Animal mysteries: guess who I am?
by Alice Brighi
18:00-20:00, Salle de Médiation, with bleachers (-1).
This entertaining activity immerses the public in the captivating world of nocturnal animals. Audiences use their imagination and listening skills to guess an animal described solely by means of its ID card. Following the description, the audience identifies the animal among those displayed in front of them, and additional information is provided on their nocturnal lifestyle. As a souvenir, children leave with a bat mask.
