Dont give me the answer that its because of surface tension. I want it in detail.

Why come here to be told to go to Google?
Perhaps you came here from Google !
Very sloppy, no use at all.

I browsed elsewhere and found out that it tries to minimize the area to attain the least possible potential energy. Thus its surface will try to have minimum molecules thus making its exposed area stretched.
The surface of a liquid acts as a stretched membrane due to the force of surface tension. This is caused by the attractive forces between the molecules of the liquid, which pull the surface molecules towards the center, creating a stretched surface.
The surface tension of a liquid is caused by the intermolecular forces between the molecules. These forces, such as hydrogen bonding or London dispersion forces, create an imbalance of forces at the surface of the liquid, causing it to behave like a stretched membrane.
Surface tension affects the behavior of liquids by creating a barrier at the surface. This barrier can prevent objects from sinking or floating, cause droplets to form, and allow insects to walk on water. It also plays a role in capillary action and the movement of liquids through narrow spaces.
No, surface tension varies between different liquids. It is influenced by factors such as the type of molecules, temperature, and presence of solutes. For example, water has a higher surface tension than most other liquids due to its strong intermolecular forces.
Surface tension can be measured using techniques such as the drop weight method, where the weight of a drop of liquid is measured as it falls from a capillary tube, or the du Noüy ring method, which measures the force required to pull a ring from the surface of a liquid. Other methods involve using specialized instruments such as tensiometers or surface tensiometers.
