Liquid Rules is nonfiction. I bought my copy new.
Review:
Miodownik discusses a wide variety of liquids - their molecular structures, properties, and ways we use them - using a flight from London to San Francisco to help guide the book's organizational structure.
The first chapter, which deals heavily with kerosene, had me thinking "this is exactly what anxiety feels like." The pre-flight safety briefing had just begun, and all Miodownik could think about was the tens of thousands of gallons of kerosene on board. That topic inspired him to write about wicking, surface tension, and other topics, but, in the end, everything circled back to kerosene. It reminded me, keenly, of unsuccessful efforts I've made in the past to yank my thoughts away from whatever I was anxiously obsessing about.
