Colour Splash

Colour Splash on PhotoPeach

MATERIALS:
- 3 glasses
- oil
- water
- food colouring
- a spoon


INSTRUCTIONS:
1)- Fill a glass with water.
- Add some drops of food colouring.
- Water and food colouring mix.
2) - Fill a second glass with oil.
- Add some drops of food colouring.
- Stir with the spoon.
- Food colouring stays a little ball. It doesn't mix.
3) - Fill a third glass with water and some oil (a thin layer).
- Add some drops of food colouring.
- The colouring food drops don't mix and they sit in the oil layer, like floating.


WHY?:
1) - Food colouring is mainly made of water, so it can mix with water.
2) - As food colouring is made of water, it can't mix with oil. It forms balls.
3) - Each drop of food colouring is coated with oil, so the drops float on the oil layer. When you break the oil "coat", they mix with water.
