The Parc des Délices in Grand-Saconnex transforms into an open-air cinema with CineGlobe, the science film festival orbiting around CERN. From 4:00 pm, children and adults alike can take part in two fun, science-themed workshops – building a camera from a Tetra Pak or creating a zoetrope – before settling into a deckchair for the free 8:30 pm screening of the animated film Lightyear (French version). A snack bar will be available, with a friendly atmosphere guaranteed, and the event will move to the Salle des Délices in case of rain.
