A few months ago, I got interested in using waterless airlocks to avoid the hassle of dealing with an extra liquid outside the carboy.
I thought about buying some, but didn't want to pay $8 shipping for $3 items. So, I decided to make them myself. I've just written the whole thing up with pictures and all.
