Hi
I've had a search but can't find the answer to my current puzzlement!
I'm about to use a hydrometer for the first time but don't have a test tube. Can I use an ordinary drinking glass or a glass jar or does it have to be something tall and thin?
(Yet another of the questions I never knew I'd have to ask.)
