Apparently I'm having a hard time with this, one more try: *polycephalum
Hi Miles, I did a public experiment inviting visitors to an arts festival to feed the slime mould with whatever they fancied, in order to establish wider likes and dislikes http://slimoco.ning.com/video/physarum-experiment-no-016-likes-disl... (I thought it should broaden its culinary experiences beyond only oat flakes). Repellents included bicarbonate of soda, ibuprofen, chilli powder. Andrew Adamatsky has conducted a number of chemical substance experiments, detailed in his Physarum Machines book and in journal papers.
Bear in mind my experiment was not for scientific purposes but a means of engaging public audiences with biological behaviours. It is messy and without a control. Or any control for that matter… But it might offer you some other substances to test in a more rigorous manner.
And be great to share your results here, I'm sure many people are interested.
