Instead of an exit bag im going to go with a gas mask instead, I'm not quite sure how the mask I have works but if anything I'll try finding a different kind.

What i need help with is what kind of tubing should I use from the mask to the container of helium. I'm going to be using Balloon Time which I think with the helium shortage 80% mixed with a bit of oxygen but I don't think that should be a problem. The mask I have is a PMG2. I'm planning on doing it in my car in a garage or in bed. Is there anything else I should consider?

Thanks in advanced! I wouldn't want to fail and have to live with brain damage.

80% helium is not enough. Need 99%.
Why risk it? In that case,you're better off jumping....

Speaking from experience.
