Fill a glass with water above the rim. it forms a domed surface. add a paper clip and watch it float, even though the paper clip is made of a metal that is denser than water. this is due to water's surface tension. water has several very unique properties, like surface tension, cohesion, and adhesion because water a) is the universal solvent and can hold anything, even paper clips. b) is polar and every water molecule electrically attracts the neighboring water molecules. c) bonds like metals so water molecules forms crystal lattice structure when in a container. d) is polar and tends to attract metallic substances like the material that makes up the paper clip.

Water has several very unique properties, like surface tension, cohesion, and adhesion because water (B) is polar and every water molecule electrically attracts the neighboring water molecules.

Explanation:

The surface tension is the ability of a liquid to resist an external force. In water, it is possible because of the cohesion between water molecules, which are polar. The attraction occurs between all neighbor atoms. Surface molecules have fewer neighbor atoms (they do not have neighbor molecules above them), then the attraction between surface molecules is higher than in the rest. 

For this reason, you can watch a paper clip floating in a glass filled with water is the paper clip is added carefully. However, if you agitate the water of force down the paper clip, it will sink because you broke the surface tension.
