"Well, we are working on a long term solution ( we are art-students, so color is important) - but I might take this to a new question/ thread cause it has nothing to do with the original question. "

"It will ditch the colour fast so you have to keep feeding it - sole food source basically. I found it doesn't like blue food colouring very much either. I had to use pure lab grade dye - I don't think the detergent would do it any…"

"Really? we tried a lot of different food colorings so far and easter egg color BUT after a day physarum got rid of the color.  Did you use the optical brightener from the washing powder or did you use a special one from lab equipment? "

Why does Physarum like chocolate?

Hi There, I was wondering if anyone could offer an explanation as to why a strong positive chemotactic response towards chocolate may be observed. I recently did an experiment to test various food sources and chocolate was favoured quite highly by my Physarum but I'm struggling to find any evidence as to why this might be for the discussion in my uni report? Any help or suggestions would be most appreciated. A friend suggested it could be potassium present in the chocolate. I don't know the…See More
