What happens when the writer of xkcd puts his mind to common everyday tasks? Hilarity, of course.... and as usual, a lot of fascinating physics.
I would place this in the middle of Munroe's two books. It's far better, funnier, and grown-up that Thing Explainer: Complicated Stuff in Simple Words, but less fresh than What If?: Serious Scientific Answers to Absurd Hypothetical Questions. For all that it's still laugh-out-loud funny, grounded in solid physics (albeit in absurd ways), and manages somehow to change the way you might actually look at problems in the future.
4/5. Finished 12 October 2019.
