The European Researchers' Night 2024 in Brčko—a pan-European science festival illuminating the wonders of research through hands-on public events, was held in Mjesna zajednica Eš naselje and organized by local collaborators led by Mali princ NGO. This year it was held on September 27, 2024, from 17:00 to 21:00 amid the festival's lineup of experimental archaeology and creative explorations. With our workshop in this session we exemplify how education, recycling, and scientific inquiry can converge through inquisitive nudges toward sustainability, igniting a spark of wonder in the evening's communal quest for greener innovations.
