Thrive's Nike has a recipe for making rainbow-striped jello Easter Eggs, using Kraft's "JELL-O JIGGLERS Egg Mold." She advises coating the mold with generous amounts of cooking spray, then using a syringe to add layers of color, chilling for 10-15 minutes between each layer.
I still remember fondly filling blown eggshells with liquid jello and letting them set in the fridge in an egg-carton, making "hard boiled eggs" that were filled with jello instead.
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.
