Working only with rocks, gravity, and patience, artist Michael Grab (previously) builds precarious towers and bridges that seem to defy gravity. Grab first tried stone balancing during the summer of 2008 while exploring Boulder Creek in Boulder, Colorado, and quickly discovered an innate ability to build increasingly complicated, free standing stacks of rocks. While his stone sculptures rely heavily on intuition and experience, there’s actually a method he uses in most of his work involving hidden “tripods” found on the surface of any rock. He shares in detail:

Balance requires a minimum of three contact points. Luckily, every rock is covered in a variety of tiny to large indentations that can act as a natural tripo for the rock to stand upright, or in most orientations you can think of with other rocks. By paying close attention to the vibrations of the rocks, you will start to feel even the smallest “clicks” as the notches of the rocks are moving over one another. In the finest “point-balances,” these clicks can be felt on a scale smaller than millimeters, and in rare cases can even go undetected, in which case intuition and experience become quite useful.

You can watch the video above to see Grab at work over the last year, and also see more photography of his stone balancing in his online portfolio or on Facebook. Grab survives mostly off print sales, so if you’re in need of a fancy new calendar for 2015, he’s got you covered.
