This great gray cup insulator is a design that traps the heat inside the cup and it also helps keep the water in your cup stay warm! To use it, wrap the cup with the gray cup insulator, (the side with the circle goes underneath to warm up the bottom of the cup) then put on the cap.  Our group and I also designed a hole in the cap for a thermometer to go though. (To test the temperature) I am very proud that we only reduced 10.3ºC. What I would change is to wrap the cap using 2 more layers of material because we didn’t have time to cut and glue on more layers. The hardest thing about this project is that we have to work out the dimensions and make sure that it fits the cup.
