Direct or Gradual ?
The environment plays a very important role in the growth of organisms. In addition to different environments, even the way the environment changes have an impact on them. Facing this, organisms always show different feedbacks.
My idea
Add a substance that Physarum doesn't like into their living environment in different ways. What will happen to the growth of Physarum? If this unusual living environment is not faced by this Physarum itself but through communication with other Physarum, what will the result be when this unexperienced Physarum moving into the unusual environment?
Inspiration
Between Physarum and the food, scientists built a bridge containing some salt which Physarum doesn't like. But in order to get food, the slime crossed the salt bridge. After that, the scientist put the slime into hibernation. After resuscitation, it can still cross over the salt bridge, and the speed is faster than the last time. So scientists think they have learning and memory functions.
Techinical solution
In the experiment, the slimes are split into two parts. One is fed with a normal 2% agar medium. In the other one's medium, the water with an appropriate amount of coffee will be replaced. In the beginning, the amount of coffee is small, allowing slimes to grow on it. After that, the amount of coffee will be increased after every time the slime adapts to the environment of the medium. Then let the slime that can grow on the coffee medium and the slime that have not lived on the coffee medium live together on the ordinary agar medium for a period of time. Finally, the slimes who have lived together for a period of time are raised in a coffee medium to observe whether they can accept the coffee environment.
The way I took Time-lapse videos:
Process
When raising the Physarum Polycephalum, many different cultivation environments have been tried. The coffin is one of the things they don't like coffee. What if coffee is added to their growth medium, will they adapt to such an environment?

Results
Sample1:Cultivate directly in coffee-medium.
Sample2:Gradually grow in coffee-medium.
Sample3:Let Sample1 and Sample2 grow together, then grow in coffee-medium.
