A crystal of potassium permanganate was carefully introduced at the bottom of water column held in a gas jar. After sometime, the whole volume of water was coloured. Explain this observation

​A crystal of potassium permanganate was carefully introduced at the bottom of water column held in a gas jar. After sometime, the whole volume of water was coloured. Explain this observation (2mks)

​The continuously moving water molecules hit the crystal from all directions causing it to split into the tiny particles of which it consist. The same movement caused the particles to diffuse to all parts of the liquid, this rendering the whole volume colored.
