Dr. David Wartinger, a urologist at Michigan State University, looked into the phenomenon after a patient told him he got rid of three of his kidney stones after riding a roller coaster. As a scientist, he decided to dig into the question and set out to check whether his patient's statements were correct.
With the help of his colleague Marc Mitchell, they then made a 3D synthetic kidney, which they then filled with urine and three kidney stones of less than 4 millimeters each. Next step:take the artificial kidney for rides (twenty exactly) on the famous Big Thunder Mountain Railroad at Disney World Park in Florida (where the patient had made this observation). Result:this experiment was more than conclusive for the silicone kidney. Indeed, by sitting at the back of the train, 64% of kidney stones were expelled against 16% by sitting at the front. Small precision all the same, this discovery does not work in all attractions, for the moment only Big Thunder Mountain has proven effective!
It remains to be seen whether this somewhat startling discovery will hold true for human kidneys, which probably don't work the same way as an artificial kidney. A treatment based on amusement park and roller coaster, you can hardly do better
