HOW TO – Make a Thermal Carafe

Drew writes “I used some discarded beverage bottles, aluminum foil, duct tape, and expanding insulating foam to make a thermal carafe for next to nothing. Then I tested it against a real Thermos and an uninsulated bottle to see how it compared. Conclusion: a thermos made from junk isn’t quite as good as a store-bought one, but it’s much cheaper and a lot more fun.” – Link.
