You can take the pH Indicator and start testing on various kind of liquids such as lemon juice, sour milk, milk, or even vinegar. To carry on the test, take the paint brush and dip in the liquid of your choice. Now with that brush dip paint on the pH indicator. The color on the pH indicator would change depending on whether the given liquid is an alkaline or acidic.
You can be innovative with various solutions instead of beet root for making pH indicator. Some other liquids include grape juice or even turmeric solution.
The pigment present in the beetroot, known as Anthocyanin acts as the pH indicator and changes it's color according to the presence of alkaline or acidic nature of the liquids tested.
