I'm doing an experiment on which flower would produce the best scented essential oil but I want the process to be easy to prove that you can make your own essential oils instead of buying them at a higher price. So, I don't want to use a still or something like that because not everyone has stils at home. I need a simple, long lasting process that everyone can understand. On the internet, the processes I found were cumbersome (ex: steam distillation) composing of heavy equipment. Can anyone give me an easier process?

I was thinking of setting up the usual apparatus with elodea and in the beaker of water used for heat absorption, I would place different coloured food colourings at different times. However, my teacher suggested we use bromothymol blue and its colour change with carbondioxide in some way
