Hi, I was wondering if anyone could help me decide on which material i should use. I am looking for a material that has a high specific heat and does not radiate (any or very little) heat from the sun. This material would need to be relatively cheap and easy to obtain. Some one told me that styrofoam may work well because it does not radiate very much heat from the sun, but im not sure about that idea. If anyone has any other ideas on what i might be possibly looking for please let me know. Thanks
