How does Euglena react to colors? | |||
'''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.

Can I control Euglena's movement? | |||
'''Setup:''' I took two pieces of glass (10x15cm) and glued them together on three of four sides. In my first attempt I used sealing glue but it came out that it wasn't watertight. So I tried again with silicone. | |||
Between the two glass plates there is a small gap of about 2mm.This gap is filled with the Euglena medium and Euglena. The whole installation is covered with dark, nontranspartent paper on both sides. In the paper I cut some small shapes. | |||
