"Pray hear a tale of wizardry about the brave knight Gerwain." "Gerwain wielded as a weapon, a mysterious force." "A force which caused his enemies to fall before him, their heads to drop like apples from a tree." "Uh, you mean like a natural phenomenon by which all things with energy are bought towards each other?" "Must be, I suppose." "Gerwain had but one weakness in his body... another body to whom he was attracted." "How attracted?" "Attractive force is proportional to the product of their masses and inversely proportional to the square of the distance between them." "Last I heard, he was a couple of leagues away." "To sap his mystical force..." "No." "No!" " his enemies did kidnap his betrothed." "Gerwain rushed to her rescue... the force increasing with each turn and every acceleration." "But alas, it was a trap." " For a moment, his will seemed broken." "Then Gerwain drew upon all his powers..." "Oh, she died beautifully." "unleashing forces positive... negative, and lateral." "Gee, his force has increased." "Gee, that hurt." "Driven by revenge," "Gerwain entered the forbidden forest..." " but foul play was afoot." "Lightning bolt." "Light hits." "You're dead." "Shut up, Falcor." "You can't throw three lightning bolts in one round." " You're not high enough level." " Uh-huh." "Last weekend, I did a side quest and leveled up." "Liar!" "You're always cheating." "You always play like this." "I'm leaving." " You're always picking on the wizard." " Fine!" "Ride off into the sunset." "See if I care." "I'm already dead." "You don't play by any of the real rules." "Look." "She's taking a selfie." "This isn't even fair." "What did I just see?" "Did you not pay attention to any part of the narrative?" "You and your friends get together on the weekends and play Lord of the Rings?" "First of all, it's not just on the weekends." "And secondly, it's called LARPing, which stands for live action role-play." "You just got nerd-checked." "So, our topic is g-forces and how people experience and survive high Gs." "We're going down the rabbit hole... to find out who has the highest g-force of all." "Oh, that was definitely a lot of Gs right there." "In the mix, a human crash test dummy... race car drivers..." "Feels like the butterflies in my stomach are in my mouth." "and a g-force showdown between a roller coaster... and an Olympic bobsled." "Holy crap." "As usual, we'll score and rank our six contenders using three criteria." "Number of Gs, duration of Gs and extreme factor." "What exactly is with the knights?" "Behold, fair maiden." "Jousting?" "Jousting." "I figured if we're gonna be investigating g-force, why not go back in time and find the oldest example of extreme Gs?" "Jousting is at the top of the list." "Prepare to get medieval." "My lords and ladies, are you ready for a joust?" "Excuse me." "Sorry, sorry." "Sorry." "Are you ready for imperial mayhem?" "Um, excuse me, I've just" "Oh." "Uh, right over here." "Sorry." "Oh." "Oh, sorry." "And watch two grown men knock the snot out of each other?" "Knights." "Always with the anger issues." "Raise your voices!" "That is Charlie Andrews." "He's a ten-time world jousting champion and founder of the Knights of Mayhem." "This is one guy you don't wanna mess with." "Yeah!" "If there's anybody that can tell me about jousting, it's him." "Charge on!" "Wow." "This is violent." "And where there's violence... there's g-forces." "I'm here to figure out how to measure these medieval Gs... which means data." "Lots of data." "Charlie, that was amazing." "Good hard hitting, man." "What I need is some facts and figures about jousting." "Speaking of horsepower, how fast do they run?" "Between 15 miles an hour to 25 miles an hour." "How much does an average rider weigh?" "Between about 180 pounds to 250 pounds." "My suit runs about 130 pounds, 140." "This here is 10-foot-6-inches long." "Okay." "Solid hemlock, inch and a quarter." "If you notice the grids on here..." "Yeah." "Those grids are designed to catch the lance." "They get 100% of all the g-forces." "That's what we're looking for." "I'm measuring jousting Gs." "But there's no way I can capture raw data without a dry run." "To get definitive results in the heat of battle, we first need to test the sensors and software under fire in the lab." "Oh!" "This is exactly why, Grant," "I should've stayed in school." "Because then I could go back to the shop and use a simulator," "I wouldn't have to be the crash test dummy." "Where would be the fun in