The idea
A liquid is a state of matter that flows and takes its container's shape while keeping a nearly fixed volume.
In practice
Cooking oil poured from a tall bottle into a wide bowl changes shape instantly but occupies the same volume in both.
Where people slip
A liquid's flat surface under gravity is not intrinsic — in zero gravity the same liquid pulls into a sphere.
