Hack a Cardboard Box into a DIY Solar Oven

From Lifehacker: "Eco-friendly weblog The Daily Green details how to turn a cardboard box into a DIY solar oven for a little weekend fun in the sun. All you'll need is the box, some construction paper, tin foil, plastic, and a few other items you're likely to have around the house, and when you're done you'll have a full-fledged cardboard cooker."
