I believe it is cohesion or adhesion.
The property that causes water to form beads is called surface tension.

With most liquids, the attractive force between the liquid and the container is greater than the attraction between the individual liquid molecules. So the liquid "sticks" to the side of the container. A few liquids have a "backwards" meniscus. An example is mercury. If you put mercury in a test tube, it would be higher in the middle than at the edges.

Meniscus is the curve at the surface of a liquid in a cylinder. It is caused by the adhesive and cohesive properties of water molecules. (Meniscus was incorrectly spelled in an earlier answer as "miniscus.")
Adhesion is the property of water causes the curved surface

Hydrogen bonding causes water molecules to connect . The energy required to break multiple hydrogen bonds causes water to have a high heat of vaporization; that is, a large amount of energy is needed to convert liquid water, where the molecules are attracted through their hydrogen bonds, to water vapor, where they are not.
Earth's rotation causes the water to move in a curve; this is a manifestation of The Coriolis force.
The polarity of the water molecule is responsible for most of water's properties.
heat capacity
Only the water evaporates. (At least at reasonable temperatures.)

Expansion of water as it freezes ruptures the cell walls.
