Example of the capillary experience

Basic principle :

- Two materials: a paper and a cotton yarn, both are immersed in coloured water

Will they let themselves be immersed and in how many time?

Metaphor of the impregnation during this residence of all the actors: residents, professionals, families?

First results: the cotton yarn seems waterproof for the moment (something I never imagined at all) while you can see the words harvested in the morning are quickly "infused".
