Rock on Top of Another Rock by artists Fischili and Weiss outside The Serpentine Gallery oscillated between stability and instability, construction and destruction. The children embraced this concept and worked with various materials to explore these themes. Balancing was a key part of the workshop as the children manufactured rocks and tested how these could balance. They also looked at different rock structures and drew these from observation noticing the natural differentiated colour schemes and patternation. Its amazing when we really 'look' at what's in front of us how much more we notice!
