Using Gravity as Glue

Michael Grab, whose work we have shared previously, is still working his magic with rocks. Stacking stones with the upmost precision and patience, he then destroys his precarious creations in ways that look amazing when played backwards, as shown towards the end of the video above. Grab shares with thisiscolossal:

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 tripod 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.

And here’s Robert Krulwich about two years ago:

The artist who did this, Michael Grab, is a balancer of rocks. In an interview on Compliment Vices, he describes what happens when he builds these sculptures in front of live audiences, which, apparently, he’s done a few times — in Costa Rica, in Italy. Once, at the Boulder Creek Path Festival in Boulder, Colo., a guy came up to him and said, “My brother absolutely does not believe these are balanced like this. He thinks there’s bars or glue.” He demanded proof that these sculptures were for real.

“Everybody’s watching, everybody heard the whole exchange,” Michael says. “So I just go up and tap one in the middle and it just collapses. And everyone is like [gasp!] So I just like, get down, start making it again. Make it a tiny bit different.”
