1. Pour milk into a plate/lid |
2. Put 2 drops of 3 colours of food colouring onto the edge of the plate |
3. Put a chop stick in the centre. Does anything happen? |
4. Now dip the chop stick into dishwashing liquid and put into the centre of the milk. What happens? |
The milk has fat in it. The dishwashing liquid breaks down the fat, drawing it towards the chop stick like a magnet, and pushes the food colouring away from it. |
