Kitchen ingredients are simmered down to natural dye: beetroot for deep pink, turmeric for golden yellow, red cabbage for blue-green, spinach for pale sage. Once cooled, a piece of white cotton goes in and the colour transfers. The muted, organic result looks entirely unlike synthetic dye, which has its own specific quality that children notice without being told.
What you need
- beetroot or turmeric or red cabbage
- water
- small pot
- white cotton fabric or cotton string
How to do it
- 1Say: "We're going to boil this [ingredient] and make dye. Watch the colour come out."
- 2Simmer in two cups of water for 20 minutes. The colour deepens as it cooks.
- 3Cool completely. Strain out the solids. Submerge a piece of white cotton for 30 minutes.
- 4Remove, rinse gently, and air dry. Compare colours from different plants side by side.
Variations
- Korb-Tür: If they won't wait for cooling: start the next pot while they're waiting. Action keeps attention.
- Ausstieg: Pull the fabric out of the bath. Rinse, dry. The colour is the final proof.
💡 Parent tip
Turmeric is the most dramatic — the yellow is intense and permanent. It also stains skin and worktops temporarily. Use old fabric on a covered surface and treat the staining as a feature, not a problem.
What your child develops
- Chemistry — plant pigments transfer to fabric through a simple molecular bond
- History — natural dye was the only available option before synthetic dye was invented in 1856
- Colour as a material property — seeing where colour comes from makes colour less abstract
Safety notes
- Adult handles hot liquid. Turmeric stains skin and surfaces. Work on a protected surface.
