Reddit reviews Center of Gravity: A Guide to the Practice of Rock Balancing

It's not sand, it's physics. OP is my dad. Here's his book on how it's done: https://www.amazon.com/Center-Gravity-Guide-Practice-Balancing/dp/1482026341

For each contact point the center of gravity of the rock(s) above must be directly above the contact, which is usually a little chip, depression, or flat spot where the rocks can "nestle." Takes some practice, but if you start with one rock on another, you can soon develop a feel for it. I wrote a book on rock balancing. It's on Amazon: http://www.amazon.com/dp/1482026341

/u/mary_gen hadn't replied to you yet, so I thought I'd let you know - OP is the author of this book: https://www.amazon.com/Center-Gravity-Guide-Practice-Balancing/dp/1482026341

Idk man the author of this book and their username check out. Upon further investigation it looks like they posted the images several years ago from the same account. May I ask what proof you found? Not saying you're lying, just want to confirm.
