A visit to the Museo Galileo concludes with the interactive area, consisting of three rooms devoted to the tangible and virtual exploration of some Galilean instruments. Here visitors can understand the experimental component of the research conducted by Galileo, an indispensable topic in a museum devoted to the great Tuscan scientist.

The first room compares ancient cosmological systems with the new celestial world discovered by Galileo. The laws of motion -from planetary motion to the fall of bodies- are illustrated as well. The second room shows the relationship between the search for longitude and the measurement of time. Ancient mechanical clocks are displayed in the third room. The whole interactive area offers visitors the chance to interact with working models and multimedia accessible on touch screens. Visitors can thus have "sensible experiences" and learn how scientific instruments work. That restores the specific purpose of objects designed to be used.
