1. Give your pre-schooler a small empty jar and let them collect small flowers and petals from a garden or they could select from a pile you have already collected.
2. Try to pick flowers, petals or leaves with a strong scent - e.g. lavender. Add a shake of glitter on top of the petals.
3. Fill the jar with water then close the lid.
4. After a few days, scoop out the petals and flowers leaving a glittery liquid.
