Red cabbage colour magic — Rainbow Orchard · Fruits & Vegetables
Berry says red cabbage hides a secret: its purple colour changes when you add lemon juice or baking soda. Fruits & Vegetables · MyLeoNes.
Your task
Choose the best option at each step.
- Simply put, the anthocyanins in red cabbage change colour with sour and soapy-feeling things. Sour things like lemon juice or vinegar turn the purple water pink or red. Baking soda turns it blue, and more turns it green.
- Invented stories to learn from, not medical or diet advice. Every body and every family eats differently. For health or allergy questions, talk to a trusted adult or a health professional.
- Nothing about you or what you eat is collected.
Score
- Plant & food knowledge — You understood how this part of the plant world works.
- Caring for the planet — You chose what is kind to the garden and the planet.
- Safe & ask for help — You stayed safe and knew when to ask a trusted adult.
In real life
This is the same reason red cabbage cooked with a splash of vinegar or with sour apples stays a bright red-purple, while cabbage cooked in hard tap water can turn bluish.
