You can use brightly coloured berries, flower petals and vegetables to make a natural indicator. The first thing you need to do is crush all your plant pieces using a pestle and mortar. Then you must add a little bit of methylated spirit. After that, keep on crushing until all the colour has come out. Then seperate the liquid from the plant remains using a pipette. Now you have a natural indicator. Hope this helped!
