Hello! This is my cup heat insulator. I designed it with Peter, and Ray. Let me tell you how
it works. Our group first covered the inside with some felt. And then we put a lot of steel wool. Lastly, we covered it with more felt. I will now tell you why I made this project. The teacher’s coffee was cooling, and they don’t want it to. We could have done it more good if we had more time and if we had more materials.
