The next experiment was really neat. I had read on Poppytalk (which I found through Pineterest) that using vinegar or salt with red cabbage gave different colors. (She does a neat table runner with natural dyed fabrics--I definitely want to try this at some point!) I wanted to try this. This is actually why I didn't pre-soak. I wasn't sure what to do with the salt at the time. Now I have found recipes on how to do it (on Pioneer Thinking). And the neat thing is I was telling a family I tutor for about the experiment and the student I work with said, "Oh, I know why. We just learned this in chemistry class." She was so excited to see a real life application of it. It has to do with the pH of red cabbage. For more information to use as a lesson or possible understand yourself check out this explanation on About.com (plus it is really a neat science experiment there).
