Jiffy Juice is a powder extracted from red cabbage. It can be used as an acid-base pH indicator for common household items. To use, mix a small amount of the powder with water. Pour some of this liquid into a container and then add a small amount of another item of your choice to test its pH. If your chosen item is acidic, the jiffy juice will turn a red color. If your chosen item is basic, the jiffy juice will turn a green color. Instructions for use will be included with product along with a pH scale to compare your results.
