Combine glowstick gunk and diamond glitter in a sealed jar and shake -- voila, fairies!
It's a fake. But this one isn't. Same idea: glowstick gunk in jar (no glitter).Thanks to commenter BeckyLikesOwls for the tip!

I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
