A fun way to use anthocyanins is to extract them from red cabbage using a
blender, then add a variety of household items like ammonia, soap,
vinegar, etc to see color changes. One could make a parallel set using
buffers to set the pH for a series of colors and make color comparisons.
Some caution is needed because some of the substances add color that
interferes. The students are quite impressed with the array of colors
they can get.