that?" "You're right." "Joust do it." "I'm back at the shop... and getting the team together to replicate... test out... and measure... some medieval Gs." "And in order to do that, we need to build a rail system." "There's gonna be two rails." "One rail is going to be our target." "A guy in a suit of armor." "The other rail is gonna be our lance." "We're going to pull back the bungees, just like a slingshot, and then fire them at each other." "Those are the two rails, and on the rails go two sleds." "Each sled has to replicate the speed of a galloping horse." "So, we need to top out between 20 and 30 miles per hour." "This is gonna be fantastic." "With the first sled in place and the bungees looped and tied, it's time for a quick systems check." "Okay, let me walk you through our whole setup here." "Starting off with the winch." "The winch is used to tension up the bungee cords." "It's gonna be removed once we click into the quick release." "The quick release allows us to be far away while this thing fires off." "Here's the sled." "It's gonna be un-weighted for this test because we just wanna see how the bungees are gonna perform." "Okay, pin is in." "This is the bungee cord." "It's the source of propulsion." "Pin's out." "And the tire is gonna stop the sled." "Radar standing by." "Radar is ready." "Here we go." "Three, two, one." "Yes, 26 miles an hour!" "Perfect." "Galloping horse speed, check." "It's almost like we know what we're doing." "Now for the horses, knight..." "Do not impale him on the pole." "and lances." "Let's joust." "And now for the most important part of this experiment, our accelerometer." "It's gonna help us determine how many Gs our knight experiences during his rapid deceleration." "I'm placing one directly behind the impact plate, but that's likely to get smashed." "So, I'm putting another away from the line of fire to see if it records the same data." "Yeah!" "I really don't wanna upset Charlie." "So, this had better work." "Here's where we're at." "We've built two tracks, each about 50 feet long, and two sleds." "Sled number one has 300 pounds of knight on it." "That's 180 pounds of guy plus 120 pounds of armor." "Okay, we're locked." "Sled number two has our lance." "That's an eight-foot-long wood dowel." "Plus, another 300 pounds to simulate the weight of the other knight." "Okay, now's the time for danger." "And if everything works out, both the lance and the knight will meet right in the middle of the impact zone, and we'll get g-force data." "Let's do this." "Okay, here we go." "This is head-to-head jousting simulator in three... two... one." "Yes!" "Success." "But before we download the data, we're gonna run multiple tests to see if those accelerometers can take a beating." "One." "Okay." "Let's see what we got." "Looks like my g-force meter survived, which means we're in business." "At the moment of impact, we got a peak of 2.8 Gs." "Here's the best part." "The data from the front accelerometer exactly matches the data from the rear accelerometer, which means we can put our sensor anywhere on the knight and get consistent data." "Aw, this is gonna be fun." "All right." "G-force science is complex." "So, let's remind ourselves how we're gonna score our g-force contenders." "Number 1, total number of Gs." "Number 2, duration the Gs are sustained." "And number 3, the extreme factor." "How the body feels the Gs, how they experience them." "Now, in case you were asleep in science class," "I did a little educational video for you." "Ooh..." "G-force stands for gravitational force." "You know, gravity." "A ride on a swing is a perfect example of g-force in motion." "At the top of the arc, I get to that weightless feeling of zero-g." "And as I go down on the swing, at the bottom of the arc," "I hit my maximum deceleration of 2 G." "Taking off in a commercial airplane, 1.2 to 1.4 Gs." "Bungee jumping, 2.8 to 3.5 Gs." "Pretty bad idea but..." "You ride your bike into a wall, that's 5 to 10 Gs." "Plopping down in a chair..." "Ten Gs, but just for an instant." "Hey, what's up?" "What'd the five fingers say to the face?" "What?" "Slap." "Hey!" "Tory just experienced hundreds of Gs." "But only for an instant." "Sustained over a long period of time, that would tear your body apart." "We should watch that again." "Class dismissed." "Time for my first g-force junkie contender." "My contender isn't a thing." "It's a guy." "Colonel John Paul Stapp." "This guy did everything but kill himself on his g-force day