As someone who studied engineering, works in theme park design, and is just an all around coaster enthusiast, can confirm this video is on point. Even using the the correct geometry based terminology of clothoid loops to describe the “teardrop” loop., made famous by the manufacturer Arrow Dynamics (who also helped make the Matterhorn). Fun thing to notice, Arrow built a number of geometry based coasters (as opposed to force-based) with the clothoid loop. But for a long time only used one size for the loops design. So the bigger the first drop, the higher the same sized loop had to be off the ground. Examples, Great American Scream Machine, or the still operating Viper at Six Flags Magic Mountain.
@@jakethecake6952 I studied civil and structural engineering, though mechanical may be more preferred if wanting to deal with the physics and movement of the coaster. Structural obviously deals more with the non-moving parts of a coaster like the supports

I live half an hour from HersheyPark and visit frequently. When I was younger, I hated coasters, but SooperDooperLooper was one of the first ones I tried to get over my fear and it barely even realized I was going around the loop! Thanks Vox for explaining the technology behind smoothing the g force and the mechanisms in place to make these things awesome (yes I do love coasters now)!
I also live about an hour from Hershey! I also live close to Knoebels! If you live in PA it’s definitely worth a try. They have some of the best wooden roller coasters i’ve ever been on. So much fun.
Upstate NY checking in. Hersheypark is my families favorite park for many reasons. My favorite 2 coasters there are Great Bear and Lightning Racer. Our son and I enjoy MOST of the coasters there with his favorite being Skyrush and Lightning Racer. Our least favorite though is Wildcat.
I would like to thank Chris Sawyer for his RollerCoaster Tycoon series for introducing the concepts of rollercoasters (and theme parks) to millions of children like me, who are either unable or less fortunate to go to one. But I'll always enjoy to go on one in any shape or size...
@@chris1z142 They didn't mention cost in their comment. There's plenty of reasons why a child may have never been to one. I know for my family, the issue was that my parents worked a lot of hours just to barely scrape by, and were simply too exhausted to make a multi-hour journey to one on one of their rare days off. Though on the point of cost, I borrowed the game from a friend, as I'm sure many did at that time (and knockoff copies were definitely widely available).
I'd also like to thank him for introducing me to the concept of g-forces and how that can make or break a ride. Didn't fully understand what caused ultra-extreme g's tho until more recently, thanks to Marcel Vos's vids.
Vox over here making a video about rollercoaster engineering and they did their research to the point where enthusiasts won't be able to rip this video apart. I'm impressed. Well done! I loved the quick flash to Olympia Looping in that transition near the end there.
This is also exactly why the radius of turns in roads are variable, just such that the steering input is gradual rather than you having to flick it in. This is especially evident with on-off ramps of highways.
@@maxhagenauer24 They curve them to get around things like mountains or hills we don't really notice much while driving. Probably made their job much easier when putting them in. If you're in the midwest that seems fairly straight to me. In the appalachians very curvy because of all the hills and mountains.
@@maxhagenauer24 I have no idea what you're asking about, but if you're asking why roads are BANKED or slanted in other words, that's for rain water to flow off of them more quickly instead of flowing along the length of the road, making it slippery especially with icing in winter.
For a similar reason train tracks and street curves (like offramps) aren't perfect circle sections like you may find on a model railway either. If they were, turns would be really violent or require you to turn your wheel in an instant.
It isn't that the circular section is "violent," but that it starts and ends too smoothly, and drivers' reaction delay leads them to go past the point where they should start turning noticeably. Making an unnaturally abrupt start to the curve (which is often how the curve is altered) forces the driver to start the curve sooner. With roads, which are much wider than most of the vehicles traveling on them, this is also an adjustment to the better drivers who will turn sooner on their own and run on the shoulder if you don't give them more space on the inside of the curve. With roller coasters it's different because there can be no deviations.
Partly similar but in a rollercoaster the speed drops predictably as the car goes up then increases as it goes down which is why the bend radius is much smaller at the top. At 5:13 it's clear the G force is nearly constant.
Been putting off watching this video because it didn't seem interesting from the title and thumbnail. I'm glad I was proven wrong. Absolutely amazing story telling and the amount of work required to tell it is inspiring and the quality is AMAZING! Here's hoping this becomes a new genre of investigative journalism throughout RUclips. Please do more of this!
This explains why athletes have so much trouble when they try to ride full pipes or loops. Every loop I've ever seen built for skateboard, bike, motorcycle, etc were all perfect circles.
You forgot to mention that the engineer who invented the modern looping coaster is Werner Stengel from Munich. He invented also many other things in Rollercoaster design. Revolution in six flags Magic mountain was built by Schwarzkopf and designed by Stengel. Stengel also designed Top Thrill Dragster, Millennium Force and Kingda La (and many hundreds more).
I went on my first looping coaster in 1978 at Astroworld in Houston. The ride was a shuttle-loop coaster named Greased Lightnin’. It was unbelievably thrilling at the time. A few years later I went on the Judge Roy Scream at Six Flags Over Texas, which was a full coaster with two loops! It seemed like no roller coaster could ever get more exciting than that. Now, that sort of ride is very tame compared to most other coasters.
Nah, we jumped a whole part of history once the tubular steel was mentioned: who thought to go from a one car structure to multicar? And how much testing was involved? I don't like coasters at all but this was an interesting video. Thank you!
I think the 4.9 is like the average all around. You only have those high spikes of 10 G’s for not even half a second. So 4.9 Gs is around the average a rider will feel during the loop in total. I don’t know if I make sense. But I hope I help
One time I was seated next to a blind middle schooler on Magic Mountain's Revolution. A bunch of people started screaming like as soon as the ride started moving and this 13ish year old just yelled " *WHY ARE YOU ALL SCREAMING??? I'M BLIND AND I'M NOT EVEN SCARED!!* " Classic pubescent snark 😂
Sooperdooperlooper's loop is still quite a bit more circular than the loops on newer coasters. You can definitely feel more force in the loop than you would expect given the fairly paltry 45 mph speed. It's actually pretty surprising since the first drop is so gentle (as is the rest of the ride). It is cool though having the track pass through the interior of the loop. More coasters should do this, especially since coaster loops have gotten so much bigger with a lot more space inside. Maybe even put it towards the end of the layout after the mid-course brake run, so there's a chance your train passes through the loop as the next one is traversing the loop.
Amazing that a news company can get you interested in almost anything

