A fun experiment to do at home with your kids. If you don't have Acornkids Angel Powder use food colouring instead!


You will need:

food colouring
washing up liquid

Step 1

Pour some milk into a plate or glass dish.

Step 2:

Add some Angel Powder (or food colouring) to the milk.

Step 3

Add a few different colours.

Step 4

Drop a small amount of washing-up liquid onto the centre of the mixture.

Step 5

The washing -up liquid breaks the surface tension and the milk molecules move apart.

Step 6

As the milk moves, the colours run into one another.
