Universal Indicator Test!
Not sure if the cabbage is red, blue, or purple? No problem!
However, what we do know is that if Mrs. Green and Y5 were ever lost in the jungle and had a red cabbage, they would know how to make safe drinking water using the brilliant Red Cabbage Indicator test. The anthocyanin content in the cabbage is released when it is boiled in water, making it an excellent experiment to test acidity levels. Great job, Y5!
