1. Take a beaker with water. Mark the level of water.
2. Add 1 or 2 crystals of potassium permanganate and dissolve in water.
3. Colour of water changes to light violet.
4. Now take out approximately 10 ml of this solution and add it to 90 ml of clear water in another beaker.
5. Now the colour of water will be lighter than in the previous one.
6. Again take out 10 ml of this solution and add it to another 90 ml of clear water.
7. Carry out this process 4, 5 times and observe the changes in colour of the solution.
8. We observe the water in last beaker also changed to light violet.
9. From this activity we conclude that both solids and liquids are made up of tiny particles.
