What If?: Serious Scientific Answers to Absurd Hypothetical QuestionsWhat If?: Serious Scientific Answers to Absurd Hypothetical Questions by Randall Munroe
My rating: 5 of 5 stars

The subtitle really sums it up well. Randall Munroe takes ridiculous questions that are submitted to him and does his best to provide scientifically sound, yet thoroughly entertaining, answers. Some examples include whether you could make a jetpack with downward firing machine guns and what would the moon look like if everyone in the world shined a laser pointer at it at the same time. I was familiar with a lot of the questions from his blog, but it had been a while since I read the answers, and it was nice to read some new ones as well.

Definitely the kind of book that I couldn’t put down until it was done, and usually the answers weren’t too long so I could sneak in a few of them whenever I had a bit of free time. I certainly highly recommend!
