What you need:

7 glasses 
7 teaspoons 
Soda 
Vinegar 
Baking Soda 
Water 
Sparkling water 
Laundry detergent (powder) 
Lemon juice 
Red cabbage 


How the experiment works: 

1. Together with your parents, cut the red cabbage into small, chunky pieces.  
2. Pour some water into a pot and boil the red cabbage for about 20 minutes.
3. Strain the contents of the pot through a sieve and pour the red cabbage juice into a container (bowl/glass/jar). 
4. Allow the red cabbage to cool - now, the experiment can begin! 
5. Add water to each glass, so that each glass is half full, then add a different "ingredient" into every glass (approx. one teaspoon - attention: use a clean teaspoon for each glass or rinse it in between). 
6. Stir the contents (Attention: use again a clean teaspoon for each glass or rinse the teaspoon in between). 
7. Now, pour into each glass a little of the red cabbage juice.

what is happening? 


What happened: 

Red cabbage juice is, in this experiment, used to indicate whether a solution is acidic or basic. The color spectrum of red cabbage ranges from light pink (=very acidic), to pink, purple (neutral), blue, turquoise, green and yellow (=very basic). The red cabbage is enchanted because you can see all the different colors and their respective pH levels.
