For the weekend i brought my three samples to my parents house in another city. To transport the Physarum safely in a train I repurposed the tool kit suitcase. It seems like the transportation and change of surrounding has not harmed the organisms. On the contrary, the Physarum is growing faster in the dark suitcase than in a shadowy place in my room.

The Physarum covers all of the petri-dish now. It is very bright and yellow.

The Physarum is back in Weimar and this morning it grew out of the petri-dish. Time for a new environment. I prepared a cardbox with baking paper, cooked a lot of agar medium and filled the cardbox with that. I used agar from the supermarket and a cardbox is not a totally serile environment. Will the Physarum still grow? I would love to imitate a small part of a forest, maybe inside of an aquarium where the Physarum can grow in an environment that is as natural as possible.

The Physarum is growing very fast in the improvised cardboard box environment. Even faster than in the petri dishes.
