Milk, Detergent & Food Colouring Mashup

In science we observed items when 2 (or more) substances are mixed together.

Items needed -

> Plastic Container/Dish

> 50 ml Detergent

> 200 ml Milk (with fat)

> Eyedropper

> 4 Different Colour Food Colouring

Method -

1. Pour milk into plastic dishDrop 3-5 drops different food colouring onto each corner on dish using eye dropper
2. Clean inside of eye dropper or use spare
3. Drop 3 drops detergent on middle of milk
4. Observe what happens next

What really happened? -

In the detergent, it is made up of certain chemicals that cut up fat. When the detergent is in the milk it starts to create a small spiral-like ripple that is not visible to the eye since the milk is pure white. When food colouring is added, it can show what happens in the milk when the fat is being cut up.
