''Thing Explainer'' is Randall's second published book, not including xkcd comic books, which he announced on May 13th, 2015 in [http://blog.xkcd.com/2015/05/13/new-book-thing-explainer/ the blag] following the amazing success of his [[What If?

The book is a collection of diagrams and line drawings similar in style to the Up Goer Five comic, which can also be purchased as a poster. It was [[#Release day|published]] by {{w|Houghton Mifflin Harcourt}} on November 24th and is available from among others {{w|Amazon.com|Amazon}} to which [http://amzn.to/1GCXMJ5 a link] has been posted on xkcd for a long time.

On the day of the book's release (even though it was a Tuesday) Randall also released the comic [[1608: Hoverboard]], which was a direct celebration of the book's release (it says so in the comic). But it was far from being a small or normal comic! It was the first "real" game comic released on xkcd (albeit not the first [[:Category:Interactive comics|interactive comic]]). In the style of [[1110: Click and Drag]] it was possible to move around in a very much larger picture than what was shown in the frame. But this is not done by clicking and dragging though, instead the user controls [[Cueball]] on a {{w|hoverboard}} (hence the title of the comic) by using the arrow keys, assuming that the user is on a desktop computer or a laptop.  If they are on a mobile device such as a smartphone, [[Cueball]] is controlled by tilting the device.

There are many themes and references throughout the game, but the two main themes are {{w|Star Wars}} (the largest part to the right part) and {{w|The Lord of the Rings}} to the left. Several references goes back to the book from this comic. These are [[1608: Hoverboard#Reference_to_Thing_Explainer|listed in the explanation]] for the hoverboard comic.

How do these things work? Where do they come from? What would life be like without them? And what would happen if we opened them up, heated them up, cooled them down, pointed them in a different direction, or pressed this button? In ''Thing Explainer'', Munroe gives us the answers to these questions and so many more. Funny, interesting, and always understandable, this book is for anyone—age 5 to 105—who has ever wondered how things work, and why.
