The history of sneezing powder is unexpectedly fascinating, a tale of an obsessive prankster, whose burning passion to make people sneeze drove him to out-and-out chemical warfare:
No one's entirely sure what Adams used to make Cachoo. It depends on what he had easy access to. He worked for a company that made coal tar products, specifically dyes. Coal tar is what gets leftover when coal is made into more purified fuel. It's a viscous black substance that can be used to pave roads, but is also added to medicated shampoo, and used as a base for clothing or even food dye. There are plenty of by-products in the process that can - but probably shouldn't - be used as nasal irritants. These would be easily accessible, and, if they were by-products, cheap to acquire.
But more recent chemists think that to make Cachoo, Adams was actually pilfering one of the dyes that he was supposed to be selling. Dianisidine is a chemical that, with coal tar, makes a beautiful blue dye. It's also carcinogenic and, according to the CDC should be flushed from every part of the body it makes contact with. A sneeze response would certainly help with that. Dianisidine was first discovered in 1894, when people noticed that it, in combination with copper salts, made a pretty color on fabrics that set in faster than indigo. People would have been using it a great deal, especially in the manufacturing centers, testing out new products.
Unfortunately, over a few years they found out that it ran when exposed to acid, or even heavy perspiration, bleeding blue on anyone who wore clothing dyed with it. Its color might have worked for soap products, but it was useless in clothing manufacturing. The repeated testing, would have given Adams ample opportunity to see people sneezing. The eventual abandonment of it as a potential clothing dye may have given him the ability to pick it up at a good price for his initial stock of Cachoo. But is that what he did?

Life is a continuing cycle of newness, then growth, and then gone: then birth and growth again. I started thinking about that theme of new life and new beginnings several years ago, and WAKE UP!, published by Candlewick Press, is the result. Working with my collaborator, poet Helen Frost, our book is about opening eyes—our own, first—and pointing to the world that’s right here, containing us all. Helen and I are both based in the US Midwest, so we started there, with a world that we didn’t need to travel far to explore, only wake up enough to actually see.
John Scalzi’s on tour with his new novel, The Collapsing Empire: he’s posted a list of ten things every touring author knows, and very few other people ever get to see.

“Gets stuff done,” is a good way to be described by anybody. Especially by coworkers or bosses. Because whether you’re in finance or a children’s librarian, stuff needs to get done. But how do you make sure stuff gets done? You definitely can’t do all the stuff yourself, unless your company/organization/government office consists entirely of you. And […]
Even the most expensive pair of hi-fi headphones can’t match the feeling of bass rumbling through your body at a live show. That’s why music aficionados designed The Basslet, an accessory that reproduces that sensation from your wrist. Does it make your whole body shake with deep subs? Not really, because that would be terrifying, but […]
