Yet this seemingly basic substance is necessary for all known forms of life, comprises two-thirds of the human body, and covers 70 percent of the Earth. Water also displays a wide range of unique behaviors, such as how it sticks to itself, goes against gravity, and dissolves many other substances.

The wonder and weirdness of water is discussed in this episode with Alok Jha, author of The Water Book. He talks about water’s strange properties, cosmic origins, arrival on this planet, and presence throughout the universe. Alok says that although water is arguably the most studied substance in history, it is also one of the most mysterious.
