Effervescience 2026 — En quête de science

For its 31st edition, Effervescience takes place at several venues in Le Mans from September 30 to October 30 around the theme “En quête de science” (In Search of Science). Carried collectively for thirty years by local Le Mans organizations, the project invites people to question, experiment with, and understand the scientific method, in order to feed knowledge and critical thinking. The activities are aimed at school groups and the general public alike. The details of events and venues are published by the organizers throughout the month.