I love the "Olympia Looping" at 5:51, it seems to be the biggest mobile multiple loop roller coaster in the world. I try to ride it every time it is in town.
@@prestonksp3432 Schwarzkopf coasters like the Olympia Looping are pretty old, and as far as I know it wasn't that big of a standard to make the teardrop shaped loops back then. It shows when you're riding it, the loops are pretty intesnse!
@@aequus2196 No, Schwarzkopf together with Werner Stengel introduced the clothoid loop back into roller coaster making, they are the base of the reemergence of the loop. The first loop on Olympia Looping is a deviation of the clothoid form, but only because they knew how to do it. It rides wonderful. With the "Thriller" they even managed to build two loops behind each other, a feat Arrow could've never managed with their cookie cutter elements.
i live super close to hershey and i’m basically there every week or two in the summer and it’s super fun, the sooperdooperlooper was my first ever coaster and it’s what go me into coasters really. it’s a really interesting and fun ride even though it seems kinda lame to today’s standards.
Corkscrew at cedar point was technically the first tear drop/Clothoid shaped vertical loop. Revolution was the first to do a successful vertical loop with more of a circular shape. The 2 we're by different manufactured and different styles.
Yup. The Corkscrew was built by the American builder "Arrow Dynamics" who also made the Matterhorn bobsleds, but the Great American Revolution, as well as the Sooperdooperlooper were made by the German Rollercoaster builder Anton Schwarzkopf, who by this point were Arrow's biggest competitor for large scale steel rollercoasters.
Spin a ball on a string in your hand and just sense the forces you feel in your hand. Then try to make a Smith circular spin straight after starting and try make a Smith sensible exit mimicking the shapes of these loops. You will see the circular spin exerts more pressure on you and is much more tricky to complete in a perfect circle as it naturally wants to break up the shape. It also shows that a less circular path exerts less pressure on the Shape as a whole meaning that structural integrity is safer not only due to material but the trajectory it's self
Are you serious??? 😑 few days ago I searched up the whole internet for this question cause I needed it for my Physics class. If only u had made this video before 😓
I'm a massive roller coaster fan. Thankfully I had the chance to go to Six Flags a few times and Sea World once growing up. I had no idea that the physics were like this. Very interesting. Great video. Thank you.
Tom Scott, on Citation Needed: “[the flip flap railway] was the first loop the loop in America” Matt Parker: “and they got the shape wrong? Were they lured in by the easy appeal of a nice circle?”
holy cow, I rode the Revolution at Magic Mountain the year it debuted. I had no idea it was so special in the history of coasters! I was so scared to go on but after my first ride I was addicted to coasters! Sadly, back problems make me hesitant to test out the newest iterations.
first time I rode Revolution at Magic Mountain was back in the 80's when it was just a lap bar and no headrest. I remember my head going down by my legs in the loop.
Did the first one actually subject the passengers to 14 g's? Or was that just AN example of a circular loop and not a model of one that was actually put into practice? Because 14 g's is a lot. The hypothetical euthanasia coaster would only be about 10 g's but it would keep it up for a minute. Never mind the acceleration function being discontinuous, just it being 14 is a problem.
It was also troubling that it was suggested that circular coaster riders were subject to an instantaneous jump from one to fourteen g’s. That is not possible. It could be very dramatic change - but not instant.
@@englishatheart Actually if you wanna be totally pedantic/correct about it, the correct way to spell out a reference to the letter G is to write "gee" or "gees." Not makin this up, Google it!
There's something off about those graphs. No way it is 14 g. The graph shows the modern coaster at 9 g, which also wrong. Halve those numbers and you're on the money. A circle would be more like 7 g and a modern loop 4.5 g.
What they said about 6 gs making you pass out, there's a coaster at kings dominion in VA called the intimidator or something like that it's a Dale Earnhardt themed coaster. The first drop is like 300ft straight down then you hit a 80° banked turn. EVERY single time I've rode it I black out on that first turn. So I'm guessing it's right at 6gs
Intimidator 305 goes to about 4.5 gs (which is still a lot for a rollercoaster), but people still black out because it's a sustained force throughout that whole helix turn. Very few rollercoasters nowadays reach 6 gs.
@@OffByHearttt Yep, the second half of the turn leading into the airtime hill was raised off the ground so you would go through it slower and experience less gs.
I once convinced my sister that the sooper dooper looper did not have a loop in it. She still hasn’t forgiven me, and the rest of our family hasn’t let her hear the end of it 😂

