In order to make this kind of an indicator, you need: RED CABBAGE, A MIXER, WATER, STRAINER, ACID, BASE, BEAKER (or a glass).

Now, take a few of the red cabbage leaves and put them in the mixer, after that, put water into the mixer. Now: MIX! When you mix, strain off the cabbage-leaf parts into a beaker and you're ready to go. If you pour hydrochloric acid, the juice turns red, if you put ammonia, it turns green, if you put a solution of sodium hydroxide, it turns yellow. Of course, these are all lab-grade chemicals. You can also use (Lemon) Citric Acid, Acetic Acid(Vinegar), Sodium Bicarbonate(Baking Soda)...Hope I helped..! :)

Why is red cabbage indicator not a good experiment to measure buffering capacity?

A buffer absorbs or releases excess hydrogen ions, making the solution hold at a steady pH. Since red cabbage indicator makes a good pH indicator, it has a neutral pH. any amount of acids or bases added would change the pH of the red cabbage juices. If it made a good buffer, it would not make a good pH indicator.
