This is my cup and I made it with Linda. I used fabric, foil, and foamed plastic because they can keep the cold outside and keep the coffee hot. The thing that I proud of in this project is I can help cafeteria to keep the coffee hot. The thing I would do differently is I will create more good materials and a good temperature probe because of the temperature of the water was very hot, so the liquid in the probe came out and mixed in the water. The hardest part in this project was temperature measure because the temperature probe broked.
