Reason is Viscosity.
Explanation :
When water in a container or glass tumbler is set into rotation by glass rod , the rotation starts from co-axial cylindrical layers.
On stopping the rotation by glass rod, the speed of different layers are seen decreasing and liquid finally comes to rest.Which shows that the liquid experiences a internal friction.
Hence Viscosity is the property of fluids by virtue of which an internal resistance or drag[fluid friction ] comes into play when liquid is in motion . The internal friction tries to stop the motion of liquid.
