It makes sense that water always seeks its own level. Water is a very heavy substance.
.
The heaviness of water has nothing to do with the first statement. Only under particular conditions does water seek its own level. There must be a confinement, for example. Water unconfined and in a free-fall environment does not seek its own level, but floats around in the air eventually forming a sphere or a globe. This globular action is due to the cohesion of the water molecules as well as the inherent surface tension , and it happens to any liquid substance in the same situation, none of which "seek their own level."
.
Surface tension is a phenomenon which causes the meniscus in small samples like a drinking glass or a test tube, under different conditions such as those found on the surface of the earth, such as a common laboratory.
.
These substances, such as oil or mineral spirits (which are lighter than water) also form a globular sphere, and
do not seek their own level; so do mercury or liquid iron (both much heavier than water).
.
Therefore the statement that
"water always seeks its own level" is
false.
.
If this were your answer on a basic physics class test you would get marked off for being incorrect.
.
Flat-earthers would do really poorly in any basic physics class.
.
There are no physicists who believe in a "flat earth." They would have to be literally insane first.
