Kari was able to hear Jamie and Tory’s digging in an underground mine shaft in two of the three tests. She actually detected them better by listening to the drum compared to Grant’s use of modern geophone equipment.
This myth yielded a varied number of results, but in the definitive test where the only variable was time the myth was definitively busted. There was no real difference in the amount of bacteria collected from 2 seconds exposure as there was from 6 seconds exposure.
Adam tested this myth just out of curiosity and when the results were compared to the bacteria samples from the “five-second rule” tests, the toilet seat actually proved cleaner than all other surfaces tested.
The sample collected from Adam’s mouth had much more bacterial growth than the sample collected from Lulu the dog. Jamie suggested, however, that the bacteria from the dog may be more potent.
