You may think you've heard of the most terrifying rollercoaster in the world - but unless it's Julijonas Urbonas's "Euthanasia Coaster," you'd be wrong. This is the rollercoaster designed to end the life of anyone who rides it - although it exists only in theory because, well, who'd want to build that thing?
But now there's another twist in the tale - Urbonas has revealed there may be a way to ride the rollercoaster and survive...
Now, the "Euthanasia Coaster" is an experience like no other.
Dreamt up in 2010 by designer and artist Julijonas Urbonas, it was designed to be a "hypothetic death machine in the form of a roller coaster, engineered to humanely - with elegance and euphoria - take the life of a human being."
Luckily, the idea currently exists only theoretically.
The design process uses scientific principles to ensure the rider will have the blood flow to their brain restricted.
If this happens for long enough, they suffer a painless death.
The coaster recently came to the internet's attention thanks to this TikToker.

"Julijonas Urbonas designed this roller coaster called the Euthanasia Coaster. It's capable of holding up to 24 passengers. Once they're all on board there's a slow ascent to the top, which is 510 [meters] in the air - that's just a little bit smaller than the tallest building in America, Luke Davidson explained.
"Once they're at the top it gives everyone the decision to stop and go back down safely. After that, everyone has to manually press a button to start the ride. Then it falls at a speed of 223 miles per hour, and goes through seven loops that keep getting smaller."
"Riding the coaster's track, the rider is subjected to a series of intensive motion elements that induce various unique experiences: from euphoria to thrill, and from tunnel vision to loss of consciousness, and, eventually, death," Urbanos explained on his website.
But now, he's revealed there may be a way to survive the (undoubtedly epic) experience.
"A possible usage is the 'hacked' thrill ride, which was suggested to me by an aeronautic engineer who happened to visit the coaster's scale model during an exhibition," he claimed.
So what's the hack? Antigravity suits, of course.
These are special suits designed for pilots to prevent them losing consciousness from lack of oxygen during acceleration. Thus, these suits could hypothetically prevent the effects of the death ride.
"Today, the roller coaster is at a stall of the innovation, as it has already reached the peak of bodily stimulation intensity. In the Euthanasia Coaster I wanted to overcome it, even dramatize, to celebrate this historical moment of the ride and the rider's body," the designer explained.
"It was a sort of a designed thought experiment of what the ultimate roller coaster would be like and what possible usages it would be open to."
Still, we aren't sure we'd take a ride - even in the proper safety gear...
