Why is the sky blue and the sunset red? It’s all to do with light scattering and the Tyndall Effect.
This experiment demonstrates light scattering. By shining a light through a jar of water containing a little milk you can see the different colours in the light are scattered in different directions. For full experimental details please view the Tyndall effect instructions.
