Cooling Temp

Summary:
• The conclusive evidence from this experiment suggests that the larger the size of the coffee cup, the longer it retained its heat and kept the coffee warm.   The large cup retained its heat the best, followed by the medium cup, and rounded off by the small cup.   From the data collected in this experiment, there was not a significant difference in the loss of temperature between the single cup, and the double cup, although the single cup slightly performed better overall, in all cup sizes, although there is a possible explanation for this stated in the analysis.   If taken theoretically, the data from this experiment may suggest that a larger cup of pop would stay cooler, longer, than a smaller one of similar materials, and lid.
• To better retain its heat, the lid is the most likely part of the cup that needs to be changed, because heat rises, and the lid is the upper most part of the cup that would trap the heat.   A lid consisting of similar cardboard-like materials as the rest of the cup with a similar shape and size as the plastic lids would be a better approach.   A thin wire ring, or some sort of elastic would be used to secure the lid under the lip of the cup, or if production permits, a similar groove as on the plastic lids that fits on the lip of the cup would also work.   The upper portion of the lid would be like a flattened out dome.   On one side there would be a small pinhole to allow for airflow when drinking, and on the other side would be the area for drinking.   There would be a hole for drinking out of, but it would be covered with a flap of similar material as the cup and lid.   Toward the center of the cup, and the pinhole, the flap would be attached to the lid with a permanent adhesive.   Surrounding the hole for drinking out of, the flap would be attached with a temporary adhesive that could be removed and then re-covered by the customer.   The flap would extend over the edge of the lid for ease of lifting it.   The idea is that the coffee...
