joy and I designed this cup set insulator that is capable of keeping  the heat inside the mug, the materials we used were fabric that raps around the mag , mylar raped inside the fabric , velcro to make them attached, the lad was made of some thin fabric and inside had mylar to keep heat in side the mug.

I am proud of being a part of the saving penguin unit and helping to solve variety problems,The hardest thing about the project was when we had different ideas and argument. I think the quality of our cup is very good and we improved on the insulation part of the work.
