Why are small water droplets cylindrical?

Water drops are not always round.

1.

Water droplets suspended in the air (such as water droplets in fog) are round; this is due to the attraction between water molecules, the surface tension of water, and atmospheric pressure. The force of atmospheric pressure on an object is equal in all directions, thus keeping the water droplets round.

2.

Falling water droplets are not necessarily round due to the obstruction of air molecules. Anyone who has seen high-speed photography should know that water droplets are "semi-irregular, semi-regular" in shape. It is said to be "semi-irregular" because it is not exactly a bead shape. It is said to be "semi-regular" because it does not have rhombus or right angles, only rounded "corners". This feature is caused by the attraction and surface tension between water molecules.

3.

The shape of water in a vacuum, as we can see on TV, is not necessarily round. It is controlled by the attraction and surface tension between water molecules, and it lacks the atmospheric pressure. Equal role.

My statement: Researching science should be done with a rigorous attitude. I wrote the following comments for the benefit of the public. I apologize for any offence.

1. The effect of gravity on each molecule of an object is unequal.

2. The planets in the universe are all round, so the water droplets are also round. Haha, so every object on the earth is round. Planets are large enough to generate internal gravity and there are no external forces in space (there are exceptions), so they form a round shape. Small objects in the universe such as cosmic dust, debris, and meteorites are irregular in shape. Compared with the size of a water droplet, the size of the planet is completely different!

3. Some people say that ""gravity" has nothing to do with the fact that water droplets are spherical", but later they mention the "center of gravity", which is directly related to gravity. "Water molecules will also move slowly" is wrong. In fact, it will happen in an instant, otherwise our naked eyes would be able to see the process.

"The circle occupies the smallest volume and suffers the least resistance when falling" - why just for falling? Isn't it spherical when suspended? Why just reduce resistance? Could it be that the water droplets know this and adjust their shape on their own? That sentence is a "result", not a "cause".

5.

"How can it be square if there are N circles tightly together?" - It should be said "many", not "N many". If it is not a liquid but a solid, multiple spheres can be gathered together to form various shapes. Seen from a distance, they may be rectangular or spherical, depending on molecular suction, gravity, atmospheric pressure and other external forces. If it is a liquid, explain it as above.
