The result of an experiment with Physarum Polycephalum and electricity has shown that it is not only a good conductor, but does produce a very small voltage during its growth. The voltage again is oscillating in the pattern of the plasma flow of the organism. The produced voltage and its resulting oscillation needs to be amplified to be able to be used, then send to an Arduino, where the frequency is calculated. Eventually, the signal is send through Serial into Processing, where the frequency is converted to an auditive frequency that can be played on a speaker and a graph that is shown on a screen. At the end, with an exciter speaker, the audio is fed back to the slime mold, to stimulate it. Like a feedback loop, or a self stimulation it interacts with itself and immediately giving the signal back to the computer. | The result of an experiment with Physarum Polycephalum and electricity has shown that it is not only a good conductor, but does produce a very small voltage during its growth.

The installation is showing a laboratory setting, where a petri dish is prepared with agar medium and electrodes. The cables lead into a box or machine with a screen that is showing the graph, the aesthetics of the box can be compared to an oscilloscope. | The installation is showing a laboratory setting, where a petri dish is prepared with agar medium and electrodes.

After witnessing this process I started isolating them and put most of them in a cardboard box. Then the same happened. After that I tried to feed them with leaves that fell off one of my plants after moving to Weimar. First, it was curious to see what it was but immediately stepped back from it. After that I fed it again with oats, but unfortunately they all got contaminated and either formed spores or mold. | After witnessing this process I started isolating them and put most of them in a cardboard box.

Another experiment was to see how the physarum conducts electricity. There were two problems I have been facing. One was that the voltage it conducted was in a range of millivolts. Second, the agar medium was also a good conductor, so my measurements were not very precise at that stage. Therefore, I transferred the to the cardboard to do experiments, but eventually they all „died“. | Another experiment was to see how the physarum conducts electricity.