job." "LieutenantColonelJohnStapp is ready for the fastest ride on earth." "In 1947, he embarked on a top-secret biophysics experiment..." "One." "Fire." "to explore the outer limits of the human g-force endurance." "During World War II, it was thought the pilots could withstand a max of 18 Gs." "But Stapp, a medical doctor with the US Air Force, didn't buy those numbers." "He set out to prove that pilots could withstand higher Gs, and therefore needed much more protection." "To do that, he needed an extreme g-force machine." "Crewmen fasten Colonel Stapp in with a network of belts and straps." "A rocket sled called the Gee Whiz." "Before Stapp, the only guy cleared to ride on the Gee Whiz:" "Oscar 8, the world's first crash test dummy." "And this is why." "When the Gee Whiz hit the water brake," "Oscar hit massive Gs." "He sailed through the wooden windscreen, left his face behind, and came to rest 700 feet downrange." "Who'd want that job?" "Step up Stapp." "He knew that the only way to really find out what g-force did to the human body was to ditch Oscar and use a human guinea pig." "Five, four, three, two, one." "Fire." "During the summer of 1948, he completed a hair-raising 16 runs that peaked at 35 Gs on braking." "He almost doubled the previously accepted ceiling for survivable Gs." "Colonel Stapp learns he has just traveled 421 miles per hour." "WhenChuckYeagerbroke the speed of sound," "Stapp wanted to find out how to protect pilots during supersonic emergency ejections." "I know, crazy." "So, in December 1954, protected only by a helmet and a visor, he strapped in, inserted a rubber bite block equipped with an accelerometer and the countdown began." "Four, three, two, one, zero." "Stapp hit 632 miles per hour." "Two tons of wind pressure." "And when he hit those water tanks, he experienced an enormous negative acceleration." "He peaked at a fraction of a second at 46.2 Gs." "But it's the sustained Gs that are the most impressive." "For 1.1 seconds," "Stapp endured 25 Gs, thought to be the highest sustained Gs ever survived." "His eyeballs were filled with blood from burst capillaries." "It was like a scene from a horror movie." "They thought he'd gone blind, but after ten terrifying minutes, his vision returned." "And the legend went on to live a long, and presumably, slower-paced life." "Ah, those were the good old days." "By putting his body on the line, Stapp saved the lives of countless pilots." "And he taught us much of what we know about the power of Gs." "Those were seriously impressive numbers." "A peak of 46.2 Gs and 25 Gs sustained for 1.1 seconds." "And he's an officer." "He didn't have to do this." "He could put a low ranking guinea pig in that seat, but he didn't want anybody else in harm's way." "Not to mention the countless lives he saved by making cockpits safer and being an advocate for car seatbelts." "For my next g-force contender... a roller coaster." "And I have a bet with Tory that it'll beat a bobsled in a g-force showdown." "This is the West Edmonton Mall, the largest mall in North America." "It has over 800 shops and services." "Including this:" "Mindbender." "Built in 1985... the Mindbender still holds the record as the world's tallest triple-loop indoor roller coaster." "The first drop is ten stories high." "And it finishes with riders hitting freeway speeds." "I'm here to feel the Gs and measure them." "It's gonna be fun." "I wonder how Tory's doing." "I bet he's cold." "Forget the carnival rides." "For my contender, I want to experience firsthand the g-force thrill of an Olympic-level extreme sport." "I'm here at Utah Olympic Park." "And behind me, tucked into the Wasatch Mountains, is the bobsledding track that hosted the 2002 Winter Olympics." "And I get the privilege of going for a ride with the current US bobsledding team to see how many g-forces I can experience." "Rest assured, unlike Grant's contender, this is not a ride for the fainthearted." "The track is a terrifying prospect, 4300 feet long with a 340-foot drop." "Towards the end of the run, we'll be at maximum velocity." "And it's on turn number 12... where speed plus tight radius plus sharp change in direction equals peak g-force." "It's too late to bail out now." "Now, while Tory is preparing himself on the bobsled track," "I need to prepare myself here at Galaxyland." "And that preparation consists of setting up my g-force measuring vest." "Yeah." "Oh!" "Ah!" "Oh..." "Like any piece of precision measuring equipment... it needs to be