A pH indicator can be made out of Grape Juice or beetroot or even eggplant. Grate 1/4 cup of beetroot or eggplant into 2 cup water, boil for 10 min and strain for the dark liquid, by the way grape juice could be used right out of carton. Add indicator to the substance that is being tested, it will be more red for pH of 2 and greener for pH of 12, and test for better knowledge of all colors that pH indicator can turn.

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.
