Science Buddies: "Ask an Expert"

I am doing a science fair on insulating water with different materials, and I was hoping you could really quicly answer some questions. The insulators I'm using are: A cotton shirt, aluminum foil, Styrofoam, and a wool piece of clothing. I was wondering if you could answer if these are good answers and why or why not? This interview is due tomorrow, and I was wondering if you could respond within around an hour to an hour and a half, or by 7:30 A.M. Pacific time tomorrow morining. Thanks. Also, could you give me your name and profession and why you are an expert in this area. Sorry for pushing this on anyone to late.

I would be more than happpy to answer your questions, but unfortunatly, I do not see any questions in your post.
