This is the first segment not to be assigned a "Busted", "Plausible" or "Confirmed" rating, as there was no myth to be proved or disproved. Adam and Jamie did the tests simply to dissect the process and determine what actually makes a so-called Diet Coke and Mentos eruption, such as the ones seen on Kari's "FHM" shoot and on EepyBird.com. However, they did compare their results to the many differing theories given by experts as to how the geyser works, "busting" all of them. (None of the theories had the full list of contributing factors for the geyser, only partial explanations.)
