Try repeating the experiment backwards, i.e. start with the "acid" to make a pink or red solution, then slowly add "base" to change the color back to purple, then green or blue. Try different combinations of acids and bases. For one last experiment, use your cup with baking or washing soda added to the cabbage juice (it should be bluish colored).
experiment we will use an indicator, 2,6-dichloroindophenol (In–OH), to see how protonation and deprotonation can be used to encourage a compound to move between organic and aqueous layers. 2,6-Dichloroindophenol (In–OH) itself is red, but its conjugate base (In–O–) is blue. The color will tell you if it's protonated or deprotonated.
Color Changing Milk Experiment to Magically Mix Colors I’ve tried doing this magic color changing milk experiment in the past, but remember not having the best great success with it. I don’t remember what we did differently though because this time it worked great.
Purpose. To explore what happens to the amount of different substances as they change from a solid to a liquid or a liquid to solid. Context. This lesson is the third in a three-part series that addresses a concept that is central to the understanding of the water cycle—that water is able to take many forms but is still water.
Therefore, the solutions can have many different shades of color. You can expand on the experiment by making the solutions in the cups more saturated (adding more reagent) or increasing/decreasing the water temperature and observing how the color of the liquid changes. Also, try using clear, bottled, non-carbonated water.

Start by melting paraffin (from candle stubs or from blocks of canning wax from the grocery store) in a double boiler. Do not melt over an open flame or it may ignite. Stir in one or two tablespoons of the recommended dry chemical. Let it cool, but while it is still liquid, pour the wax into small paper cake cups.
