i am making a thermos. for the bottom; half a water bottle in tin foil to prevent radiation. Then, there will be an air space to prevent conduction and convection. Around the air space i am putting Styrofoam, and I'm wrapping the whole thing in cotton and material. For the lid; i am placing a piece of rubber, then covering it in Styrofoam, and cotton and material. duh!
