Ok so my room is pretty warm, so I am putting my fermenters in a tub of water, and adding ice as needed to cool em down. Just now I poured ice cold water over my better bottle, and my air-lock started bubbling... backwards. I assume the cold is affecting the plastic. but drawing air into the fermenter can't be good.... right?
