Magic Milk

Enjoy the wonders of chemistry with this easy to do kitchen activity! All you need is milk, food colouring, and dish soap. No two magic milk experiments will ever be the same!

Pour the milk into a baking tray or other flat bottom surface, just enough to cover the bottom and then some. Fill the top of the milk with drops of food colouring. Feel free to mix the colours together!

Dip a cotton swab or your fingertip into dish soap and gently touch the surface of the milk. Watch what happens! All the colours should swirl and scatter! Different types of milk will show different effects, due to the varying percentage of fat and protein, which are sensitive to the dish soap.
