Water is a liquid, and its molecules move around freely, but still must respond to gravity. The molecules in liquid water do not have the ability to hold a shape by rigidly clinging to each other, so the liquid will take the shape of its container.
Well, there is no shape to water. If you have a container the water takes on the shape of the container, but that is not the waters shape, it is the container that the water is in. So even though the water has formed into a shape, it is that containers shape and not the water's shape.

A liquid takes the shape of any solid that it is contained within. For example water within a square container will appear square, but water within a triangular container will appear triangular.
Something that takes the shape of the container it is in. E.g. Water takes the shape of the container which it is in.

People have known long before the invention of science that water takes the shape of its container.
Since water is a liquid, it does not have any definite shape. It takes on the shape of its container.
Ultrapure water stored in a platinum container is neutral.
plastic bottles
at room temperature, water is considered a liquid because it has a definite volume (it does not expand to fill its container like a gas) but not a definite shape (it takes the shape of its container, as opposed to a solid which keeps its shape regardless of the container it is in).
