What experiment can be used to obtain aqueuous solution of an indicator from berries?

To obtain an aqueous solution of an indicator from berries, you can perform a simple extraction experiment. Start by crushing the berries to release their juices, then mix the crushed berries with a small amount of water in a container. Heat the mixture gently to help extract the pigments, then strain the liquid through a fine mesh or cheesecloth to separate the solids. The resulting colored liquid can be used as a natural pH indicator, as many berries contain anthocyanins that change color with pH variations.
