During our workshop "A taste of research", participants explore the world of model organisms in research. They also conduct a behavioural assay on fruit fly (Drosophila melanogaster). More precisely, they test the colour vision of the flies by exposing them to different colours and checking whether the flies move towards the lights (positive phototaxis).

We designed this little test chamber to easily hold two vials taped together in place. The participants can the place the light source on one end of the test chamber and observe whether the flies move towards the light source or not.
As a light source, we use these macro photography lights from Adapatlux Studio https://adaptalux.com/shop/
We also designed a stackable rack to hold the lights. You can also add small magnets (diameter 6 mm, height 1 mm) to ensure that the parts really stay together during transport.
