Some interesting water facts include:

- The overall amount of water on our planet has remained the same for two billion years.
- There are two kinds of water; salt water and freshwater. Salt water contains great amounts of salt, whereas freshwater has a dissolved salt concentration of less than 1%. Only freshwater can be applied as drinking water.
- Water consists of three atoms, 2 Hydrogen atoms and an Oxygen atom, that are bond together due to electrical charges.
- The weight of a water molecule depends on the number of moles present, as it is 18 grams per mole.
- Water moves around the earth in a water cycle. The water cycle has five parts: evaporation, condensation, precipitation, infiltration and surface run-off.
- In a 100-year period, a water molecule spends 98 years in the ocean, 20 months as ice, about 2 weeks in lakes and rivers, and less than a week in the atmosphere.
