The work consists, on the one hand, of a room that contains an environment control system necessary to grow oyster mushrooms (Pleurotus ostreatus), one of the best known edible mushrooms in the world. The incubator would be located on the exterior patio of the MBVM, introducing a pool, which would be the source of humidity that the fungi need for their growth.

On the other hand, the pool will be intervened, installing plates of different diameters in it, generating a homogeneous waterfall, behind which the fungi will grow.

As the environmental conditions are specific and contamination must be avoided, the room cannot have a large flow of people, so it is proposed that it not be open to the public, instead, a security camera will be installed inside the incubator, projecting in closed circuit into the MBVM. In this way, the projection proposes the visualization of a new world, hidden in a closed humidification system, but visible by a closed circuit television.

The generation of environments conducive to the growth and development of mushroom crops appears as a concept that questions and reflects on the role of humans in their ecosystem and how we are designing our existence for the coming years. Ingold (2012) proposes in the design of environments for life, a mutual coexistence and co-development, which is precisely how fungi live; forming a rhizomatic structure, the association of the mycelium with the roots of the plants and the interconnection of all the actors of nature. The process of inhabiting fungi is based on this, on the interactions between the internal specificity of the genes of each species and the external environmental conditions, in order to give continuity to the biological cycle and produce an environment conducive to life.

Fountain is an installation that proposes the creation of a new controlled temperature environment, based on the circulation of water. Composed of a pyramid-shaped dome, structured by iron and biodegradable plastic, it contains a kind of water border inside. This damp curtain is presented as a transparent wrapper for a new world where oyster mushrooms proliferate. These coexist with each other on an octagonal wooden structure, hidden behind the waterfall that extends from the original pool of the museum. Behind the curtain of water, there is a new landscape with environmental conditions that depend on water, temperature, and oxygen.

The work can only be seen from the outside, being able to enter its interior from the projection of a closed TV system, by means of a security camera.

This approach is taken to avoid an unbalance of the controlled environment, produced because of temperature changes when continuously opening and closing the dome. At the same time, the non-opening of the incubator gives a sacred and untouchable meaning to the work, producing two parallel temporalities.
