Here at West Hampstead Nursery we love experimenting!
We have used milk, food colouring and fairy liquid to make the experiment work!
So we poured milk in a plate, we put few drops of different coloured food colouring and them we added few drops of fairy liquid and we observed what happened...
...The food colouring turned into a Rainbow!
''Look Ms. Simona there is a rainbow just like our school is called Rainbow'."
