“I don’t really understand why water has so many properties on different scales ranging from very large and cosmic to very small quantum and quarky - Could you help by zooming in and out on water to explain what is known about it? "Asks Neil Morton in Stirling.
“Why does boiling water sound different to cold water?’ asks Barbara Dyson in Brittany in France
Ollie Gordon, in Christchurch in New Zealand, wants to know ‘why water is essential for all life as we know it?’
And many more questions on the weirdness of water are tackled by super science sleuths Hannah Fry and Adam Rutherford.
With assistance from:
* Quantum physicist Professor Patricia Hunt, at the Victoria University in Wellington in New Zealand
* Science writer and author of ‘H2O – a biography of water’ Philip Ball
