To keep the slime mold from escaping it has to be fed regularly. How often and in what way it has to be fed depends on the purpose of the culture. It is possible to do this under the flow hood in an attempt to keep things sterile, however it is also possible to do it on the usual work space (disinfect first and still keep hands and tweezers clean) | To keep the slime mold from escaping it has to be fed regularly.

'''<u><big>Projects with Physarum Policephalum</big></u>''' | |||
'''<big>Improving Tokyo's rail system (by Atsushi Tero from Hokkaido University, Sapporo, Japan)</big>''' | |||
While looking for food to continue growing the slime mold detects the food from afar and expands various brands in it's direction. When it has reached the food sources it only keeps the branches with the most efficient way of transporting the nutrients. | |||
Japanese scientists from the Hokkaido University in Sapporo used this characteristic to try and find room for improvement in Tokyo's rail system. | |||
They placed oat flakes in a wet dish resembling the locations of different major cities in the Tokyo area. Since the slime mold prefers dark places, it was possible for Tero to use bright light as mountains and lakes so that the slime mold would avoid these spots while growing towards the oat flakes. | |||
In the end the slime mold created a network which was very similar to the actual rail system. | |||

'''<big>"Fusion" - Creating Art(ist) with slime mold (Project by Hanna Bremerich, Bauhaus Universität Weimar)</big>''' | |||
With this project I planned on permanently fusing the artwork and the artist together so that they are completely inseparable. Usually the answer to the question of how much of a connection there is between an artist and their work isn't a trivial one. There is no doubt that because of the intention and the process of creating the artwork there is always "a part" of the artist themselves integrated in the painting but mostly it's not always a physical connection and that is exactly what I wanted to achieve: An artwork that is the artist themselves at the same time. | |||

* To start the project I studied the movement of the slime mold during our course "Growing microorganisms for bioart projects" so that I could create a drawing which the slime mold theoretically could create in a similar way. | |||

* I prepared plastic dishes with an agar-agar-medium in the dimensions of a A4-sheet | |||
* I placed the oat flakes with Physarum on them in the spots of bigger "blobs" and the food on the spots with that represented the individual flakes | |||
* I checked on the slime mold every day and kept placing new oat flakes onto the same spots every day so that the slime mold would hopefully not move away from the spots resembled in the drawing and would create something similar | |||
* After 14 days I ended the project | |||
* The slime mold created multiple versions that were similar to the drawing, however day 11-14 were the closest | |||
