A strange transformation has taken place at the Water Interpretation Center. This Halloween, the C.I.EAU invites visitors to put on their lab coats and take part in Mission Incognito, a scientific investigation designed especially for the occasion.
During this immersive activity, participants will need to observe their surroundings, find clues, and use their powers of deduction to figure out what happened. Their ultimate goal: to develop the cure that will reverse this mysterious transformation.
Become a scientist for the duration of a mission

Mission Incognito offers a unique and fun way to explore science. For about 45 minutes, participants will be immersed in an investigation that involves observation, critical thinking, and experimentation.
Young and old alike will have to work together to follow the clues, understand the phenomena they observe, and make progress until the mission is completed.
A Different Kind of Halloween Activity
With “Mission Incognito,” the C.I.EAU aims to offer an activity that combines the spirit of Halloween with scientific discovery.
The activity features Incognito, a character from the play *Eldorad’eau*, who takes part in this special Halloween science mission at the C.I.EAU.
Rather than simply observing, participants become active participants in the experience. Each clue brings them a little closer to the solution and allows them to explore science in a hands-on, interactive, and fun way.
