... Water is VERY unique. Water is polar. That is, the oxygen atom in water pulls harder on the electrons than the hydrogens do. So, the oxygen “edge” is more negative than the hydrogen portions. This makes water almost magnetic, so it likes to cling to surfaces. This is called adhesion. Because water i ...
