How We Tested Insulation

To test the insulation performance of each thermos, we filled them with hot water and measured the temperature at regular intervals over a period of several hours. We also tested the thermoses with cold water to see how well they could keep drinks chilled. Our testing methodology involved:

Filling each thermos with 180°F water
Measuring the temperature of the water at 30-minute intervals for 6 hours
Recording the temperature readings and calculating the average temperature loss per hour
Repeating the test with cold water to evaluate the thermoses’ ability to keep drinks chilled
