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.

What materials would be good to use on the outside of the cup?

i agree, most of those answers were NOT helpful. I assume you do not mean a thermos per se, but an insulated container to carry something hot or cold in....that is easy to do. First, get a liquid container with a tight lid (won't leak). Take some insulating material - newspapers, fabric layers....I find that polar fleece works really well. Wrap your liquid filled container in the insulating material, then place in a bag or other container large enough to contain both. The insulation will keep your hot (or cold) liquid hot or cold for quite some time.

On a side note, you can improvise a fireless cooker/haybox cooker the same way (I cook in one all the time).
1. Bring the food you want to cook, say rice, to a boil in a pot with a tight fitting lid and no handle that sticks out very far.
2. Boil 10 minutes.
3. Wrap in 3 inch thick layer of insulation (polar fleece, polyester filled quilt, etc)
4. Let it sit - up to 4 hours - the food will finish cooking without further attention or fuel.
5. Open it up, and eat.
I have used the wrap cooker to make many items, just have the food cut in 1 inch pieces, and be sure it boils that 10 min to get it heated thru. My favorite things to cook this way are pre-soaked dry beans/pulses, cut up vegetables (carrots, potatoes, and the like) and stews of meat and cut up vegetables. Its so easy it is embarrassing. And it all uses the same thermos principal.
