In the second lecture of our 'Diy biolab drivers license' course, students saw live how slime mold transfers nutrients within its body. Firstly the flow goes in one direction, after a while stops and then moves in another direction. Since this is how a slime mold grows and distributes nutrients to every part of its body, I wondered: what if the slime mold were to consume multicolored food—would it change its color as a result? And what if there were several different colors involved? Would distinct color boundaries be visible, or would there be soft transitions? Or would the slime mold simply turn a single, uniform color? | In the second lecture of our 'Diy biolab drivers license' course, students saw live how slime mold transfers nutrients within its body.

</gallery>When Petri dished were ready, it was the time to prepare camera set-up for timelapse filming. After reading some manuals and instructions I was able to set settings, that camera makes one photo each minute. For the first experiment I decided to make 48 frames (48 minutes of filming), which in the end will be 2 seconds video. My teacher also suggested to feed mother culture to make it stronger for the future.<gallery> | |||
