-'''Experiment 1:''' 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.
-'''Experiment 2:''' Researchers found that if they put a frog in a pan of boiling water, the frog can quickly jump out. On the other hand, if they put a frog in cold water and put the water to boil over time, the frog will be boiled to death.

-In the experiment, the same concentration of coffee will provide caffeine to the medium. Physarums will be split into three Samples. The first one will grow in a normal 2% agar medium at the beginning. And then move into the coffee medium directly. In the second sample, the amount of coffee in the medium will be very small at first. Then after each time the Physrum has adapted to the new environment, increase the amount of coffee gradually until the concentration of coffee is the same as the default value.
-The third sample lets the Physarum who can grow on the default coffee medium and another one who hasn't lived on the coffee medium before, live together for a period of time. After that, move them to the default coffee medium too. Observe and record the difference in the growth of Physarums among the three samples. Find out whether they can adapt to the coffee environment.
