Epoxy scale demo

Using a 2:1 epoxy scale. In the middle I say the distance is 44 to 1; I mean 44 to 100, of course.
The nice thing about this longer than usual design is that it reacts more slowly to adding weight, which makes it more accurate, and since the cup is not in a fixed spot on the left side you can mix up exactly as much as you need, rather than some fixed increment.
