This demonstration illustrates the presence and importance of chemistry in everyday objects, including our food. It is an interesting way to start the discussion of acids and bases or to connect acids and bases to the pH scale and extend the discussion to acid-base indicators. Red cabbage is an example of a naturally-occurring acid-base indicator. Many household products are acids or bases and often products that are used for similar tasks have similar pH values.
