Faszinierend, wie dieser Künstler Steine balanciert.

Michael Grab (http://www.gravityglue.com/) has mastered the art of stone balancing. He explains how he does it. “The most fundamental element of balancing in a physical sense is finding some kind of “tripod” for the rock to stand on. Every rock is covered in a variety of tiny to large indentations that can act as a tripod for the rock to stand upright, or in most orientations you can think of with other rocks. By paying close attention to the feeling of the rocks, you will start to feel even the smallest clicks as the notches of the rocks in contact are moving over one another.
