It's a GasThe secret life of gases the strange, elusive and fascinating substances that shape our world, from the author of the best selling, prize winning Stuff Matters. Why are most gases invisible, odourless and tasteless? Why do some poison us and others make us laugh? And why do some power our engines while others make drinks fizzy? In It's a Gas, Mark Miodownik masterfully reveals an invisible world through his unique brand of scientific storytelling.
