The Science Museum of Barcelona is a must visit for kids as well as the people interested in science. The chief focus of the museum is on the interactive exhibits that are organized all year long.
In addition to the experimental exhibitions, the museum also has an indoor mangrove forest which is home to birds and fishes. The optical perceptions/illusion area is another highlight that never fails to impress the visitors.
The museums also features a planetarium where one can see demonstrations of half an hour duration.
