Inside that bottle is water. That water is probably not pure water, but it is water. Water molecules are made up of three atoms, two hydrogen atoms and an oxygen atom. The oxygen atoms is more electronegative than either hydrogen atoms. This electronegativity attracts more electrons, which makes the ooxygen more negative than the hydrogens. This is described as polar, or as a polar covalent bond. Anything that is polar is also hydrophilic. This means that it will attract to other polar molecules. Hydrophilic describes this relationship. Hydro whcih means water and philic which means love describes how any polar molecule is attracted water (another polar molecule). This can be seen even when you are not looking on the molecular scale. A hydrophilic substance easily dissolves in water.
