On Friday 16th March, Year 2 investigated what happens when you mix milk, food colouring and washing up liquid together.
Fist we carefully poured milk onto a plate.
Then we dropped different coloured food colouring on to the milk. We used orange, blue and pink food colouring.
Next we put a cotton bud the was covered in washing-up liquid into the centre of the plate.
We observed how the food colouring moved around the plate when we touched the milk with the cotton bud. This is because the milk contains fat, the washing-up liquid bonds with the fat in the milk and the food colouring is pushed out because the bond is so strong.
