I thought I was done with asking dumb questions in regard to brewing, but what are those strips I see on the outside of carboys in some of the posters pictures?
It's a black strip that appears to have numbers on it, or a scale of somekind. I assume it is for clarrity or timelapse or something, but just curious to what the hell it is, what it does, and how I get one if they are usefull. Thanks.
