It's been said that it's more painful to pass a kidney stone than to give birth. Whatever you do, don't share that thought with a pregnant woman or she may hurt you. The good news is there may be a much easier and less painful way to pass a kidney stone and all it requires is a trip to Silverwood Theme Park in Idaho.

ABC7 is reporting that Michigan State researchers have learned that it is possible to pass kidney stones by riding roller coasters. Sign me up for this.

Scientists created 3D printed models and planted kidney stones of varying sizes. Then, the silicone kidneys went for a ride.

The results? Even the largest stones got dislodged after two or three rides.

This sounds too good to be true, but the word is that all that roller coaster motion combined with adrenaline is what makes the kidney stones decide it's time to depart.

That begs a more important question. Of all the Silverwood coasters, which do you think would be the most effective at kidney stone removal? Here are 4 that come to my mind. Feel free to add your own if you have a favorite not listed here.

My vote goes to Corkscrew, but I'm notorious for being wrong - a lot.
