“Science4All. The Science Festival in Padua” is a great scientific communication project organized by the University dedicated to citizens of all ages to focus on the central role of scientific knowledge in the life of the community. Along the streets of the city, researchers from the University of Padua met the public to experiment with science in an engaging and fun way with laboratories, scientific experiments, games, scientific cafés, quizzes, guided tours, animated readings, shows, escape rooms, meetings, and screenings.
