The hardest thing about this project is to combine materials together, find out which material can be used in our project. We also struggled a bit in deciding what materials are we going to add on the outside and which will be the inside layer. I think our cup design fits perfectly on the cup, all the materials made a big help to our design. 6 layers of cotton and felt can keep the temperature stay warm, color and outlook are plain but it is useful. For the cup-dressing we used cotton and fabric, you can take the warming code off if needed(to wash/or cold drinks) Thermal energy transfer is the main idea we are learning. I learned a skill about adding materials together, put materials that can keep cool together, as well as add materials that can hold heat together, it will work better on our prototype.
