What happens when you add fresh water to salty water?
You can’t see it… but if you colour the water you can see distinct layers!
We started with blue salty water, then we slowly added in fresh green water!
It forms Two distinct layers as the salty water is denser so it sunk to the bottom! The fresh water is less dense ( has less matter in it) so it sits on top!
Then I gave Harry the challenge of creating a 3 layer test tube!
Can you do it? Answers below!
