====Procedure====  
  - Tear red cabbage leaves into small pieces and place them in a sealable plastic bag.  
  - Add about one cup of water, press out the air, and seal the bag.  
  - Squish the cabbage pieces in the water until the liquid turns dark blue.  
  - Pour the liquid into a cup and discard the cabbage pieces. This is your indicator solution.  
  - Place about one tablespoon of the indicator into a small cup.  
  - Add a few drops of the substance you want to test using a straw or dropper.  
  - Observe the color change and record your results.  
  - Use a fresh cup and new indicator liquid for each test.

/*******************************************************************************************************/

====Variations====
  * Try testing different types of fruit juices to compare their acidity.  
  * Test a range of cleaning products (excluding bleach) to see which are basic.   
  * Use the indicator on paper (soak paper strips in indicator, dry them, then use as test strips).
  * Use other natural indicators such as blueberry juice.

/*******************************************************************************************************/

====Safety Precautions====
  * Wear safety glasses or goggles when handling liquids.  
  * Do not eat or drink any of the substances tested.  
  * Work with an adult, especially when handling cleaning products.  
  * Wash hands before and after the activity.  
  * Tie back long hair and avoid loose clothing near liquids.  
  * Dispose of solid waste in the trash and pour liquids down the drain with plenty of water.

/*******************************************************************************************************/

====Questions to Consider====
  * Why does the cabbage indicator turn red or pink in acids but green or yellow in bases?  
  * Which household items were more acidic than you expected? More basic?  
  * Why is water considered neutral?  
  * How does this demonstration relate to the pH scale used in chemistry?  
  * Could other plants with natural pigments be used as acid-base indicators?