Yeah no I couldn't disagree more, I have always been so interested in the subject of G Forces on roller coasters and vehicles but I feel like this was one of the worse videos explaining it tbh.
The same rules apply to roads! You'll never find a circular turn, for example, on a motorway or highspeed road, the change in gradient is just impossible to steer into. Instead, curves are made up of a series of parabolas which feel circular, but are not. If turns were circular, you would have to turn your steering wheel from 12 o'clock to the angle of the turn in an instant. But we all know that's not how you take a motorway curve, you slowly adjust your steering as you go round the bend, with your wheel turned the furthest at the apex, and then you slowly return it to the 12 o'clock position as the road straightens out.
Love ACE! I ride a coaster called Shockwave all the time, and true to its name it’s incredibly forceful. This thing opened in 1978 and pulls a whopping 5.9G’s during its double loop sequence, making it the second most forceful in the world. Incredible ride. Always fascinating hearing how these things are engineered
Very interesting video, I never thought about it but it's cool how they perfected it. Also, why are people disliking this video (Browser plugin sees all)? It's science, that's how it is.
I love vox so much like they have a very wide scope of contents to share. A+ for their research based ideas too. Its like there are things im so curious but never popped a question yet but vox is here to give an absolute great answer haha
Grew up on Revolution! They kinda make a big deal about it at the park, but it’s super cool to know it’s the first of the hollow steel tracks and modern loops!
How are you talking about loopings without mentioning Werner Stengel?! That man essentially revolutionized the entire rollercoaster industry when he designed Revolution at SFMM! He deserves more recognition. Edit: Ron Toomer also deserves a mention for creating the first modern inversions with his Arrow Corkscrew coasters
I rode it many times before joining the Navy. The Laser Loop was powered by an old steam catapult from the USS Lexington aircraft carrier, that oddly enough I got to ride in 1987 for a "CQ demo" out of Ft Lauderdale while in VA-37 stationed at NAS Cecil Field. GO BULLS !!..

