-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.
+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.
