Plastic_ity is a biotechnological sound installation composed of earthworms terrarium, layers of speakers with microplastics and soil profile in the bottom cylinder. The installation is constructed as an interface for earthworms to move microplastics to the deeper layers of soil with sound.

The terrarium inhabited by earthworms is located at the top of the installation and is equipped with probes that monitor the movement of earthworms. The movement in the terrarium controls the volume of prerecorded sound of earthworms.

The sound intensity influences transportation of the microplastics to the deeper layers of the installation. The prerecorded sounds thus become a 3-chanelled sound composition performed by earthworms while they move inside the terrarium.