I remember feeling very frustrated when I was a kid playing Roller Coaster Tycoon and not having perfectly round loops. Then I switch to playing NoLimits Coaster 2 and my dream of a circular loop was fulfilled lol
I wish the graph more accurately matched what you're saying... at 5:17 the G-Forces are still around 10 (which wasn't that big of an improvement from the 14 in the first-ever loop), but you said in your real-world example that the G-Forces maxed out around 4.9 (which is very impressive, but not demonstrated properly on the graph).
Proud to say that Hershey park is 2 hours away from me in NYC and I have ridden the Sooperdooperlooper every time I go to Hersey. That ride is so much fun and the loop is no joke 😂
Nice and interesting video! As a improvement point, please include some form of metric measurements, I found myself having to google feet to meters to get a size perspective
dfrocha1 - Simple estimated conversion of feet to meters: There are 39 inches in a meter, 12 inches in a foot and 3 feet to one yard. I.e., there are 3+ feet/1+ yards to a meter. So, 150 feet = 50 yards = 50 meters less 8% = ~46 meters (yards x 92% OR feet x 92% divided by 3). [To simplify further for head calculations: convert feet to yards (feet divided by 3), times 90% then add 2%.] Once you have done this a few times, you should find it quite quick to calculate a rough estimate. Being in the U.S., I use the reverse for rough estimates: 1.08 times meters = yards then times 3 for feet. Or use meter plus 3 inches per meter. This means 16 meters equals 16 yards + one foot per four meters = 17 yards and one foot. [To simplify further for head calculations: Use 1.10 times meters then subtract 2%.]
There is a small problem that yall forgot which is that the flip flap railway and loop de loop needed circular loops to complete the loop without passengers and cars falling off the track and crashing into the bottom of the loop because they didn't have upstop wheels.
You mean they needed enough speed and thus high g-forces to create enough centrifugal force. The loops would still have been better with the cochloid shape.
I don't actually know if they had upstop wheel back then but if not, you still get a little under 12 Gs on the top of the loop when you only need 1 G to keep it up so it doesn't fall.
Then there’s the enclosed water slide from Action Park that ended in a loop that was a perfect circle… and sent so many people to the hospital because of either whiplash, or bashing their head into some part of the inside. 🤦♂️
Yep, this is why when you're engineering something like that, you'd likely want to go with a shape that keeps acceleration to a tolerable level and adjusts the radius to make that work.
@@bornh8r it’s because no experts were really consulted lol. The owner of the park who was a wall st businessman and real estate developer drew it on a napkin and they built it. Action park is a fun rabbit hole if you ever feel like watching a video on it
Even action park only had it open for one season! It was about 10g. People were consistently hurt by it, so they added padding. Then people were cut by it. They investigated and they found previous riders had left teeth embedded in the padding.
@@chrono9503 What im saying is they never needed to get rid of circular loops, that's what made them fun and now they are forceless. All we have left are Schwarzdof Looper loops that are almost circular but aren't.
I live close to Hershey and also used to work there. The first time I went on it, my head went forward and was like that for the whole loop but then came back up haha! Just my advice, press your head back as you enter the loop. Fun though and you feel secure even though it’s not an over your shoulder seat
Sad that you didnt mentioned the genius behind the first looping; Werner Stengel, a german engineer, who developed the clothoid shape and also drawed the conctruction. He also developed even more systems like the heart-line role and other forms.
They must be missing out - it''s three great parts - the circular shape of the loop that makes it so unique and fun, then swinging back through the loop and then winding along the terrain along the hill and through the trees. It's a classic!
As an enthusiast, before watching this video. The simple reason as to why was that with a circular loop, the G-forces coming in to the loop were too high, and too little at the top. The design we have now evens out the G-forces throughout the element.
Yes, you could lower the g-forces, but then you're likely to have the car fall off the track at the top, or you can have the higher g-forces and risk injuring the passengers. Changing the shape was ultimately the best choice as the varying radius could help to cushion the impact of the acceleration and allow for the car to stay on the track at the top and the passengers to not be hanging from the seat belt.
@@SmallSpoonBrigade Ok you clearly don't know how coasters work, there are upstop wheels on the bottom of the track to keep the train on, during negative Gs, also the old coasters did not injure the passengers, the high Gs aren't really bad for the human body, its just that the general public didn't like the feeling of greying out and the intensity.
I've been on a loop that pushed my head down so hard that I felt like my neck was gonna snap. It seems not all engineers have learned since the late 1800s.
2:26 I should point out a few things from the graphic. 1. The Space Shuttle had a G limit of 3 because the shuttle stack was very fragile, and it would break apart if the forces increased beyond 3G, however other rockets pull more, like the 2nd manned space program, Gemini, which used the Titan II ICBM as a booster. Those astronauts pulled *7-8 G’s* 2. The F-16 is capable of pulling +9.5 Gs, and pilots train for that. Other Fighters can do that, too, such as the F-22 Raptor. 3. Ejecting from a fighter jet will give you a brief boost of +12-14 Gs.
They tried really hard to get impressive looking stats below that 6G line, I think. They took an F-16 roll, which I actually can't find any info on. I imagine it'd mostly be lateral and some negative if you're going full on since the cockpit sits somewhat above the roll axis AFAIK. Humans are quite good at withstanding sudden spikes in G force (depending on the circumstances). Humans tend to have trouble with sustained G's.
@@carultch Yes! I had his class in 2017, so post-pilot program I guess. They interviewed me about the system and used that clip in some early promos for Learning Glass. I even got to go to see him get an award for it and my interview was in the presentation. I'm a big Matt Anderson fan and the system was a fantastic idea!
@@anthonyfaye3344 What was it like seeing the two mirror images of him while watching his lectures? Did you feel inclined to watch the real version of him, where the writing is backwards from your point of view, or did you instinctively look to the screen to see his writing reversed so it is legible? I feel like that's the drawback is that the live audience would be more inclined to watch him in the flesh where his writing is backwards, than to watch the live video where it looks the way it is intended. The best part is when he has to go against his instincts and use his left hand for the right hand rule, so that the figure in the video uses his right hand.
That's awesome that the mechanical engineering "consultant" became so inspired by the question to veer off and do a bunch of scientific analysis on his own lol of course, I suppose we all found ourselves with slightly more time, during the once-in-a-century worldwide Pandemic lockdown situation than usual. 👍 It's still fairly impressive, answering the question with science.
And in 1975, we went on "The world's first spiral roller coaster" at Knott's Berry Farm. It was supposed to be like a nineteen-twenties Coney Island twister.
The values of G force mentioned in the video and on graphs are all over the place. 2:52 the values change from ~8 to 14 at the top of the graph 5:11 clothoid has around 10G at the peak on the graph, but video 5:23 mentions 4,9G. I know it's for that one specific real life loop, but shouldn't it be at least somewhere close? Oh wait, if you actually used the graph provided by george it would be close! But instead you used a graph that *you claim* was sourced from george 5:31 On your graph it was 8G at the top of the loop (middle of graph), not 9G Why
yeah its weird but i feel like roller coasters in general have become more safer and more comfortable while also feeling more intense and scarier at the same time. heck i would even say the fear and intense factor are getting less and less lol.
Thank you Vox! This video makes so much sense! Does anyone remember 'SuperLoops'? It was a carnival ride that was literally just and enclosed perfect circle, going round and round, stopping at the top. 🤢
It blew my mind when I first knew that there were loops in the Victorian era, even before the mass began to use electricity ... ! people on loopings with top hats and corsets 🤣.

