Demonstrating how rain falls from a cloud!
Shaving cream - food colouring and a clear jar of water is all you need for this demonstration.
Spray some shaving cream on top of the water and then drop on a few drops of food colouring.
Voila - it's raining! It takes a few seconds for the food colouring to makes its way through - be patient.
I saw this HERE and quite a few other places - I knew we had to try it!
