We did not have any child with us and we have already visited a few science museums with electricity sections (for instance in Milano, Italy and in Munich, Germany). Maybe due to these reasons, we have been disappointed. Indeed, compared to other museums, Electropolis has few ancient apparatuses; the much-advertised electricity show basically only shows to children that when "minuses" (i.e., electrons) are removed from materials, they want to come back and in so doing, they generate sparks. The spoken explanations (for instance at the entrance, with the model city and in the electricity show) are in French only. Almost no explanation is provided on how a nuclear power generator works; note that the France national grid relies heavily on nuclear power; maybe they are ashamed of it...From the show perspective, there is not even any big sparks generator, which is almost commonplace in similar museums. We'd save two parts only: the history of electricity, with a clear and interesting explanation of the role of the earliest scientists; and the impressive generator at the lower level of the museum.
