If you thought you'd heard enough from the 'euthanasia rollercoaster' guy, just know that his next theoretical invention is even more mind-boggling.
Lithuanian engineer Julijonas Urbonas is the man responsible for creating 'hypothetical death machines', as you've probably heard of his award-winning rollercoaster project in 2010.
His 1,600ft rollercoaster concept was designed to go up to 223mph, as each of the 24 passengers would experience a series of looping tracks, which get smaller and smaller as the rollercoaster progresses.
The 10Gs of force - which is essentially 10 times your body weight forcing down on you - would eventually kill you.
Now, during an exhibition in 2015, Urbonas spoke about another one of his theoretical inventions - the 'cumspin' - which was actually inspired from the euthanasia rollercoaster.

"I was collaborating with various physiologists, space medicine experts, and once I was dealing with physiology of a euthanasia coaster, new scientists would make jokes that you can make some adjustments in various nature coaster and make it into the most extreme sex machine," he told CCCB.
"So I took as a joke, and didn't spend much time on this joke, but all of a sudden, when I realised that what they meant was so called erotic as fixation, that it turns out it's very popular around the world.
"I thought, why not to make a safer means of doing that?"
He coined cumspin as an orgasm enhancing funfair machine, which causes a 'pleasurable death'.

"I use basically centrifugal force to produce a prolonged G force, so that people sitting, lying or being in these spherical capsules - this should be a three meter diameter capsules - they can do whatever they want inside," he added.
"And what we could do is basically control the distance between the centre of a cap of the amusement ride and the capsule, and the further from the centre you are, the more you are pinned to the walls of the capsule.
"And it is not just because you're attached to the wall. It is also because changing position in the capsule, you would control circulation of your blood."
Urbonas explains that passengers would die due to a lack of oxygen in the brain because there would be a lack of blood and your brain starts to suffocate.

"The suffocation of brain produces extreme euphoria," he said. "And when you combine this euphoria, produced by brain suffocation, with orgasm, these two ones produce the most extreme euphoria you might have in this world.
"So this, this machine is, is basically the most pleasant machine in the world I would say.
"Of course, it's a hypothetical, although scientific and technical background is real."
