you shop it/ put it in a bowl and MASH it up, then add boiling water to help denature the cells and then you use a tray with dips in it and you add small samples of your filtered solution onto the tray, then you add drips of acids/ alkalies and you will notice a change of colour!
Simple!!

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.

What food cures sickness?
From my personal research, jarred silver skin onions in WHITE vinegar! I never turn to medicines, i only turn to onions to cure my sickness! I believe this cures the sickness by... The onions trapping the vinegar in between the layers. Once digested the onions release the vinegar into the stomach. The vinegar then mixes with the stomach acids causing the acids to stop churning, to keep the stomach acids at bay.
