Researchers´Night in 2024 was accompanied by the theme of Transformations, which was projected on the HIPC building and included in alchemical theatre, practical demonstrations such as the transformation of smells and molecular gastronomy, lectures and visits to the laboratories themselves. HIPC hosted this event as a part of the Europe-wide event with its approach to the diversity of science and its impact on daily lives in easy understanding and inspiring ways. The European Researchers' Night aims to bring research and researchers closer to the public, promote excellent research projects across Europe and beyond, increase the interest of young people in science and research careers and showcase the impact of researchers' work on people's daily lives. As part of these excursions, visitors were also introduced to the Big and Little Brother attachments, which allow the preparation of tiny catalysts - clusters. The transformation of aggregates in the molecular kitchen was dealt with by our ESR - Early-Stage Researchers - Stanislav Valtera and Karolína Simkovičová, these demonstrations were a great success with all the visitors.