calibrated." "Hello, fair people of Galaxyland." "I've come to collect your data." "And to do that, I need to subject it to a number of different environments and collect as much data as I can." "All of it." "Once I feel that the data that I'm getting is accurate, then and only then will I put it to the real test on the Mindbender." "So, now that I'm set up to record the peak G-force and duration of those Gs..." "Oh!" "I want some insider info on how a rollercoaster uses those forces." "Meet Walter." "I'm an amusement ride safety inspector." "Okay." "Cool." "What types of Gs might we experience on a standard rollercoaster?" "So, you have three basic g-force effects on a roller coaster." "You have the negative Gs, where you're lifted out of your seat." "Say you're going over the top of a hill..." "You experience a negative force when you're lifted up out of your seat." "Your stomach goes up." "Yeah." "Yeah, exactly." "You have positive Gs you would experience at the bottom of a valley." "That's gonna pull you down into your seat." "Make you feel like you're two or three or four times as heavy as you really are." "Your lateral Gs, as you're going around a turn, say to the left... you're being pushed to the right." "You're going around a turn to the right... your body's being pushed to the left." "Cool, all right." "Where am I gonna experience the most Gs?" "I would place my money on halfway up the third loop." "Why the third loop?" "Because third loop is smaller and the approach to it is gonna give you more speed and quicker change of direction in a smaller area." "I've got a bet going with Tory that my roller coaster is gonna produce more Gs than his Olympic bobsled." "What do you think?" "From what I understand, this pulls some significant g-forces, and it'll be a very fun experiment to play with your accelerometer and find out." "I'm looking at the gate and there's a sign that says:" ""Severe injury or death beyond this point."" "Is that, like, an inside joke?" "Is that, like, serious?" "Is that to fool people like me?" "It's a serious warning." "Yeah." "Dude, I can't wait." " We're good." "We'll be fine." " Okay." "Now, how fast are we gonna be going?" "Probably get about 80 miles an hour today." "Holy crap." "That's no joke." "Yeah, it's fun." "Wow." "And with great speed comes great Gs." "Those guys are hauling." "They're moving." "Like Grant, I'll be measuring the g-force with an accelerometer." "What's the duration of the Gs?" "Uh, I'd say most of them are only about two seconds." "What happens to your body when you hit those Gs?" "A lot of grunting, a lot of compression." "Go to the bathroom beforehand." "I don't know if anyone told you that." " No, they haven't." " You need to." "Wow, this thing is so sick." "I mean, it looks like a missile." "It's pretty crazy." "So, you're going to be sitting up front." "Yeah." "Where am I gonna be?" "You're sitting in the third spot." "Okay." "We thought about putting you at the brakes, but..." " Yeah, I wouldn't trust me either." " Yeah." "Itmightlookabreeze when you see these guys do it... but it takes skill and training to guide this missile." "I screwed that one up." "Yeah, you got to get your feet in faster than that." "Luckily I'm just hitching a ride, getting off easy on the training... and not driving." "Eye of the tiger." "In here we've got these rings and then you pull." "Right, go right, left, go left." "And so, I just pull back on these puppies." "Off the ground." "Yup." "There we go." "Let's get another one." "Boom." "So, it's small inputs." "It's little inputs." "Some places, like... corner 12 here, you actually have to put pretty big input." "Go." "Oh, my God." "Otherwise the sled will just skyrocket to the roof and..." "Yeah, I've seen that happen a few times." "That's not gonna happen." "You'll be fine." " What the hell?" " Yeah." "So, this is kind of like, you know, like, when you're a kid going down the hill on your little sled." "Yup." "But on steroids." "Yeah, essentially." "But not really on steroids." "No." " Compete clean." " No steroids." "No steroids involved in this run." "I'm taking it that "steroids" is a bad word around here." "Steroids is a hot topic these days." "Uh, should we all take a pee test?" "Yeah." "Right now?" "Cups please." "Cups." "Would you say there's a lot more going on, a lot more skill involved than jumping on a rollercoaster, going for a ride?" "Oh, yeah." "Grant." "Tory right now is probably freezing his nuts off." "I mean, like, literally