For a similar reason train tracks and street curves (like offramps) aren't perfect circle sections like you may find on a model railway either. If they were, turns would be really violent or require you to turn your wheel in an instant.
Exactly, instead of semicircles they use segments of a spiral arc to make the turns smoother
It isn't that the circular section is "violent," but that it starts and ends too smoothly, and drivers' reaction delay leads them to go past the point where they should start turning noticeably. Making an unnaturally abrupt start to the curve (which is often how the curve is altered) forces the driver to start the curve sooner. With roads, which are much wider than most of the vehicles traveling on them, this is also an adjustment to the better drivers who will turn sooner on their own and run on the shoulder if you don't give them more space on the inside of the curve. With roller coasters it's different because there can be no deviations.
Yea transition tracks increase the centripetal force gradually and not immediately
Partly similar but in a rollercoaster the speed drops predictably as the car goes up then increases as it goes down which is why the bend radius is much smaller at the top. At 5:13 it's clear the G force is nearly constant.
SCIENCE!

This explains why athletes have so much trouble when they try to ride full pipes or loops. Every loop I've ever seen built for skateboard, bike, motorcycle, etc were all perfect circles.

You forgot to mention that the engineer who invented the modern looping coaster is Werner Stengel from Munich. He invented also many other things in Rollercoaster design. Revolution in six flags Magic mountain was built by Schwarzkopf and designed by Stengel. Stengel also designed Top Thrill Dragster, Millennium Force and Kingda La (and many hundreds more).
you mean Kingda Ka
Of course Kingda Ka. Just a typo.
As someone who has Ph. D. in Mechanical Engineering, I enjoyed, learned, and also nod throughout the entire video. I loved it, thank you. Nice work!
I went on my first looping coaster in 1978 at Astroworld in Houston. The ride was a shuttle-loop coaster named Greased Lightnin’. It was unbelievably thrilling at the time. A few years later I went on the Judge Roy Scream at Six Flags Over Texas, which was a full coaster with two loops! It seemed like no roller coaster could ever get more exciting than that. Now, that sort of ride is very tame compared to most other coasters.
shoutouts to judge roy scream, the rattler, and the texas giant!
Nah, we jumped a whole part of history once the tubular steel was mentioned: who thought to go from a one car structure to multicar? And how much testing was involved? I don't like coasters at all but this was an interesting video. Thank you!
That jump was pretty made with the first modern loopers like Corkscrew at Knott's and Revolution at Magic Mountain.
They made the loop much bigger to reduce the G force and that also allowed them to fit bigger trains
Multicar train already exist before bottom wheel even exist for rollercoaster.
Multiple cars just kinda happened. Arrow dynamics ahd Schwarzkopf did it around the same time. Except arrow was wildly more popular.
Multiple cars in a train had been a thing for a long time, earlier ones even featuring a brakeman who had to manually brake the train
Your graph at 5:12 shows the Clothoid Loop peaking at above 10G, but then you claimed that it peaks at 4.9G - are all your graphs inaccurate?
I think the 4.9 is like the average all around. You only have those high spikes of 10 G’s for not even half a second. So 4.9 Gs is around the average a rider will feel during the loop in total. I don’t know if I make sense. But I hope I help
@@eatyourvegetables1449 no, 10 g is dangerous even for less than half a second. i think that 4.9 g is the max force, so the graph may be inaccurate

