Atelier : Craies urbaines

What if the city walls became ephemeral spaces of expression? During this workshop, you will make your own chalks from a simple mixture of plaster, alum salt and pigments, before giving them shapes and colors.

By manipulating the materials, you will discover the basics of a chemical transformation and understand how a powder becomes solid. Once ready, these chalks make it possible to write, draw and share messages in public space… before the rain washes them away.

An activity with Les Inventeurs at the crossroads of science and freedom of expression, to experience the city differently.

A 4-hand workshop to share between you and the child you accompany. Anyone taking part in the workshop must book a place (children and accompanying adults).
