Water is made up of two parts Hydrogen and one part Oxygen… H2O.
Water is the most common substance on Earth, but 97% of it is salty and not safe to drink. 2% of the water on Earth is frozen in glaciers and ice caps, leaving only the remaining 1% for us to drink!
Water is the only substance on Earth that exists in all three forms – as a gas (steam), a liquid, and as a solid (ice).
The same water as is on our planet today was here when the dinosaurs drank it! It has been recycled millions of times!
