Cabbage Project Shirt Changes Color with the Climate

The innovative Cabbage Project shirt changes color to illustrate the effects of climate change.  Cabbage Project t-shirt is made of a cotton/hemp blend fabric that has been dyed with red cabbage juice. The juice is a natural pH indicator, and is purple when sent to the wearer, indicating a perfectly balanced pH level of 7. As the shirt is exposed to water, its color will change based on the water’s pH level, offering a visual reminder of the effects of climate change on water pollution.

    So to make the color change – we need to put different types of water on it ?
