Name of the cup:  Clean Black

1. We are proud of making so clean unlike others and make successfully.
2. I would like to make the cap differently because wood’s edge is very sharp and more cleaner.
3. My quality of cup looks clean and accurate measurement.

This is our final product, it is a cup insulator. It prevent the heat loss, so help to drink hot beverage or water longer. This prototype has three layers. One layer is made out of aluminium foil, second layer is made out of felt, and  last layer is made of black paper. Black paper helps to absorb the heat, and aluminium foil helps to reflect heat that comes to the cup. Lastly, felt helps to absorb the heat, too.
