We are going to learn about surface tension with liquid.
Proucure
What you need:
milk
saucer
food colouring
detergent
What to do: First fill the saucer with milk. Pour one drop of every food colouring on the milk, around the edge of the saucer. Put one drop of detergent in the middle of the saucer.
The food colouring will start to go around the saucer.
I predict the detergent will make the colour go into a new colour and make the colour around it start to swirl and mix colours.
What happened
When you put the detergent in the milk it makes the colours swirl around, make the colours into a different colour and gets smaller.
