Chemistry is just stuff bumping into other stuff and changing. Drag things off the shelf into the beaker and see what happens, then try the real thing at home.

Drag anything off the shelf into the beaker and watch what happens. Some things only react when they meet the right partner.

🥬Red Cabbage Colour DetectiveTurn a cabbage into a colour-changing acid detector. · 15 minHow to ▾Close ▴
You need
A few red cabbage leaves
Warm water from a grown-up
3 clear glasses
Lemon juice, plain water, baking soda
What to do
Soak chopped red cabbage in warm water until it turns deep purple, then strain it.
Pour the purple juice into three glasses.
Add lemon juice to the first, plain water to the second, baking soda to the third.
Watch each glass pick a different colour!
Why it happens: Red cabbage has a pigment called anthocyanin. It changes shape — and therefore colour — depending on how many hydrogen ions are floating around. Lots of them means acid (pink), very few means base (green).
