The Conseil d'Architecture, d'Urbanisme et de l'Environnement invites school children to make seed bombs that they can then launch in their villages to flower them!

The principle is to make earthen and clay balls containing seeds that can be thrown in places more or less accessible: its garden, streets, undeveloped areas (urban wastelands, wastelands, etc.).
With any luck, the seeds will germinate after a few weeks or next spring!
