Water drops forming round in shape always, not in square shape or not triangular in shape.

water droplets are only perfectly round in conditions of zero gravity and with no breeze or wind to distort them. Under normal conditions on Earth they would be "fatter" at the bottom and when falling as rain they adopt teardrop shape, a bit like a pear shape.
to get square or triangular drops: freeze them and then cut to shape - simple!

Some people must be living in a comic book world. Water drops only have that "little tail fin" in drawings. If you look at photographs of water drops falling, you will see that they are spheres that have been pushed out of round by air resistance.
Surface tension causes water drops to be the shape that has the minimum surface area for the volume of the drop. That shape is a sphere. It's the same reason that soap bubbles (when not affected by external pressures) are spherical.

Rain drops are humidity condensed around a small speck of dust. I've heard somewhere that clouds are just dust and the average cloud weighs as much as an elephant(!) the water condenses around the speck of dust and surface tension keeps it in a spherical shape. Rain becomes wing shaped because of the high pressure in front of it and the low pressure to the sides and behind it.

the same reason every liquid forms in a round shape, because this is the way in which the laws of physics apply themselves to a liquid.
On the ground, the liquid will spread out into the path of least resistant, until in has totally spread out in every direction, making the pattern round. A drop falling. like rain is subject to the forces of gravity, friction and takes its round shape this way

Surface tension. A sphere is the only shape that balances the forces.

cohesive effect... the surface tension tends to be LINEAR, meaning that the shape will be the SAME DISTANCE from the center... that... ends up ROUND.
It's not that hard to understand.

not perfect spheres.
It is because pressure is exterted on all sides when drops fall.
however because of air and friction drops get that little tail fin on top.

it's all about surface tension. it's the most stable that way since it doesn't like the table it's on so it beads up

it is because of surface tension.surface tension always tend to reduse the surface area.surface area is small when it is spherical.

kohesive. the molekules is interacting.
