What is the magic milk experiment?

In this magic milk experiment the milk and food coloring form a little dome. However, when dish soap is poured over the surface, the surface tension is broken because the dish soap breaks those bonds. This causes the colored milk to spread out like a flood over the surface of the milk.

What happens if you put food coloring in milk?

When liquid dish soap is added to milk with drops of food coloring on the surface, the soap reduces the surface tension of the milk and reacts with the fat. This interaction causes the fat particles in the milk to move and create swirls of color.

What does soap do to milk?

Once the soap is added to the milk, it spreads over the surface and causes the food colouring to move quickly thorough the milk and out to the edges of the plate. Since milk is mostly water, it has a surface tension like water. Liquid soap wrecks the surface tension by breaking the bonds between water molecules.

Is soap attracted to water fat or both?

The molecules that make up soaps and detergents have two main parts (ends) that behave differently. One end of a soap molecule is attracted to water, while the other components are repelled by water but attracted to fats.

How do you make magic milk?

  4. Watch in amazement as the colors dances across the surface of the milk.
