I filled a tube with the Euglena medium from tube 1 (capacity: 15ml) and filtered all of the cheese out with a sieve. I did this because I guess that it attracts the organisms too much, so that they will swim to the cheese instead of the light. | |||
To make the light colorful I cut out stripes of transparent paper and wrapped them around the tube. I chose the fundamental colors yellow, red and blue for the first attempt. To let no "normal" light on the bottom of the tube in, I also prepared a cover made of black nontransparent paper. | |||
To not move the tubes when I put off the paper, I put them in my Euglena Workstation to keep them safe. So I can easily remove the paper without mixing the concentrations accidentally. | To not move the tubes when I put off the paper, I put them in my Euglena Workstation to keep them safe.
