Dye preparation As I don't posses a magnetic stirrer I had to improvise my own solution. My current protocol is as follows: Cut in excess leaves of some vegetable (usually a radish or a carrot, it doesn't matter much) Put leaves in a beaker Pour wanted amount of a solvent, making sure to not exceed 20% of the beaker's volume Put on a bass speaker and induce a standing wave in a fluid with high mode number. It's simple to do, I just set generator to 10hz and dial around until I find resonance peak. photo of chlorophyll extraction Solvents  In order to solve some mysteries, I decided to investigate an influence of the solvent on a dye a bit.  I made solutions of dye dissolved in 95% ethanol, 70% ethanol, 99.9% IPA and acetone. Thanks to the Christmas and New Years break, I did it at home and lacked the proper test equipment so the results aren't conclusive. All water-free solvents seemed to behave exactly the same.
