Sometimes water seems to defy the laws of physics, holding together despite the attempts of gravity or even the pressure of heavy objects to break it apart.
This is the power of surface tension, a property that makes the outer layer of a body of water (and some other liquids) act like a flexible membrane. Surface tension arises because water molecules bond loosely with one another. Due to the weak bonds between them, the molecules at the surface experience an inward pull from the molecules beneath them. Water will stick together until the forces pulling them apart overtake the strength of those weak bonds, and break the surface.

How warm and cold water mix
Warm water is less dense than cold one. And anything that is less dense tends upwards, while anything that is more dense tends downwards.

Well, maybe, do we have some genes responsible for the degree of a person's industriousness?
It's just that some people seem to lack it, while others have it hypertrophied😁
And if we go deeper into this question, we do find such a pattern in heredity.
The "industriousness" gene (under a slightly different name) is one of the "big five" according to the generally accepted classification of human temperament.
Five complex characteristics have been identified, and they all have high heritability: extraversion, neuroticism, benevolence, openness to experience, and conscientiousness.
Hard work is 40-60% determined by genes🧬
And the remaining percentage is determined by the characteristics of the environment, culture, upbringing. That’s a very high degree of inheritance, and it can have a significant impact on a personality.

Dean's Blue Hole is located in the waters of Long Island (near Clarence Town), Bahamas.
The length of the Blue Hole - 202 meters. Its diameter at the surface is 25-35 meters. From about 20 meters depth it begins to expand to a hundred meters.

Soft robot for exploring the Mariana Trench
Chinese researchers managed to solve the problem of high pressure on the robot body at great depths.
They chose not to strengthen it, but instead made the construction from soft polymer and silicone. The bot's electronics is now distributed all over the robot's body, thus reducing the high load.
As a result, the robot performed well during tests in the Mariana Trench.
