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!

Try making a Styrofoam container surrounded in duct tape, or try using fiber glass surrounded in bubble wrap!

Well first you need to get a styrofoam cup and wrap it in aluminum foil then make a glass layer outside with a vacuum that conducts no heat place another layer of metal outside that to reinforce the fragile glass layer and make a cap.
