To make an indicator from onions, chop red onions and boil them in water for about 30 minutes to extract the pigment. Once cooled, strain the liquid to obtain a purple onion juice, which can act as a pH indicator. This juice changes color in response to different pH levels: it turns red in acidic solutions, purple in neutral solutions, and greenish-yellow in basic solutions. Store the indicator in a sealed container for future use.
