Our cup insulator was quit good, the temperature only decrease 9 degrees. At the start it was 85.4 degrees and after 10 minutes it was 76.4 degrees.  Our temperature after 10 minutes is actually higher than the Control one’s, even though we were lower than the Control at the start. The hardest thing was we have to find the materials and we also have to keep track of the time so we have to do it quickly.
