Third day of the workshop started with soap experiments. Materials needed for these were liquid soap, a plastic bowl and piano strings. Each group filled their bowl with some liquid soap and started to investigate the material capabilities of the soap by trying to manipulate it through wires. By bending the piano strips, students were obtaining knots, which would be covered with liquid soap, in such a way to form “minimal surface” topologies, controlled by the shape of the strings.
Following this analogous phase, students started to apply the same principal on Grasshopper. With the usage of scripting, soap experiments with minimal surface topologies got digitalized. By manipulating the curves and their control points, students were able to change the topology of the surfaces, which was in the end, a back and forth process.
