Ready to impress your friends? Boil a red cabbage and use the deep purple water as a pH indicator. This is pure magic. Add some lemon juice, and the purple turns pink. Add baking soda, and it turns blue-green. You can test your tap water, soda, or even rain—each one reacts differently.
It’s a visual feast. You’ll literally see how acidic or basic your water is based on the shade of purple. Plus, you’ll look like a kitchen wizard. Who knew chemistry could smell like coleslaw?
