Is lava water, and could we have a delicious hot cup of it? Is ice really a rock, and not water? And, the age old question, is water wet?

From the minerals that shape the taste of our favourite drinks, to the tiny isotopes that reveal where a person, or whale, has travelled, Professor Hannah Fry and Michael Stevens reveal the hidden life of H₂O.

Along the way, they uncover why pure water can be deadly, how yesterday’s sewage might be fuelling the future, and discover that the water in your glass might be older than the Sun.

Prepare to rethink the world’s most familiar liquid - it’s far stranger, rarer, and more extraordinary than you ever imagined.
