Inspired by a certain Pratchett book? That would certainly be a great way to go.
Maybe the very end is pleasant, but first there’s a few minutes of stark terror as you instinctively struggle to keep your head above water (or hold your breath as long as possible, if you’re far below the surface because of the cinder block you tied to your ankle).
There are far more pleasant ways to achieve the desired hypoxic state. a 10g roller coaster? Not so sure. I’ve experienced a couple of g’s before, and it was unpleasant; 10 g’s might be acutely painful (prior to cerebral hypoxia).
Hence the next line of my post: “Not that I think it would be pleasant, or that I think the people saying this know what they’re talking about, but that’s the theory.”
I once read a description (here, perhaps?) that involves a fairly elaborate setup and jumping off a bridge.
You put on a harness (on your torso) and attach it to bungees. You put a shorter cable - a really thin one, that can cut through meat when held taut, around your neck. It’s got to be 50ish feet long (or however long it would take for your body to build up a pretty good velocity by the time the cable is fully extended). Tie the bungees and the cable to the edge of the bridge.
Take a big-assed container of Krazy Glue or the like and coat both your hands, and then stick your hands to your head.
Then jump.
In a second or so, your body will extend that cable, which will very quickly decapitate you as you continue your descent. You reach the bottom of the bungees’ range, and bounce back up… where you bounce around, holding your own head in your hands.
Advantage: it’s quick, and the last thing you feel (aside from the “this is just a pinch” at the end) is WHEEEEEEEEEEE!!!
I once knew a cook in a candy factory who fell into a vat of peanut brittle and hardened to death.
It would be a lot cheaper if they just omitted the track after the top of the hill.
Same thing happened to a friend of mine at the Viagra factory.
A 10 gee rollercoaster isn’t going to kill anyone. 15 gees would be more like it, if it’s sustained long enough.
Indeed.
Pilots have passed out due to cerebral hypoxia at substantially less than 10 g’s after a period of just a few seconds. These are guys who are wearing G suits and are trained in the Anti-G Straining Maneuver.
For the untrained/unequipped, 10 g’s sustained for a minute will reliably induce fatal cerebral hypoxia.
