This is hilarious! I put my yeast starter with an airlock in my chest freezer to cool down from 85 deg F (yikes) and now it’s at 77ish. The change in temperature caused a negative pressure in my erlenmeyer Flask! The airlock is now sucking in Oxygen! I find this hilarious and I don’t know why. Probably because it’s basic Ideal Gas Law and I didn’t think about it (obviously ) but after about 1min on the stir plate it’s back to normal, pushing out CO2. I’m sure the Oxygen is nothing to worry about since the few oxygen bubbles will probably feed the yeast rather than produce off flavors.
Happy brewing! Cheers!
