Clare and I both love combining Science and Art. The children are engaged, learning and it's so much fun. We decided to make milk prints!
We posed the question "What would happen if we were to mix milk, food colour and detergent?"
We were all amazed by what happened. We placed milk in the tray and then added some drops of food colour. Nothing happened..... but then we dropped a few drops of detergent and that's when the magic started!
All the colours started moving and mixing and twirling creating brand new colours and swirls. We dipped our watercolour paper into the mix and tada! A beautiful piece of art, each unique for every child.
So... What's the Science?
Milk is mostly water but it also contains vitamins, minerals, proteins and tiny droplets of fat. The secret of the bursting colours is the chemistry of that tiny drop of soap. Dish soap weakens the chemical bonds that hold the proteins and fats in solution. The molecules of fat bend, roll, twist and contort in all directions as the soap molecules race around to join up with the fat molecules.
So much learning, beautiful prints and in the words of the children, "Magic".
