Cabbage Inks
Introduction
For thousands of years, people have used colors collected from nature to create art. Many plants have natural pigments, and the one in red cabbage (anthocyanin) is very special — it can change color when it’s mixed with ingredients from your kitchen. In this activity you will use acids (like lemon juice) and bases (like baking soda) to make your own rainbow of colorful paints from red cabbage!
