Laboratoire Experimental' portrays the first collaboration between two artists, María Roldán (Colombian) and Annabelle Moreau (French), exploring the relationship between presence and absence, the passing and the permanent and the mutation between the states of dispersion of matter, inviting readers to reflect on the nature of the objects and their relationship. This book invites readers to search for new discoveries, resolving transformations and ephemeral states. 00Exhibition: Museu Nacional de História Natural e da Ciência, Lisbon, Portugal (25.05.-10.07.2016).
