Why did you use two coffee cups during the experiment instead of just one cup? in case a hole was punctured in the inside cup to add more weight in order to stabilize the calorimeter to hold all of the water in the experiment so that the water temperature would not change at all during the experiment to prevent heat from escaping from the calorimeter
