How to Play

This is a very simple experiment that shows children how plants take water up their stems to the petals (using ‘capillary action’). Depending on which food colourings are used, it can also show what secondary colours can be created – for example, blue food colouring mixes with the yellow of the flower to create a green flower. Here are the three simple steps to create your own amazing rainbow daffodils.

 

1. Half fill a glass with water and add a few drops of food colouring

2. Trim 2cm off the stem of the daffodils

3. Place the daffodils into the glass and leave over night

 

You can try using a few separate flowers so that children can compare the effects of different food colourings, or maybe try mixing different food colours together in one glass to see what happens. Or, try carefully splitting the stem into two lengthways (without cutting the flower head) and place both stems into a separate glasses of coloured water.
