Although when talking about raindrops we come to mind the image of a tear, the fact is that despite being both liquid the physical form they present is different.
The small drops that have formed inside the cloud, begin to collide forming larger droplets.
Approximately 1 million of the small drops are needed to be able to form a drop of rain, and as they grow they become heavier, stop floating and begin to fall, in the form of rain.
If the droplets are small, their shape is spherical; If they are large, the bottom is flat and the top somewhat rounded, with some form of hamburger bun.
This is because it falls through the interior of another fluid, the air, with which it rubs.
The speed of a falling drop increases if it was large, but only up to a certain limit.
If it is bigger, the resistance to the wind grows, which slows down its fall and the drop deforms.
A tear has a different shape because it falls without there being more resistance, as it happens with the rain that runs into the air.
The reality is that both rain and a tear will depend on how much and where they fall to determine its shape.
Imagine an experiment in which you cry with a fan over your face to see the effect that the air has on your fall, it really is not very advisable because that could hurt your eyes, since the tears come hot from them and the cold air could Cause a temperature shock.
According to meteorologists, rain is not in the clouds. The rain is, in fact, a cloud that falls apart.
The cloud moves in drops when they make the clashes between your microdrops.
Just imagine, anyway the point is that the shape of the water falling depends on the wind and the surface by which it slides.
