Magic Milk

Today during science we made magic milk. By using food colouring and dish washing liquid we were able to make the milk dance!

The dish washing liquid does not mix with the milk. It floats on top and spreads over the surface. As it spreads, it grabs the food colouring. Soap is a "degreaser" so the molecules in it are attacking the fat in the milk, causing motion which creates the swirling of the colours.
