Bomb calorimetry is arguably one of the most common physical chemistry laboratories performed in the undergraduate curriculum. These studies introduce the analysis of common candy bars, specifically Kit Kat™, using bomb calorimetry. The results showed excellent correlation to the Caloric content of the candy, thus giving a "real-world" application to a technique that is often viewed by students as purely academic. Accuracy, precision, and sampling were also investigated in this laboratory experiment.
