Why can't we observe the movement of water though the molecules of water are in continuous motion?
Clean water /Distilled water is not a colloidal solution. So we cannot observe Brownian movement in water.
Brownian motion (or Brownian movement) is defined as the continuous and random motion of the particles suspended in a liquid or in a gas. It is caused by the collision of these particles with each other and with the molecules of the surrounding medium due to their random movement with varying velocities. Brownian motion is observed in colloids.

Particles in both liquids and gases (collectively called fluids) move randomly. This is called Brownian motion. They do this because they are bombarded by the other moving particles in the fluid. Larger particles can be moved by light, fast-moving molecules.
Brownian motion is named after the botanist Robert Brown, who first observed this in 1827. He used a microscope to look at pollen grains moving randomly in water. At this point, he could not explain why this occurred.
But in 1905, physicist Albert Einstein explained that the pollen grains were being moved by individual water molecules. This confirmed that atoms and molecules did exist, and provided evidence forparticle theory
