During the activities of the “Zientzia Astea” (Science Week) in Donostia, I got the opportunity to participate in the “Zientzia Club”. In this event 9 speakers, including myself, delivered a 10 min talk about a scientific topic for an open audience. I decided to talk about soft matter, making emphasis in my lactose intolerance problems ! It was a really fun night, and I enjoyed all presentations very very much! Looking forward to repeat next year 🙂 !
