For this experiment we took a soda out of the refrigerator, opened it, put a digital thermometer in it, and recorded the temperature every 30 seconds, for 35 minutes.
Then wrapped the Cheetos around a cold can.
Since the can had been out of the fridge for a while as we wrapped our Cheeto insulation around it, we put the can back in the fridge for 30 minutes to let it cool back down. We then took it out and followed the same procedure, measuring the temperature every 30 seconds for 35 minutes.
For the last part of the experiment we put a can in a foam can holder designed for the purpose of keeping cans cool. We expected this to work the best.
During the first 10 minutes of all of the experiments the temperature of the soda fluctuated up and down. We think this had to do with the carbon dioxide bubbles being released from the soda. (If we were to do the experiment again we would use plain water.)
This charts shows our measurements of the temperature rising over time.
