The chemistry of color-changing tea


Today’s Video of the Day from the American Chemical Society describes the science behind color-changing butterfly pea flower tea.

Blue petals from the flowers of the butterfly-pea plant have been used in herbal beverages in Southeast Asia for centuries.

The blue flower tea contains chemically-reactive molecules that can change their structure depending on the acidity of the solution you put them in. When they change structure, they change color.