freezing them off." "They're probably like little ball bearings." "This is it." "Time to see who has the biggest..." "G-force." "Is that okay?" "Before the boys go head-to-head..." "I'm putting the pedal to the metal here at the Cathedral of Speed to check out the g-force physics of some seriously fast cars." "The Indianapolis Motor Speedway." "One sick track." "They're gonna let me get in a race car just to see how many Gs I can pull." "We've got two cars primed and ready to go." "And engineer Will is standing by to capture all the data we'll need." "We have gyros, accelerometers, lasers for ride heights." "I'm fascinated." "You can live-track everything that's happening in the car." "Yes, we see about 70 sensors live." "We're gonna strap you into the backseat of our Indy car two-seater, but this thing isn't as fast as my race car." "We're gonna give you a taste of some of the Gs, the numbers, then I'm gonna hop in my race car and get real numbers." "I am excited and scared all at the same time." "An Indy car has a 2200 cc V6 engine with a power output of 700 horsepower." "Oh, my God." "Yup." "It's fast." "Indianapolis' turn one at top speed is the A spot..." "Yeah." "for g-force." "A long, tight turn where drivers undergo peak Gs for several seconds." "Oh, my God." "Yeah." "Whoa." "Intheturnone , you hit about 2.9 lateral Gs." "Andtherewasbutterflies in my stomach, and all of a sudden... we'd go around a turn, all the butterflies shot up into my throat and I would lose my breath until we got to the straightaway." "Faster!" "I mean, I definitely feel like I got some good G." "I think the butterflies in my stomach are in my mouth." "We did four hot laps... peaking at 2.9 Gs for four seconds." "That was amazing." "There you go." "Just do that 196 more times and that's the Indy 500." "Oh, my God." "Let's see what James can do flying solo." "While he gets up to speed... let's put my numbers into 4-wheeled context." "When it comes to horsepower, top fuel dragsters accelerate quicker than a jet fighter and a space shuttle." "These beasts can hit 332 miles per hour in 4.5 seconds." "Off the line, they measure 2.5 on the Richter scale." "They pull 6 Gs at the start line and when they pop the chute, they can pop their retinas." "No, really." "That happens." "But duration is key." "Dragsters only experience those peaks for a split second." "And that's where race car drivers are king." "Okay." "So, James, looks like you're going about... 214 miles an hour, and damn," "James, you got 3.6 Gs." "That's crazy." "James experiences more than three times his body weight for four seconds and racers can even stray into G-LOC territory." "In a 2001 practice session at Texas Motor Speedway, drivers experienced almost 6 Gs for 18 of the 22 seconds it took to complete a lap." "Some came close to blackout and the race was canceled." "But there's one thing that creates more Gs than tight turns." "Now, I know it's probably a little bit of a sensitive subject, but the biggest change in acceleration I could imagine out in the track would be if someone crashed because you're stopping quickly." "Yes." "So, at Indy for sure you're going about 230 miles per hour and if you hit the wall wrong, you stop quickly." "Sudden deceleration from high speeds equals enormous Gs." "Off the scale." "Like this crash by Kenny Brack in 2003." "It logged 214 Gs for a fraction of a second." "It was a miracle he survived." "However, we're looking at sustained Gs." "And Indy car drivers take the prize with over 5 Gs for four to five seconds." "Would I do this again?" "Yeah!" "Yes, I would so do this again." "Kari's race-car cornering might pull some impressive Gs... but for my next contender, the sky's the limit." "Yup, I'm thinking jet pilots could take the top spot of most g-force exposure." "In fact, it was during the aerial dogfights of World War I... that g-forces were first identified." "In the heat of the battle, pilots were pulling more and more extreme maneuvers and passing out, or fainting in air as it was known." "Sudden changes in directions, extended tight turns and extreme climbs pulls the blood from the head to the lower extremities, causing you to pass out or G-LOC." "G-force-induced loss of consciousness." "It happened to me once, and it sucks." "It's understandable that people think the biggest acceleration someone can experience is during liftoff of a space mission." "But rockets are designed to keep the acceleration low to limit the Gs sustained so