This Rube Goldberg machine makes sheer delight out of the process of mixing a Falling Water ( 30mls (1Oz) 42BELOW Feijoa Vodka, lemonade, long slice of seedless cucumber, ice) -- it comes from Joseph Herscher, the same genius who made the Cadbury Creme Egg smasher. Link (Thanks, Sacha!)

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.
