THE COLOUR MOVEMENT

WE NEED

• Three glasses with water
• Paint (red, blue and yellow)
• Paper serviettes

HOW TO DO IT

1. Fill the glasses with water and add red, blue and yellow paint.
2. Roll up two paper serviettes.
3. Put the paper serviettes in the glasses like this.

PREDICTIONS

RESULTS

The process that we can see with this experiment is called capillarity. This is a characteristic of the liquids that makes them go up and down a capillary. It is also the way in which plants absorb the water and the components dissolved in the water to "eat".
The colours aren't mixed up because the second part of the serviette is already occupied by the liquid of the other colour.


OUR OPINION

We like this experiment because is funny and a very interesting thing.
