Glass is made of Silica (SiO2). In this interactive installation, the visitor can interact with a glass object generating a visual acoustic representation of the Silica components by touch. This representation is based on the colour of light emitted by the Silica atoms in the nanoscale, which is red and violet. The sound corresponds to a mathematical equation that relates the wavelength of the light (nm) with the frequency of the sound (Hz). So, the visitor can travel to the world of atomic nanoscale and discover new behaviours of matter. What colour does matter have in the nanoscale, and how does that colour sound like?
