Add some crystals of blue vitriol (copper sulphate) and dissolve them in 100ml of water. The solution will go blue. Keep on adding 100ml of fresh water, repeat this 5 to 8 times. The last solution is till blue though the intensity of the colour has gradually decreased. This indicates that a few crystals of copper sulphate are able to colour an enormously large volume of water. This also shows that a small crystal of copper sulphate contains millions of small particles.
