In the case of milk, after coming out of the bottle, it(milk) directly takes the shape of the container while on the other hand glycerine barely takes shape, and that too after a very long duration. You will also observe that the contact timing between the air and glycerine is too long when compared to that of milk and air. Also, a good amount of glycerine settles on the surface of the bottle while pouring out. You will observe that speed of glycerine coming out of the container is too slow compared to the speed of flow of milk coming out of the bottle. Now, take another similar bottle filled with glycerine this time and pour it into another container. You will also observe that the contact between air and milk is for a concise duration. You will observe that the speed of milk that is flowing out of that bottle is too fast, and it barely settles on the surface of the bottle or the surface of the neck of the bottle. Take a bottle filled with milk and then pour it into another container. Let us now take another instance to make it more suitable to acknowledge. On the other hand, honey is a dense, dark-coloured, and semi-fluid substance with a very high internal resistance to flow, barring the momentum transfer causing it to flow sluggishly and resist deformation described as having high viscosity. The observation in the first situation where the main subject is water arises as the low inner resistance of water to remain in motion led to its momentum transfer very easily, inflicting it to shear it without any difficulty and the quick flow of its molecules described as low viscosity. The question, why water flows so fast while the speed of flow of honey is too slow as compared to water must have aroused in your mind. The most basic thing you must have noticed about these fluids would have been the difference in their speeds. Similarly, we use fluid like honey in our regular or monthly diet plan because of the benefits we get from multi-nutrients present in it.

Water being the basic necessity of our daily life, is used by us for multipurpose from drinking for clenching our thirst to bathing, cleaning, cooking and other daily activities. Low viscosity fluids are those whose viscous forces are much low or negligible compared to other fluids also, the molecular formation makes its friction little or almost frictionless, causing the movements of fluids too fast. The fluids which have low internal momentum resistance and do not resist deformation are called low viscosity fluids.
