(english, french, german). the explanations are simple and can be understood even by a young audience. many games and experiences are available for self-made throughout the visit. the animation around static electricity is well done and generally delights children. there is also the "nostalgia" part in which we can find the household appliances of our youth, that of our parents, or even our grandparents. the setting is warm, informative and entertaining. the museum is quite well done in all. it provides useful knowledge about electricity.
