    The oxygen of one water molecule makes a hydrogen bond with the hydrogen of another water molecule. Likewise, the hydrogens of the first water molecule form hydrogen bonds with the oxygen of 2 other water molecules and this extends throughout the body of water.

    So the water molecules all join together and almost form a skin?

    How does that differ to surface tension?

    The point is that the water molecules are strongly bonded to each other at more than one point.

    This means that water has a relatively high surface tension.
