Edit - Google says a small tent may be 2000 liters of air, so I guess it's best to get a couple more 4.5L nitrous oxide tanks to be sure


I'd made a thread earlier about stacking SN with N20 and was planning on using a bag

But if the tank is 4.5L of 99% food grade, would that not be sufficient to totally fill a small tent, meaning there's no need for an exit bag setup and the potential issues associated with those coming off.

I'd fill the tent, the the SN and then get into the tent with the tank still running and I hope that would knock me out and keep me unconscious for a long time


Google says

"A 4.5L (4500cc) professional nitrous oxide tank typically contains roughly 2000g to over 3000g of liquid
1773596837809

, which expands to approximately 1000–1500+ liters of gas at atmospheric pressure."


I can imagine that this would keep me unconscious during the SN and would also be lethal by itself

Looks like the commonly reccomended regatta Malawi 2 is about 3500 L inside, so I'm definitely going with a second and third tank if I do this to make sure its full

I'd put the tent in my garage and Crack the door a little to allow the excess to vent overnight, as I'd plan to CTB in the evening and not be found until the next morning or later, my concern is obviously gas build up hurting anyone else doing this

Are you still with us, friend? If so, are you still leaning toward this method?

To anyone wanting to try this, I have a lot of doubt that this is a viable method... The tent probably won't be airtight enough to not let oxygen/air replace the gas.

Agreed. You would need to at minimum put some sort of plastic sheeting around the tent to make it air tight and then put in some kind of vent to avoid pressure from building up.

yeah, like I get the intuition of why people would think this works, but the thing that kills you with inert gases isn't the gas itself, but the lack of oxygen

But I like the thought behind it. Placing a bag over my head or an uncomfortable mask doesn't sound good to me. Laying down, getting comfy and closing my eyes while the gas does its work sounds lovely.

Sadly there isn't a good method anymore that just allows you to lay down and peacefully go.