One time I was seated next to a blind middle schooler on Magic Mountain's Revolution. A bunch of people started screaming like as soon as the ride started moving and this 13ish year old just yelled " *WHY ARE YOU ALL SCREAMING??? I'M BLIND AND I'M NOT EVEN SCARED!!* "
Classic pubescent snark 😂
Sooperdooperlooper's loop is still quite a bit more circular than the loops on newer coasters. You can definitely feel more force in the loop than you would expect given the fairly paltry 45 mph speed. It's actually pretty surprising since the first drop is so gentle (as is the rest of the ride). It is cool though having the track pass through the interior of the loop. More coasters should do this, especially since coaster loops have gotten so much bigger with a lot more space inside. Maybe even put it towards the end of the layout after the mid-course brake run, so there's a chance your train passes through the loop as the next one is traversing the loop.
there are still other loop coasters right? I was watching this and I was so confused because I swear there are tons of loop coasters!!
Amazing that a news company can get you interested in almost anything
I love the "Olympia Looping" at 5:51, it seems to be the biggest mobile multiple loop roller coaster in the world.
I try to ride it every time it is in town.
Oh yeah absolutely. Olympia is always such a fun ride
The photo of Olympia looks very circular, is that just camera angle?
@@prestonksp3432 Schwarzkopf coasters like the Olympia Looping are pretty old, and as far as I know it wasn't that big of a standard to make the teardrop shaped loops back then. It shows when you're riding it, the loops are pretty intesnse!
@@aequus2196 No, Schwarzkopf together with Werner Stengel introduced the clothoid loop back into roller coaster making, they are the base of the reemergence of the loop. The first loop on Olympia Looping is a deviation of the clothoid form, but only because they knew how to do it. It rides wonderful.
With the "Thriller" they even managed to build two loops behind each other, a feat Arrow could've never managed with their cookie cutter elements.
“Superdooperlooper”
Best name ever for a roller coaster
I had not even noticed the non-circle shape before watching this video. This explains everything in a good way!
i live super close to hershey and i’m basically there every week or two in the summer and it’s super fun, the sooperdooperlooper was my first ever coaster and it’s what go me into coasters really. it’s a really interesting and fun ride even though it seems kinda lame to today’s standards.
I live close to the grocery store I bought bread butter and cheese. Then I made and ate a grilled cheese sandwich.
Corkscrew at cedar point was technically the first tear drop/Clothoid shaped vertical loop. Revolution was the first to do a successful vertical loop with more of a circular shape. The 2 we're by different manufactured and different styles.
Yup. The Corkscrew was built by the American builder "Arrow Dynamics" who also made the Matterhorn bobsleds, but the Great American Revolution, as well as the Sooperdooperlooper were made by the German Rollercoaster builder Anton Schwarzkopf, who by this point were Arrow's biggest competitor for large scale steel rollercoasters.
Since revolution opened a week before I'm sure that's why it's gets the credit that's how it goes sometimes
Tysm I was always uncomfortable about how rollercoasters aren’t round . I thought it would look gorgeous round.

Why does this comment have no replies
also hi 5mmm
Spin a ball on a string in your hand and just sense the forces you feel in your hand.
Then try to make a Smith circular spin straight after starting and try make a Smith sensible exit mimicking the shapes of these loops.
You will see the circular spin exerts more pressure on you and is much more tricky to complete in a perfect circle as it naturally wants to break up the shape. It also shows that a less circular path exerts less pressure on the Shape as a whole meaning that structural integrity is safer not only due to material but the trajectory it's self
First step: actually learn how to spin a ball on a string in your hand
Are you serious??? 😑 few days ago I searched up the whole internet for this question cause I needed it for my Physics class. If only u had made this video before 😓

holy cow, I rode the Revolution at Magic Mountain the year it debuted. I had no idea it was so special in the history of coasters! I was so scared to go on but after my first ride I was addicted to coasters! Sadly, back problems make me hesitant to test out the newest iterations.
The amount of research that went into this is so awesome
I never thought there eould be an expert on roaler coasters, turns out there is in fact an expert for literally everything.
first time I rode Revolution at Magic Mountain was back in the 80's when it was just a lap bar and no headrest. I remember my head going down by my legs in the loop.
Did the first one actually subject the passengers to 14 g's? Or was that just AN example of a circular loop and not a model of one that was actually put into practice? Because 14 g's is a lot. The hypothetical euthanasia coaster would only be about 10 g's but it would keep it up for a minute. Never mind the acceleration function being discontinuous, just it being 14 is a problem.
It was also troubling that it was suggested that circular coaster riders were subject to an instantaneous jump from one to fourteen g’s.
That is not possible. It could be very dramatic change - but not instant.
Man, seeing people use apostrophes to make plurals (it should either be Gs or "G"s) makes my eye twitch.
@@englishatheart Actually if you wanna be totally pedantic/correct about it, the correct way to spell out a reference to the letter G is to write "gee" or "gees." Not makin this up, Google it!
@@balthazothrenier9048 thanks, I hate it LOL
There's something off about those graphs. No way it is 14 g. The graph shows the modern coaster at 9 g, which also wrong. Halve those numbers and you're on the money. A circle would be more like 7 g and a modern loop 4.5 g.
I first heard about the Flip Flap Railway on "Citation Needed." While that was fascinating and hilarious, this is much clearer.
To be fair, the mashmellow bearings were an excellent inclusion.

@@taylorboulton177 IKR
Fantastic job, Vox team!
Animation, story, edit, and sound were all on point :)
What they said about 6 gs making you pass out, there's a coaster at kings dominion in VA called the intimidator or something like that it's a Dale Earnhardt themed coaster. The first drop is like 300ft straight down then you hit a 80° banked turn. EVERY single time I've rode it I black out on that first turn. So I'm guessing it's right at 6gs
Intimidator 305 goes to about 4.5 gs (which is still a lot for a rollercoaster), but people still black out because it's a sustained force throughout that whole helix turn. Very few rollercoasters nowadays reach 6 gs.
I believe they had to re-profile intimidator 305 after it opened because the initial layout was too intense
@@OffByHearttt Yep, the second half of the turn leading into the airtime hill was raised off the ground so you would go through it slower and experience less gs.
@@fyre5287 Typical Intamin as usual
Shockwave at Six Flags Over Texas actually pulls more Gs, 5.9 I believe. I305 pulls around 4.5.

