I am fascinated by water as you may already know, I have been posting documentaries on it for years now. Here is one which links to another documentary called “Water the great mystery”, it’s really worth a watch. And there is also the fourth phase of water. Water can dissolve more solids than any other substance, water has at least 66 properties that differentiate it from most other liquids, and water is almost the only liquid in the universe where the solid form is less dense than the liquid form. Water is really weird, but it has also made life on Earth possible and all its incredible characteristics exist thanks to the hydrogen bond. Water consists of one oxygen atom bonded to two hydrogen atoms: H20. In this Elements, we explore a debated school of thought: Is water actually two different liquids instead of one complicated one? And can this hypothesis actually help us explain water’s strange properties? Watch to find out more!
