First of all I cooked a medium for Euglena which should promote the reproduction. It contains specific nutrients. Combined with a light position, e.g. at the window or in front of a lamp, they should accrete fast. | First of all I cooked a medium for Euglena which should promote the reproduction.

Those microorganisms cannot be seen with the naked eye but if the population increases, the medium becomes greenish. This is my target goal because that makes it easier to work with. | Those microorganisms cannot be seen with the naked eye but if the population increases, the medium becomes greenish.

'''Setup:''' I filled a tube with the Euglena medium (capacity: 15ml) and added about ten drops of Euglenas. To make the light colorful I cut out three stripes of transparent paper and wrapped them around the tube. I chose the fundamental colors yellow, red and blue. | '''Setup:''' I filled a tube with the Euglena medium (capacity: 15ml) and added about ten drops of Euglenas.
