Is there any reason *not* to go to Dorney Park and ride the roller coasters in an attempt to get my kidney stone to pass?

The actual study, where researchers took a model of a kidney on roller coasters and fed kidney stones through it:

News article about the study:

I could ask my urologist, but I bet he'll say "no" and I guess if I have to hear "no" I'd rather hear it from fedi.

De Gruyter Brill · Validation of a Functional Pyelocalyceal Renal Model for the Evaluation of Renal Calculi Passage While Riding a Roller CoasterContext: The identification and evaluation of activities capable of dislodging calyceal renal calculi require a patient surrogate or validated functional pyelocalyceal renal model. Objective: To evaluate roller coaster facilitation of calyceal renal calculi passage using a functional pyelocalyceal renal model. Methods: A previously described adult ureteroscopy and renoscopy simulator (Ideal Anatomic) was modified and remolded to function as a patient surrogate. Three renal calculi of different sizes from the patient who provided the original computed tomographic urograph on which the simulator was based were used. The renal calculi were suspended in urine in the model and taken for 20 rides on the Big Thunder Mountain Railroad roller coaster at Walt Disney World in Orlando, Florida. The roller coaster rides were analyzed using variables of renal calculi volume, calyceal location, model position on the roller coaster, and renal calculi passage. Results: Sixty renal calculi rides were analyzed. Independent of renal calculi volume and calyceal location, front seating on the roller coaster resulted in a passage rate of 4 of 24. Independent of renal calculi volume and calyceal location, rear seating on the roller coaster resulted in a passage rate of 23 of 36. Independent of renal calculi volume in rear seating, calyceal location differed in passage rates, with an upper calyceal calculi passage rate of 100%; a middle calyceal passage rate of 55.6%; and a lower calyceal passage rate of 40.0%. Conclusion: The functional pyelocalyceal renal model serves as a functional patient surrogate to evaluate activities that facilitate calyceal renal calculi passage. The rear seating position on the roller coaster led to the most renal calculi passages.

Tour of the nascent National Roller Coaster Museum in Texas:

youtube.com/watch?v=1uM2bE4IGGM

Lots of memories here--they've got pieces of most of the defunct coasters I've ridden and a couple of still-running ones. They claim to want to turn one of the Canobie Corkscrew's inversions into an entrance arch.

For what it's worth, the comments are full of people expressing skepticism that this place will ever really publicly open. But apparently they do hold periodic events at which you can tour the collection.

From 1994-2010, the the Duinrell amusement park in the Netherlands had an attraction called the Fly Over slide, which was the first and only waterslide entirely filled with water. For @Defector, Barry Petchesky writes about this nightmarish ride. We want to know: What do you think of rollercoasters and thrill rides?

Here's the shot everyone gets of Loch Ness Monster at Busch Gardens Williamsburg. When it opened it was briefly the tallest complete-circuit roller coaster in the world. Today it's dwarfed by other rides at the same park, but it's still the most photogenic, and it was clearly built to be seen from this spot. Unfortunately, the dispatches are no longer timed so that two trains can duel in the loops. #rollercoasters

The first drop and two interlocking loops of the roller coaster Loch Ness Monster. Bright yellow track with gray supports appears among tall trees over a reflecting body of water. The first drop plunges from right to left, and beneath it, a train is making the uppermost of two loops that perpendicularly pass through one another. At left, in blue, you can barely see part of one of the inversions of Griffon, a much taller dive coaster. The sky ride is also passing through the scene.

The iconic view of Wildcat's lift hill (and Phobia Phear Coaster and Down Time) looming above the entrance gate of Lake Compounce. The park had short hours today, with a bunch of school trips visiting, and Boulder Dash wasn't running, but Wildcat was. Since the track work over the past couple of seasons, it's running better than it has in decades and we were sure to get in a ride.

The highlight, though, was that their excellent raft ride Thunder Rapids (which can be frustratingly hard to find operating) *was* running today and we got in three rides on it. I think this was also the first time I actually went in the lake, at the small beach there.

The front entrance gate of Lake Compounce amusement park, a festive yellow-and-blue structure with turnstiles beneath. Behind it and some other brightly colored buildings rises the white-painted lift hill of a wooden roller coaster; behind that, an orange steel coaster and a tall drop tower; behind those, a forested mountainside.

going to write a proper introduction post!

hello, my name is neo. i'm a transmasc in my 20's. generally speaking i like machines that move people, amusement rides, shooter games, and various sci fi and sci fi-adjacent media. i'm in between jobs right now, but my background spans aerospace engineering, acting, teaching, and operating amusement rides.

i occasionally draw and shoot 35mm film! (even less often, i write mediocre fanfiction.)

i'm on the fence about talking about my mental issues on new social media pages but you might find me mentioning them down the line.

i'll put my interests in the tags. (hopefully that's considered helpful here, like mastodon, and not spammy like it is on some sites.) happy to be here!

The coaster wheel project is complete (for now)!

The wheel is out of the vinegar and got another good scrub with soap and water before getting dried and oiled a little bit.

Any rust that's visible is flash rust- which formed after treatment while it was still a little wet with water. Pretty hard to avoid any rust.

I'm super, duper, incredibly happy with how it turned out. Even the rust on the grease port has been cleared. Most of the iron oxide (the black dust) was removed in the vinegar soak and with a soapy scrub.

The very last thing I plan to do is to give it a little bit of a polish. But here it is, all cleaned up!

I do wish the smooth coating was more intact but this is the wheel I have to work with unless someone at Holiday World reads this and wants to send me a new one! ;)

If I ever get around to trying to polish this thing up I will definitely share pics of it. Until then, that's it for this restoration. It was a lot of fun and I'm super happy with it. Thanks for coming along with me!I do wish the smooth coating was more intact but this is the wheel I have to work with unless someone at Holiday World reads this and wants to send me a new one! ;)

A photo of my newly restored roller coaster upstop wheel. The hweel is made of iron and is about 8 inches wide. It has a wide hole in the middle where it slips on to the coaster train's axel. There's a tiny bit of flash rust on the item, but largely it's grey and black.

Here's the wheel this morning after an overnight in the tank. It got a scrub with the kitchen brush, dried up, and oiled a little. It's still going to go back in the tank later, but damn, I'm happy with the progress.

You can see some of the smooth coating (teflon?) on the road surface of the wheel is still intact. This is why I didn't want to sandblast or brush it. I wanted to preserve as much of that as possible.

An iron wheel about 8 inches wide sitting on my desk. It has some spots of rust on it, but largely looks like it's been cleaned quite a bit. There's maybe 15% rust coverage as opposed to the 100% and then some it had before I started cleaning.

@ericg The one of these I've ridden is Big Bad Wolf, and yes. That wasn't my first roller coaster but it was the one that convinced me that I could love roller coasters.

But I think that, in hindsight, I also miss the one I rode before that, which was Mr. Twister at the original Elitch Gardens. At the time, it was too much for me. But man.

And then... there's Drachen Fire. Kind of a love-hate taste to the memories there.
