The Museum of Physics Instruments is located in the historic center of Pisa and is part of the University Museum System of the University of Pisa. The Museum has a very extensive collection that includes scientific instruments of physics and astronomy from the eighteenth century to the mid-twentieth century. The collection consists of an important archive that collects documents of the Physicist Pacinotti. The Museum is currently closed for restoration, but the educational activities take place inside the Scientific Playroom. The Playroom is responsible for reproducing the experiments that have made the history of science and scientists all over the world. The space takes its name from the Latin and indicates recreational activity, the game. The most important challenge of the Museum and the Playroom is therefore to teach and learn by playing, making adult and younger visitors passionate about scientific study.
