Riding roller coasters might help dislodge kidney stones
Preliminary study uses fake kidney to test the idea

Passing a kidney stone is not exactly rocket science, but it could get a boost from Space Mountain.
It seems that shaking, twisting and diving from on high could help small stones dislodge themselves from the kidney’s inner maze of tubules. Or so say two researchers who rode the Big Thunder Mountain Railroad roller coaster at Disney’s Magic Kingdom in Orlando, Fla., 20 times with a fake kidney tucked inside a backpack.
The researchers, from Michigan State University College of Osteopathic Medicine in East Lansing, planned the study after several of their patients returned from the theme park announcing they had passed a kidney stone. Finally, one patient reported passing three stones, each one after a ride on a roller coaster.
