I took two pieces of glass (10x15cm) and glued them together on three of four sides. In my first try I used sealing glue but it came out that it was not watertight. So I tried again with silicone.

Between the two glass plates there is a small gap of about 2mm. In this gap I filled the Euglena medium from the Erlenmeyer flask. It is conspicuous that the medium does not seem to be green but very clear in this vessel, because the amount of medium is so small. The whole installation is covered with dark, nontranspartent paper on both sides. In the paper I cut some small shapes. I put the installation in front of a daylight lamp.

Because Euglena move to light sources the concentration should be remarkable higher in the areas where the vessel is not covered with dark paper.

'''Outcome'''
After two hours I removed the paper from the installation. Luckily the experiment was successful and there is actually a clear copy of the letters I cut in the paper.
Next time I am going to figure out which camera angle and backround I need to take a better photo. I also want to use a different motif.

Note: I will start this experiment as soon as the Euglena medium is greenish enough to recognize the visual difference.
