Erika Szőke experimented with the possibilities of electricity, using the natural resources of Vojka. The raw material she used to produce power was a mixture of local soil, water and salt. She managed to run a projector with the electric current, bringing to life images of plants that are no longer present in the region of Slovakia (since 2015) according to a red-list of extinct plants. The idea was then developed further using her own photographic technique and local soil as a pigment. Erika thus managed to revitalize the red-listed extinct flora.
