Holi Natural Colours Science Experiment — Make Your Own Holi Powder
Discover how traditional Holi colours were made from flowers, spices, and leaves. Extract real colour from turmeric, beetroot, and marigold petals — a Holi science experiment that connects chemistry to culture.
What you need
- ✓Turmeric powder (yellow)
- ✓Beetroot (1 small — grated or boiled)
- ✓Marigold petals (dried or fresh)
- ✓Spinach leaves (green)
- ✓Cornflour or rice flour (as the base powder)
- ✓Small bowls, a strainer, and kitchen paper
- ✓Old clothes and newspaper
How to do it
- 1
Ask your child: 'Before chemical dyes existed, how did people make Holi colours?' Let them guess.
- 2
Yellow: Mix 2 tablespoons cornflour with 1 teaspoon turmeric. Stir. Smell it — turmeric has its own scent.
- 3
Pink/red: Grate or boil beetroot. Strain the juice into a bowl. Mix with cornflour to make a paste, then dry it on kitchen paper for 30 minutes.
- 4
Orange: Crush dried marigold petals by hand. Mix with cornflour. The oils in the petals release their colour.
- 5
Green: Blend spinach with a little water. Strain. Mix liquid with cornflour. Spread and dry.
- 6
Line up your finished colours. Compare brightness, texture, and smell.
- 7
Ask: 'Which colour was easiest to extract? Why do you think marigold was traditionally used for Holi?'
💡 Tips for parents
- →Turmeric stains skin and fabric — use old clothes and wear gloves when handling.
- →The dried natural colours are safe for a small-scale Holi play session outdoors.
- →Extend the science: test whether each colour changes when you add a drop of lemon juice (acid) or baking soda dissolved in water (base) — turmeric turns red with base, which surprises children.
