Milk Science Experiment

Today my group and I did a science experiment using milk, food colouring and dish washing detergent.

Materials:

1. 1 saucer
2. 50 ml of milk
3. An eye dropper
4. 2 drops of 3 different colours of food colouring
5. one squirt of dish washing detergent

Method:

1. Grab 50 ml of milk
2. Pour the milk into the saucer
3. Choose 3 different colours and use an eye dropper and put 2 drops of each colour of food colouring.
4. Squirt a drop of dish washing detergent on the middle 
5. See the colour moving and mixing with each other.

Hypothesis- Prediction

I thought the colour will make a swirl and move around separately.

When we put the dish washing detergent it broke the surface tension of the milk and the food colouring, it made the food colouring move and mix together.
