I am doing a project on flower pigmentation with a bunch of third graders and I have decided to add rubbing alcohol to produce the many colors on a paper towel. What color flower is the best to use so that more than one color appears? And how much rubbing alcohol should I use?

I haven't heard of this technique before. If you do this in the classroom, make sure there is plenty of ventilation, open windows, etc. I don't think the vapors are good to breathe in.
