I heard of many people using balloons as airlocks and just letting the air out when they get full, but I actually did it and found that on the large bottle openings (around 4cm) they just naturally let the pressure out and never inflate, I can also squeeze the balloon and they hiss out the extra air inside.
So I am thinking... Do I really need proper brewing airlocks? To me I don't see any reason other than being able to time the bubbles, and I could also just time the farts with this if i want haha. This is easier, cheaper and thus I will never run out of airlocks. I do of course clean the inside of the balloon very well before using.
These are 2 ciders btw, am thinking to brew beer the same though.
