Help with DIY exit bag

[briardweller]

I know this has probably already been discussed but I would genuinely appreciate help making a DIY exit bag.. I probably don't have access to the proper materials but without exposing myself, I've recently gained access to a huge tank of helium. I will figure out the exact model and specifications of it to figure out if I can get a more precise picture but right now I'm thinking duct tape and trash bags will do the trick so long as I have a few hours of unsupervised time with it. Please help me with acquiring a painless exit.

Hm.
I would advise you to get a large oven bag. Trashbags are usually pretty dark and that might cause you to panic.

Then you have to get yourself medical tape. Micropore is the name AFAIK.
And then you just need an elastic drawcord and a cordlock.

there is a video online called "Doing it with Chi" that shows the entire "assembly" process
