Material:
- Nanoparticles of gold
- Watch glass
- Distilled water
- Water with sugar
- NaCl
Procedure:
The nanoparticles of gold change their color when we change the aggregation.
- Take the watch glasses with nanoparticles.
- In the first one put distilled water (don't change the color).
- In the second one put water with sugar (don't change the color).
- In the third one put NaCl (change the color).

Question:
Why change the color when we put NaCl?
Because the nanoparticles of gold do the aggregation and success the recombination of the nanoparticles.
