Defying gravity: The art of rock balancing
MANILA. Philippines -- Out of the numerous fundamental forces of nature, gravity is one natural phenomenon that acts as an invisible grip governing our planet.
While rock sculptures would seem to defy gravity, it is the same force that holds them together.
Rock balancing is a performance art in which stones are piled into sculptures without any adhesives, making them look physically impossible. -- Green Living, ANC, March 27, 2013
