“The interactive light show is amazing!” we brought four children aged five to twelve, and everyone was happy to blow up. The favorite is the interactive light exhibition, a performance art composed of large screens and projectors, which users can "control" each exhibition through action. There is also an interesting display of electricity, and audiences can also participate in it. Although the language is only French, it soon floods with people explaining how protons, neutrons, electrons and how they interact with each other under different electric fields and stimulation.