astronauts can remain awake and alert." "So..." "It's not the size of the engines, or straight-line thrust that matters." "It's the moves." "That means fighter pilots and aerobatic performers experience the greatest sustained g-forces." "They can't afford to lose consciousness at the controls of a multi-million-dollar aircraft." "So, they train in a simulator to practice breathing, tense muscles, and help maintain blood and oxygen flow." "Three, four!" "They also wear g-suits and special flight suits that compress their legs to squeeze the blood from the lower extremities towards their head to prevent blackout." "So..." "The real question is, who's gonna be the top gun for the g-forces?" "Well, these guys, the Red Bull pilots, rack up some insane numbers." "They regularly hit 10 Gs pulling off some incredible maneuvers." "And they're able to do this because they wear those special pressure suits to help maintain consciousness." "So, I'm going with these guys." "The Blue Angels." "These guys also pull up to 10 Gs and sometimes they maintain them for three seconds." "That is full G-LOC territory." "But unlike the Red Bull pilots, because of cockpit restrictions, they can't wear a G-suit." "Their bodies have to be trained to take 100% of the Gs." "And that makes them my choice for aerial g-force junkies." "Let's go over the criteria." "Number one, they pulled 10 Gs." "Number two, what's the duration?" "They hold those Gs for over three seconds." "Number three, the extreme factor?" "Did you see the video?" "In pursuit of the Holy Grail of medieval Gs..." "I've built a rig, simulated a joust... and I'm confident that my accelerometers will stand up to the heat of battle." "Time to give modern science a ride in the Middle Ages." "Try to look tough." " Hey, Charlie." " Hey, Grant." "I'm back and I'm armed with one of these." "This accelerometer is gonna tell us how many Gs your target knight experiences when you hit him." "All you have to do is hit him real hard." "I can hit him real hard." "Excellent." "His grandchildren will have headaches." "Ready to joust in the name of science?" "Absolutely." "We're gonna put physics to the test." "Mass plus acceleration equals ouch." "Ride fast and hit hard." "I'll meet you in the middle." " All right." " Let's go to war." "War." "Huh." "What is it good for?" "Medieval g-force data collection, actually." "But apart from that, absolutely nothing." "My knights, joust bravely... joust fiercely... but most importantly... joust consistently." "Ready?" "Ready?" "Go!" "Okay." "I'm probably gonna need some more data sets, so we're gonna have to keep jousting, okay?" "Charge!" "Yes!" "Give me more." "Are you not amused?" "We're gonna keep going until I'm satisfied we've reached peak Gs... or we break all the knights." "Oh!" "Can somebody check him?" "Yes!" "Just a splinter, right?" "God damn!" "That one hit hard." "Now, that's data." "Medieval style." "Charlie, that was fantastic." "That is the original drive-by." "I've always wondered..." "I mean, I've made 10,000s of these passes and had these hits and come off and I've always wondered, how violent is this?" "The highest run out of the whole day was the one where you didn't fall off the horse, and your target knight fell off." "That was 3.22 Gs." "He experienced over three times his body weight in acceleration as a result of being hit in the chest with your lance." "So, that's a massive hit." "That's a lot." "That is a head-on collision with two Volkswagens and no seatbelt." "It's brutal and we have the numbers now to back it up." "So, I set out to do something that had never been done before." "To find the number of Gs someone experiences while jousting." "What you experience is 3.22 Gs." "That's almost three-and-a-quarter times your body weight." "It's not insignificant." "The duration?" "Not that long." "But here is where I think jousting is gonna win." "Extreme factor." "Keep in mind that this is an activity that dates back to medieval times." "It has its roots in combat at a time when safety wasn't the highest concern." "It is scary as hell and that's why I think it's gonna win." "Charlie, thanks for your help." "Thank you." "It's been an honor." "And may g-force be with you." "Thank you, Father." "I am your father." "I know." "May the horse be with you?" "Oh!" "Nice one." "All right, Grant." "So, you maxed out at 3.22 Gs with the jousters?" "That's good, but it's nowhere close to the fliers." "Oh, come on." "Stapp kicks the living crap out of both your