Until now we thought that the raindrops were teardrop-shaped (and we have drawn them hundreds of times and they are also represented in this way in weather forecast maps), but the NASA claims we were wrong.
According to the researcher from the US space agency, Chris kidd, the raindrops are not shaped like a teardrop, but rather like a hamburger bun, because as they fall they become "heavier and heavier".
Chris Kidd explains that raindrops They go through three different phases, and in none of them do they resemble a tear. Initially, they form a small balloon that allows molecules to bond with each other.
The first of the transformations occurs as the raindrops fall to the surface. The pressure of the earth pushes from below and distorts its shape, leaving it round on top and flat underneath, like hamburger buns.
The third phase occurs just before the drop breaks up into smaller drops. At that time its shape has been compared by this NASA scientist to that of a parachute.
Said like this, it seems like a discovery without much relevance, but Chris Kidd assures that it can be put to many uses, especially in understanding the weather patterns: "In the case of floods, the information can be used to advise emergency services and make them work more efficiently and it is also very useful in aviation, to guide aircraft at airports during a storm."
