Ever sat on a lift hill, heart hammering against your ribs, and thought, "This thing is actually going to kill me"? For most of us, that's just a fleeting shot of adrenaline-fueled paranoia. We know the bolts are tight. We trust the sensors. But back in 2010, a PhD candidate named Julijonus Urbonas decided to take that intrusive thought and turn it into a high-concept engineering project. He designed the roller coaster to kill you, officially known as the Euthanasia Coaster. It wasn't built to be a fun day out at Six Flags. It was designed to be the last thing you ever did.
Honestly, the concept is pretty dark.
Urbonas, who had a background in amusement park development, wasn't just being edgy for the sake of it. He wanted to merge the "humane" nature of medical euthanasia with the "euphoric" thrill of a thrill ride. He called it "intellectual entertainment." Most people just call it terrifying. The design consists of a massive, 500-meter drop followed by seven increasingly smaller loops. It’s a mathematical certainty of death disguised as a world-record-breaking steel coaster.
How the Physics of the Euthanasia Coaster Actually Works
Gravity is a weird thing. When you go through a loop on a normal coaster, you feel "Gs"—the force of gravity pushing you into your seat. A standard ride might hit 4g or 5g for a split second. It’s enough to make your face feel heavy. The roller coaster to kill you takes that feeling and cranks it up to 10g for a full 60 seconds.
That is the "kill" mechanism.
It’s called G-LOC (G-force induced Loss Of Consciousness). When you hit 10g, the blood in your body literally can't reach your brain anymore. Gravity pulls it down toward your feet. Your vision starts to go first—peripheral vision vanishes, everything turns grey, and then it goes black. This is known as "greyout" and "blackout." If the force stays that high, your brain becomes oxygen-deprived. You pass out. Then, you die.
The loops get smaller as the train slows down. Why? To maintain that constant 10g pressure. As the train loses kinetic energy, the radius of the loop must tighten to keep the centrifugal force high enough to ensure the rider never wakes up. It’s a grisly bit of geometry. Urbonas designed it so the first loop does the heavy lifting, and the subsequent six are essentially "insurance" to make sure the process is completed.
The Controversy Surrounding Voluntary Death Machines
Not everyone in the scientific community was impressed by the "elegance" of the design. Dr. Desmond Tutu, the late Nobel Peace Prize winner, once expressed that the idea felt like a "grotesque" take on a sensitive issue. Critics argue that euthanasia should be a quiet, dignified medical process, not a spectacle.
But Urbonas had a counter-argument.
He felt that current euthanasia methods were "medicinal" and "cold." He imagined a scenario where a person could celebrate their life with a literal peak experience. You climb the hill—which takes several minutes—giving you time to reflect or even opt-out. There's a "stop" button on the way up. Once you drop, though, gravity takes over. It’s an irreversible mechanical process.
Is it "humane"? That depends on who you ask. From a physiological standpoint, some experts believe that high G-forces can be deeply uncomfortable before the loss of consciousness kicks in. You might feel a crushing sensation in your chest or limbs. Others point out that the "euphoria" promised by the designer might just be the disorientation of a brain starving for air.
Why This Ride Will Never Actually Be Built
Let’s be real: no insurance company on Earth is signing off on this.
The roller coaster to kill you exists as a 1:500 scale model and a series of complex blueprints. It has been exhibited in galleries like the Science Gallery in Dublin, but it will never move past the conceptual stage. Building a 500-meter tall coaster—that’s nearly 1,640 feet—is an engineering nightmare. For perspective, the world’s tallest current coaster, Kingda Ka, stands at "only" 456 feet.
The costs would be astronomical. The materials needed to support a structure that high, while maintaining the precision required for the loops, would run into the hundreds of millions of dollars. Plus, there's the legal side. Even in countries where assisted dying is legal, the regulations are incredibly strict. They require medical supervision and pharmaceutical protocols. A steel machine in a field doesn't exactly fit the legal definition of "medical care."

The Morbid Fascination with "Killer" Rides
We’ve always been obsessed with the idea of the "dangerous" coaster. Think back to the legendary Crystal Beach Cyclone or the original Coney Island Rough Riders. People want to feel like they’ve cheated death. The Euthanasia Coaster just takes that subtext and makes it the entire plot.
It’s a thought experiment about the intersection of technology and the end of life. It asks: if we have the technology to make death "fun," should we? Most people's gut reaction is a hard "no." There is something inherently "wrong" about mixing the joy of a theme park with the finality of the grave.
But the project continues to go viral every few years because it taps into a primal fear. We use machines every day that could kill us if they malfunctioned. This is the only machine that functions only when it kills you. It’s the ultimate subversion of what a roller coaster is supposed to be.
Practical Insights and the Reality of Coaster Safety
If reading about the roller coaster to kill you has made you a bit nervous about your next trip to Disney or Cedar Point, don't worry. Real-world roller coasters are some of the most over-engineered structures on the planet.
- Redundancy is King: Modern coasters have multiple braking systems. If one fails, the others are "fail-safe," meaning they default to the "closed" position to stop the train.
- G-Force Limits: Engineers follow strict ASTM (American Society for Testing and Materials) standards. They rarely let a ride sustain more than 4g or 5g, and even then, only for fractions of a second.
- Medical Screening: If you have a heart condition or high blood pressure, the signs at the front of the line aren't just legal fluff. They are there because even "safe" G-forces can trigger issues in vulnerable people.
While Julijonus Urbonas’s creation remains a dark piece of art, it serves as a reminder of how powerful physics can be. It’s a bridge between the world of entertainment and the philosophy of mortality. You probably won't be seeing a 500-meter drop on your local horizon anytime soon, and honestly, that’s probably for the best.
If you're genuinely interested in the intersection of engineering and ethics, looking into the history of "The Big Dipper" accidents or the engineering behind "Smiler" at Alton Towers provides a much more grounded look at what happens when coaster physics goes wrong in the real world. For now, the Euthanasia Coaster stays where it belongs: in a museum and in our nightmares.
Next Steps for the Curious:
- Research G-Force Tolerances: Look into how fighter pilots train for high-G environments. It’ll give you a better appreciation for why 10g is so lethal.
- Study Coaster Engineering: Check out "Ultimate Roller Coaster" or "RCDB" (Roller Coaster DataBase) to see the actual height and force limits of existing rides.
- Explore Bioethics: If the ethics of the Euthanasia Coaster intrigued you, read up on the current laws regarding assisted dying in countries like Switzerland or the Netherlands to see how the "real" process differs from Urbonas’s vision.