numbers." "Look, 3.22 Gs is nothing to laugh at." "Based on the size of the impact," "I thought it would have been higher." "So, what's next?" "Now, Grant and I are gonna go head-to-head in a competition between roller coaster versus Olympic bobsledder to see who has the most Gs." "Oh, it's on." "It's on like "Donkey Kong."" "You're going on a roller coaster." "I know." "It's awesome." "Ladies and gentlemen, please keep your hands and arms inside the ride at all times." "Do not stand up." "And enjoy your day..." "This is for science." "here on the Mindbender." "Okay." "Let's do this." "Okay, here we go." "We're going." "Okay, great." "Look at this thing." "Look how far up I'm going." "Dude, there's no way a bobsled is gonna beat this." "You kidding me?" "All right, here we go." "Okay, here we go." "Oh, sh" "Holy crap, holy crap." "Oh, my God." "Oh." "Oh!" "Oh, my God." "Here we go into the third loop." "Oh!" "Yeah." "That was a lot of Gs." "Aah." "Aah." "This is not fun!" "There's no way a bobsled's gonna beat this." "Oh, those are some Gs." "There goes some positive Gs right in the butt." "How do you guys do this?" "Oh..." "Oh, God, thank God, it's over." "No chance in hell his bobsled is gonna beat me." "That was insane." "Dude, that was nuts." "You didn't hear that screaming, did you?" "You're gonna edit that out, right?" "We're just like..." "I have to say, it wasn't enjoyable like a rollercoaster ride." "I'm pretty sure you're right." "That third loop is the one that had the most Gs." "Oh!" "Oh, my God." "Are you guys regretting letting me join your team?" "What's crazy is that this is so much more intense than I could have ever imagined." "You take a lot of abuse." "Yeah." "I felt like I was in a barrel that got rolled down a hill." "Thank you, guys." "I am honored." "Thank you so much." "I'm just glad..." "I didn't cause a crash." "Happy to have you." "Well, let's go look at the data." "All right." "A little help." "That was rad." " Do you have the data?" " Yes." "This is the data for the bobsled." "I'm hitting a peak speed of 82 miles an hour." "Now, it's really those tight corners that you hit going fast that build up those Gs." "So, what I'm really curious to see is turn 12 because that one, you really feel it in your body." "All right, so, that one..." "Wow, 5.6 Gs." "Let's see how the roller coaster stacks up." "Okay." "My turn." "The one I really want to show you is turn three." "At the bottom of this turn," "I get the benefit of having more or less my peak speed but also, like you, a decreasing radius." "Those two together give me my peak..." " which is 5.75 Gs." "Boom." " Wow." "That's interesting because you're going 55." "And I was going 85 getting less Gs." "When we take all the results from all the criteria, average them out, we get the final list and..." "We've gone from two guys on horseback to fighter jets that routinely break the sound barrier." "Let's see how our contenders rate using the three criteria." "Number of Gs." "Duration of Gs." "And extreme factor." "At number six, jousting." "With only two horsepower, it has the shortest duration of Gs." "But with all that carnage and chaos, it ranks at number two in extreme factor." "Coming it at number five, bobsled." "When Tory rattled into turn 12..." "Holy crap, holy crap." "he measured 5.6 Gs, which crushed him for a 1.5 second duration." "But his Olympic glory was short-lived... by losing to Grant's roller coaster at number four." "The carnival ride actually pinned him to his seat" "for a buttock-squashing 5.75 Gs." "Oh..." "And had him white-knuckling for a duration of 1.9 seconds." "In third position, race car." "Oh, my God." "The number of g-force experienced on turn one at Indianapolis was just below the bobsled, but is number one for duration, experiencing those Gs for a full five seconds." "Flying in at number two, The Blue Angels." "Pulling 10 Gs for up to three seconds, the extreme factor is so high, you can lose consciousness and your breakfast." "And at number one... the man who sacrificed his body to make life safer for every g-force junkie to come," "Colonel John Paul Stapp." "His 44-year-old body endured an eyeballs-out 25 Gs on the Sonic Wind." "And you can't get much more of an extreme factor than strapping yourself to a rocket sled." "Ah, those were the good old days." "He's the ultimate G-Force Jedi." "I mean, I could see that one coming." "Stapp." "I mean, it makes sense." "He's the godfather of Gs." "So, would you say he's the OG?"
