The failure of the first experiment therefore becomes part of the project. It shows how an artistic idea can meet biological limits, and how the concept can evolve after understanding what actually happens. | The failure of the first experiment therefore becomes part of the project.

= Introduction = | |||
For the second stage of this project, I wanted to explore the interaction between two slime mold species under shared environmental conditions. Instead of focusing on coexistence, this experiment investigates how two organisms respond when they compete for the same resources. | |||
The two species used are '''Badhamia''' and '''Physarum polycephalum'''. Both are plasmodial slime molds that forage by expanding dynamic networks toward food sources. Because they rely on similar nutrients, placing them in the same Petri dish creates a situation in which their growth patterns and interactions can be directly observed. | |||
As in the first experiment, one food source was colored with red pigment to make the two organisms easier to distinguish during time-lapse recording. | |||
The experiment was documented using automated photography. The resulting image sequence will be processed into a time-lapse film, allowing the interaction between the two slime molds to be observed over time. | |||
Rather than asking whether the organisms can peacefully share a habitat, this experiment asks a different question: | |||
'''How do two slime molds behave when they compete for the same space and food?''' | |||
