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
is the universal solvent and can hold anything, even paper clips.
is polar and every water molecule electrically attracts the neighboring
water molecules.
bonds like metals so water molecules forms crystal lattice structure when
in a container
is polar and tends to attract metallic substances like the material that
makes up the paper clip.
