This sciences museum for children, related to the Exploratorium of California offers children to discover and learn about sciences, thanks to several manipulations, experiences, and installations. Strongly involved for education, arts, new technology, sciences, and human exchange, this museum is modern and attractive. Despite all these great elements, this museum has a real communication problem. Dematerialized and sanitized cultural communication isn't a solution for this kind of museum. As everything is organized in workshops, the new visual identity and the communication of the museum could be done by laboratory workshops where children could create posters and communication objects thanks to modular forms, printed transparent papers and other objects. Children would experiment and discover through arts and mutual exchange.
