Does anyone have any tips?
I'd suggest using a thinner straw (it helps you distinguish between each percentage more easily). Also, if it cannot stand straight, it means that there's not enough clay, so add a tiny bit more until it begins to stand straight.
So does using a standard straw from a restaurant or something usually work well?
