Stone balancing

[native]

The stones will never fall if they aren't disturbed, because the center of gravity has to be found. It's actually better to balance one stone on another that is already stable instead of balancing a single stone on a flat surface. That way you can use the inclined surface of the support stone to balance out some of the top-heaviness..which creates the illusion that it looks impossible.

It's implied but it's not easy. I've spent 2 hours trying this and have only been successful twice. Since winter has settled in I haven't been able to practice.