Yeah no I couldn't disagree more, I have always been so interested in the subject of G Forces on roller coasters and vehicles but I feel like this was one of the worse videos explaining it tbh.
The same rules apply to roads! You'll never find a circular turn, for example, on a motorway or highspeed road, the change in gradient is just impossible to steer into. Instead, curves are made up of a series of parabolas which feel circular, but are not.
If turns were circular, you would have to turn your steering wheel from 12 o'clock to the angle of the turn in an instant. But we all know that's not how you take a motorway curve, you slowly adjust your steering as you go round the bend, with your wheel turned the furthest at the apex, and then you slowly return it to the 12 o'clock position as the road straightens out.
Roundabouts for the win
Love ACE! I ride a coaster called Shockwave all the time, and true to its name it’s incredibly forceful. This thing opened in 1978 and pulls a whopping 5.9G’s during its double loop sequence, making it the second most forceful in the world. Incredible ride. Always fascinating hearing how these things are engineered
Very interesting video, I never thought about it but it's cool how they perfected it.
Also, why are people disliking this video (Browser plugin sees all)? It's science, that's how it is.

How are you talking about loopings without mentioning Werner Stengel?! That man essentially revolutionized the entire rollercoaster industry when he designed Revolution at SFMM! He deserves more recognition.
Edit: Ron Toomer also deserves a mention for creating the first modern inversions with his Arrow Corkscrew coasters
I loved riding the Laser Loop when it was in Kennywood Park here in Pittsburgh. The ride was sold and taken out in the mid early to mid 90’s.
I rode it many times before joining the Navy. The Laser Loop was powered by an old steam catapult from the USS Lexington aircraft carrier, that oddly enough I got to ride in 1987 for a "CQ demo" out of Ft Lauderdale while in VA-37 stationed at NAS Cecil Field. GO BULLS !!..

I wish the graph more accurately matched what you're saying... at 5:17 the G-Forces are still around 10 (which wasn't that big of an improvement from the 14 in the first-ever loop), but you said in your real-world example that the G-Forces maxed out around 4.9 (which is very impressive, but not demonstrated properly on the graph).
Make a better video then…
@@DelGTAGrndrs IKR!!
Proud to say that Hershey park is 2 hours away from me in NYC and I have ridden the Sooperdooperlooper every time I go to Hersey. That ride is so much fun and the loop is no joke 😂
Nice and interesting video!
As a improvement point, please include some form of metric measurements, I found myself having to google feet to meters to get a size perspective
dfrocha1 - Simple estimated conversion of feet to meters: There are 39 inches in a meter, 12 inches in a foot and 3 feet to one yard. I.e., there are 3+ feet/1+ yards to a meter. So, 150 feet = 50 yards = 50 meters less 8% = ~46 meters (yards x 92% OR feet x 92% divided by 3). [To simplify further for head calculations: convert feet to yards (feet divided by 3), times 90% then add 2%.] Once you have done this a few times, you should find it quite quick to calculate a rough estimate.
Being in the U.S., I use the reverse for rough estimates: 1.08 times meters = yards then times 3 for feet. Or use meter plus 3 inches per meter. This means 16 meters equals 16 yards + one foot per four meters = 17 yards and one foot. [To simplify further for head calculations: Use 1.10 times meters then subtract 2%.]
That´s the type of information I demand from internet. CLASSIC !!! love it
There is a small problem that yall forgot which is that the flip flap railway and loop de loop needed circular loops to complete the loop without passengers and cars falling off the track and crashing into the bottom of the loop because they didn't have upstop wheels.
You mean they needed enough speed and thus high g-forces to create enough centrifugal force. The loops would still have been better with the cochloid shape.
@@Robbedem Exactly but they didnt think clothoid loops because in the 1800s to early 1900s safety was the second priorty
I don't actually know if they had upstop wheel back then but if not, you still get a little under 12 Gs on the top of the loop when you only need 1 G to keep it up so it doesn't fall.
Then there’s the enclosed water slide from Action Park that ended in a loop that was a perfect circle… and sent so many people to the hospital because of either whiplash, or bashing their head into some part of the inside. 🤦♂️
omg that's terrible.. u would think the experts at tasked with designing and building waterslides would know better
@@bornh8r Amusement park safety was not really a thing in the 80s
Yep, this is why when you're engineering something like that, you'd likely want to go with a shape that keeps acceleration to a tolerable level and adjusts the radius to make that work.
@@bornh8r it’s because no experts were really consulted lol. The owner of the park who was a wall st businessman and real estate developer drew it on a napkin and they built it. Action park is a fun rabbit hole if you ever feel like watching a video on it
Even action park only had it open for one season! It was about 10g. People were consistently hurt by it, so they added padding. Then people were cut by it. They investigated and they found previous riders had left teeth embedded in the padding.

