This exhibition offers a journey through the twenty years of the Experimenta Fair and its related activities, recreating and sharing an experience where science and emotion are intertwined. Images and videos convey the spirit that this initiative has maintained since its inception in 2005: to encourage a sense of wonder, fascination, and observation of natural phenomena and the technology that surrounds us, as well as to foster an understanding of science—a comprehension accessible to everyone. Beyond their physical form, the projects displayed here bear witness to learning, successes, and failures, just as they do at the Fair itself. They also serve as tools for transmitting scientific culture to the public through a highly participatory and festive activity based on interest and curiosity.
