Olatu Talka is a cultural festival organized by the citizens of San Sebastián. During a weekend, the streets, squares and parks of the city become the scene of multiple activities in which citizens are protagonists of cultural action. The Urban Science section aims bringing science closer to the citizens and, at the same time, making visible the work that is done in the research centers of the city. Monologues, talks, workshops and laboratories for small, small and major exhibitions and other activities are carried out throughout the day.

Several PhD students and postdocs from CIC biomaGUNE participated at the Olatu Talka Urban Zientzia (Urban Science) 2016 and 2017 editions by organizing a photo exhibition of food at the micro scale “Food & Science” and an experimental workshop entitled “GuessFood”.
