The Science Behind the Reaction
Anthocyanins are chemicals that change color when introduced to certain conditions: purple for neutral conditions (pH 7.0), red for acidic conditions (pH < 7.0), and blue for basic conditions (pH>7.0).
1. Compare the acidity of the different drinks in your fridge.
2. Paint a whole sheet with the liquid and then sprinkle on baking soda and lemon juice for a creative work of art!
