I absolutely loved Chris Barton's book, The Day-Glo Brothers, The True Story of Bob and Joe Switzer's Bright Ideas and Brand-New Colors. It's a children's book about the two brothers who invented fluorescent paint and Day-Glo paint. Joe Switzer wanted to be a magician when he was younger and he started fooling around with a black light that he and his brother Bob learned to make from a 1930s issue of Popular Science (I'm guessing it was this PopSci article from 1932).
They shined the light on the chemicals lining the shelves of their father's pharmacy and noticed that some of them glowed vibrantly. They started buying and mixing chemicals and eventually developed a number of different kinds paints that gave fluoresced under black light. Later, after much experimentation, the stumbled on paint that fluoresced under white light, which they dubbed "Day-Glo." The discovery made them very rich.
The book is illustrated by Tony Persiani, and it makes good use of Day-Glo ink, natch.
The world needs more fun history books like this!

There are few intellectual exercises better than a good game of chess against a capable opponent, which is why a lot of old hands at the gameplay it online. But there’s still nothing like the tactile thrill of moving a knight into checkmate. (Or sweeping the pieces off dramatically when you lose.) That’s why we’re […]
Got a real music junkie on your list this year? It’s a good bet that they already have a solid pair of earbuds, but probably nothing quite like these Seeds Earphones. Here’s the thing: Wireless earbuds are all the rage right now, and there are a lot of good reasons for that. But for true […]
When it comes to the qualities of a good project manager, you hear a lot of talk about “soft skills” like leadership ability and confidence. And where does confidence come from? It comes from people who are dead certain they know the right steps to take. In other words, you’ve got to master the hard […]
