My original hypothesis was not correct. I thought that the Dr. Pepper and Mentos fountain would go as high as or higher than the Diet Coke fountain because there is more carbonation in Dr. Pepper than there is in Diet Coke. The Diet Coke’s average fountain height with mint Mentos was 649.9 mm. The average fountain height with mint Mentos and Dr. Pepper was 472.0 mm. However, there was one Dr. Pepper and mint Mentos trial that had a fountain height of 698.5 mm, which is in line with the fountain heights of Diet Coke and mint Mentos. Across the board, the fruit Mentos did not create as high of a fountain as the mint Mentos, regardless of the type of pop.
