Household Hacker presents a simple way to make a gorgeous slime from borax and polyvinyl alcohol (buy 'em): "This links the atoms and molecules together forming a molecular net that will trap all the water. This net is what allows the slime to flow slowly as opposed to flowing like normal water would."
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.
