Then he used inert gases such as nitrogen and argon.
Unlike carbon dioxide and the poison used in the gas chamber,
inert gasses have no detectable smell, taste or physical sensation.
So the body has no way of knowing that the oxygen in the air has been
entirely replaced by another gas.
The painless effect is confirmed by what the pig did next.
They woke up and just looked around
and went back to feed again on the apples, and that indicated to us
that it is a stress-free induction of unconsciousness.
And can I see this equipment? Of course you can.
So simple!
It is.
We have a source of nitrogen here.
Yeah. Taken through this tube,
and the gas is delivered using the face mask
to pigs restrained in this hammock.
And would you be able to change this mask
to a human mask and apply it to me?
Yes, you could, but I wouldn't recommend it.
Why? Because if you're inhaling pure nitrogen, you will be unconscious within 15 seconds.
15 seconds, really? That's right.
And how long to death? Within a minute.
Really? Yes. That's astonishing.
So this really is the perfect killing machine.
That appears to be the case, yes.
