Fill the Bubbler Airlock with water and insert in drilled stopper or bung to vent gases during fermentation.
"Bubbler" style airlock makes a gratifying "bloop" noise during active fermentation. It is the preferred airlock for secondary fermentation, as it is possible to monitor the pressure inside the fermenter.
To use: Insert assembled airlock into the hole of the rubber stopper that fits your current jug or carboy. The airlock cap should always stay on top when in use; it has several small holes in it that allow gas to escape but prevent the water inside from quickly spilling out if tipped or jostled.
Simple and delicious, im gonna do it again
My favorite air lock. These work great.
I think it’s the second one I ordered first one was maybe I mean to big . Several orders . Only use clean equipment. Get the right size, these could be after using the right size, I don’t know anymore.!
Works just as told
