What can paper do? Consider this book an interactive field guide to the invisible: play with aspects of our world that are usually abstractions, like light, sound, time, and space. Read more Includes six functional pop-up paper contraptions: A musical instrument Sound is produced when something physical vibrates the air surrounding it—whether that object is a string, vocal chords, or a speaker. A decoder ring Substitution is when each letter is swapped for a different character falling a specified number of positions away. A perpetual calendar This perpetual calendar works because it is a wheel—which, like a year, is also a cycle divisible into smaller units.

Here, most of the light is blocked by the paper walls, which reflect the light back into the glowing dome.
