So right now I have a test tube with my ants in it and I have my the mini-hearth I bought a few years ago. Thing is, when I bought my mini-hearth, I decided to choose the worst possible connection size(3/8''). I don't think there are any test tubes that small so I don't really know what I was thinking.
The test tube is standard(15ish mm) and I have two pieces of tubing, one that fits over the test tube and the other that is only a tiny bit bigger than the 3/8' connection and fits the test tubes inner diameter. Could I just hot glue the test tube to the mini-hearth? How do people normally do these things?
Right now they are in an outworld, but I want to move them so it's a more manageable setup.
