not stop. If I slightly touched the carboy it was like mini eruption of hops blowing out of the trub..
So after 7 days it was time (actually my only opportunity) to bottle, but all those hops were being rambunctious - urgh.
I did not want all that in my beer so I went to the store and picked up some knee high pantyhose. Sanitized those, along with my siphon/racking stuff and attached to end of hose with sanitized rubber band.
Racked off the carboy into bottling bucket keeping the hose under the beer and low-and-behold - the dang pantyhose caught A LOT of those acrobatic hops.
In a couple week I get to see how my IPA turned out