Just my advice, press your head back as you enter the loop. Fun though and you feel secure even though it’s not an over your shoulder seat
this ties perfectly with my recent roller coaster tycoon obsession, thank you!
this ties in perfectly with my general roller coaster obsession lol.
Sad that you didnt mentioned the genius behind the first looping; Werner Stengel, a german engineer, who developed the clothoid shape and also drawed the conctruction. He also developed even more systems like the heart-line role and other forms.
Hershey is my home park. I love when riders get on the SooperDooperLooper and go that's it? Expecting more than one loop.
They must be missing out - it''s three great parts - the circular shape of the loop that makes it so unique and fun, then swinging back through the loop and then winding along the terrain along the hill and through the trees. It's a classic!
i love the SuperDooperLooper; Its the first coaster I ever rode and there is hardly ever a line
loved learning about the coaster enthusiasts!! how wonderful :)
As an enthusiast, before watching this video. The simple reason as to why was that with a circular loop, the G-forces coming in to the loop were too high, and too little at the top. The design we have now evens out the G-forces throughout the element.
Yes, you could lower the g-forces, but then you're likely to have the car fall off the track at the top, or you can have the higher g-forces and risk injuring the passengers. Changing the shape was ultimately the best choice as the varying radius could help to cushion the impact of the acceleration and allow for the car to stay on the track at the top and the passengers to not be hanging from the seat belt.
@@SmallSpoonBrigade Ok you clearly don't know how coasters work, there are upstop wheels on the bottom of the track to keep the train on, during negative Gs, also the old coasters did not injure the passengers, the high Gs aren't really bad for the human body, its just that the general public didn't like the feeling of greying out and the intensity.
I grew up riding the wooden coaster the Comet in Crystal Beach, brother to the one in Coney Island.
I have never been on one seemed scary but now I want to try it.
It’s amazing what you find in the middle of the night on RUclips 😅
Oh! I've heard of this one from Tech Diff with Matt Parker!
5:48 Gardaland, Blue Tornado! Love it
I've been on a loop that pushed my head down so hard that I felt like my neck was gonna snap. It seems not all engineers have learned since the late 1800s.
you still probably only felt around 5-6Gs, far safer then 14G which would probably actually injure u
2:26 I should point out a few things from the graphic.
1. The Space Shuttle had a G limit of 3 because the shuttle stack was very fragile, and it would break apart if the forces increased beyond 3G, however other rockets pull more, like the 2nd manned space program, Gemini, which used the Titan II ICBM as a booster. Those astronauts pulled *7-8 G’s*
2. The F-16 is capable of pulling +9.5 Gs, and pilots train for that. Other Fighters can do that, too, such as the F-22 Raptor.
3. Ejecting from a fighter jet will give you a brief boost of +12-14 Gs.
They tried really hard to get impressive looking stats below that 6G line, I think. They took an F-16 roll, which I actually can't find any info on. I imagine it'd mostly be lateral and some negative if you're going full on since the cockpit sits somewhat above the roll axis AFAIK.
Humans are quite good at withstanding sudden spikes in G force (depending on the circumstances). Humans tend to have trouble with sustained G's.
5:21 "How many Gs to hit" I hate my mind 🤣

I'm a big Matt Anderson fan and the system was a fantastic idea!
@@anthonyfaye3344 What was it like seeing the two mirror images of him while watching his lectures? Did you feel inclined to watch the real version of him, where the writing is backwards from your point of view, or did you instinctively look to the screen to see his writing reversed so it is legible?
I feel like that's the drawback is that the live audience would be more inclined to watch him in the flesh where his writing is backwards, than to watch the live video where it looks the way it is intended. The best part is when he has to go against his instincts and use his left hand for the right hand rule, so that the figure in the video uses his right hand.
Graph at 5:13 shows clothoid max g of about 10, but 5:24 shows clothoidmax g of 4.9? What am I misunderstanding?

Awesome. Didn't know I needed this. But I did and I'm glad.
Please when is the "explained series" going to continue, if it's going to continue. Thanks
The values of G force mentioned in the video and on graphs are all over the place.
2:52 the values change from ~8 to 14 at the top of the graph
5:11 clothoid has around 10G at the peak on the graph, but video 5:23 mentions 4,9G. I know it's for that one specific real life loop, but shouldn't it be at least somewhere close? Oh wait, if you actually used the graph provided by george it would be close! But instead you used a graph that *you claim* was sourced from george
5:31 On your graph it was 8G at the top of the loop (middle of graph), not 9G
Why
I guess graphics designers didn’t study graphs. Oh the irony…
The research and the presentation is excellent! Sustained quality of videos impresses me Vox!
So, on those first circular rollercoasters people were getting knocked out by G forces several times in one ride? 🥴 yikes
yeah its weird but i feel like roller coasters in general have become more safer and more comfortable while also feeling more intense and scarier at the same time. heck i would even say the fear and intense factor are getting less and less lol.
Thank you Vox! This video makes so much sense! Does anyone remember 'SuperLoops'? It was a carnival ride that was literally just and enclosed perfect circle, going round and round, stopping at the top. 🤢
